Annual Report for Raw Milk Institute

The Raw Milk Institute (RAWMI) is on a mission to improve the safety and quality of raw milk and raw milk products through farmer training, rigorous raw milk standards, raw milk research, and improving consumer education.

In 2020, RAWMI was awarded a 2nd grant from the Regenerative Agriculture Foundation (RAF) to further our work. RAWMI matches an economic benefit of stewardship of pastures and soils to high value raw dairy products for consumers. Safe raw milk from pastured cows can sustain the farm financially while the grazing improves the soils.

With the 2nd grant from RAF, RAWMI was able to accomplish much towards the overall goal of universal access to safe raw milk. With the unique challenges of 2020, RAWMI was able to adapt to the changing conditions and successfully develop new models for training and outreach.

Over the last year, RAWMI:

• Gave 14 raw milk training presentations (via Zoom)

• Trained over 500 farmers, legislators, university professors, and consumers on raw milk benefits and risk management (via Zoom)

• Prepared and presented an intensive 4.5 hour training course on Raw Milk Risk Management, for the Ohio Ecological Food and Farming Association (OEFFA)

• LISTED six new farms, who went through the process of developing an individualized Risk Assessment and Management Plan (RAMP) for managing the health and hygiene of their unique farms

• Provided one-on-one mentoring in the production of low-risk raw milk to over 25 additional farms in California, Michigan, Virginia, Michigan, Panama, Argentina, South Dakota, Hawaii, Montana, Washington, Tennessee, North Dakota, Oregon, Connecticut, and British Columbia

• Hosted quarterly meetings for LISTED farmers, which allow the farmers to stay up-to-date on the latest lessons learned for safe raw milk

• Amassed hundreds of raw milk test data from RAWMI LISTED farms 

• Attended and sponsored International Milk Genomics Consortium Conference (via Zoom)

• Collaborated with raw milk researchers in better understanding trends in raw milk-related outbreaks and illnesses

• Worked towards legalization of interstate raw butter and increased legal access to raw milk in Oregon and South Carolina

• Published 20 content pieces on the RAWMI website

• Provided on-farm lab grants to 4 farms

• Provided scholarships for OEFFA training to 10 farmers

Raw Milk Training

RAWMI taught about raw milk health benefits and safety throughout the United States. Whenever RAWMI teaches about raw milk risk management, soil and conditions management are emphasized as key elements in creating healthy, sustainable farms.

Dairy animals grazing on pastures provide a critical link to the soil biome and restorative farm practices. Pasture-based dairy farms produce healthy soils that are rehabilitated and renewed through the cycle of returning organic carbon to the soil in the form of plants biomass and manure. The resulting food that is harvested by either the animals or the farmer is rich in nutritional elements needed for human health.

Via Zoom, raw milk training was presented to over 500 farmers, legislators, university professors, and consumers in association with the following:

• Ohio Ecological Food and Farming Association

• Take Back Your Health Symposium

• Village Fitness and Physical Therapy

• Andrew Columbini (Los Angeles blogger)

• Pennsylvania Grazer’s Convention

• Mid-Atlantic Agriculture Convention

Attendees at RAWMI’s training classes provided feedback such as the following.

“I so enjoyed the RAWMI training yesterday. It was quite energizing to be surrounded virtually with like-minded individuals wanting to produce exceptionally high quality raw milk. For me, the combination of technical information and anecdotes is very effective for explaining why the RAWMI methods are important and how they solve a raw milk producer challenges. I came away with practical solutions to increase the quality/value of our milk and farm. Thank you."

“I left the Zoom meeting with a very clear understanding of what we are doing right and where we need to make changes. Beyond that, though, I left inspired to pursue excellence and cast a clear vision to everyone who is joining me in this endeavor.” 

 “The information was also rich and informative. I learned a ton and the systematic way you presented it was easy to follow and comprehensive.” 

“I cannot wait to move forward with you in becoming RAWMI Listed. We will be making some changes as we form our RAMP plan. We have already adjusted our milk chilling and have seen an improvement in flavor and longevity.” 

“Thank you for all you do. I have no doubt history will look back at the RAWMI as having played a crucial role in reforming raw milk production, health, and nutrition.”

“Excellent presentation that every single person who dairies for themselves and their family should take and learn from. Thank you very much.”

“This has been excellent!  ONLINE was so helpful as it’s hard to travel and be away.”

Farmer Mentoring  

RAWMI worked with individual farmers across the United States, Canada, and South America. RAWMI provided one-on-one mentoring and troubleshooting support for low-risk raw milk production, including helping farmers optimize their raw milk production, overcome problems in their milk systems and testing, and learn more about successful business practices.  This mentorship benefited farmers in:

• California

• Michigan

• Virginia

• Wyoming

• Panama

• Argentina

• South Dakota

• Hawaii

• Montana

• Washington

• Tennessee

• North Dakota

• Oregon

• Connecticut

• British Columbia

RAWMI LISTED Farms

RAWMI LISTED farmers are dedicated to producing clean, safe raw milk. The RAWMI listing process involves the development of individualized Risk Assessment and Management Plans (RAMPs) for managing the health and hygiene of each unique farm. RAWMI LISTED farms submit test data monthly to show that they are in compliance with RAWMI Common Standards, which target a rolling three-month average of <5,000 standard plate count (SPC) and <10 coliforms per ml of raw milk.

In the last year, RAWMI LISTED five more farms, in Virginia, Michigan, Kansas, and Wisconsin. To-date, RAWMI has LISTED 25 farms, and there are currently 20 active LISTED farms in the United States and Canada

RAWMI provided continuing support to all LISTED farmers to enable sustained excellence in low-risk raw milk. This included quarterly meetings for LISTED farmers, which allow the farmers to stay up-to-date on the latest lessons learned for safe raw milk, exchange ideas for improvements, and collaborate with the RAWMI Board of directors.  

RAWMI also sponsored general raw milk educational outreach and advertising through social media. This outreach specifically targeted regions across the United States where RAWMI LISTED dairies are located, to connect consumers to LISTED farmers. 

Raw Milk Research and Science

RAWMI’s mission includes supporting raw milk research and science. RAWMI LISTED farmers test their milk at least monthly for coliforms and Standard Plate Count (SPC). These tests provide a way to measure the amount of bacteria present in the milk, as well as providing a measure of the overall hygiene and cleanliness of the milk. Monthly testing serves as a useful confirmation step for ensuring that raw milk is being produced in a way that discourages pathogen growth and is therefore low-risk.

Test data from LISTED farms is submitted to RAWMI monthly. RAWMI amassed hundreds of test data from RAWMI LISTED farms over the last year.  This data can be used for raw milk research. 

RAWMI was a sponsor of the 17th International Milk Genomics Consortium (IMGC) and attended the virtual IMGC conference. As part of that conference, RAWMI is now engaged with international research and relationships with PhD researchers across the world. The IMGC provides access to the most leading-edge studies on milk genomics.

One of the studies presented at the conference this year was related to the loss of allergy-protective capacity of raw milk due to heating.  This study “tested the various heat-treated milk samples for their native protein profile and their allergy-protective capacity... the allergy-protective effect of raw cow's milk is lost after heating milk for 30 min at 65 °C [149 °F] or higher. This loss of protection coincided with a reduction in native immunologically active whey proteins.” The whey protein in raw milk provides protection from allergies, asthma, and inflammation.  When heated above 149 °F, these properties are dramatically reduced or eliminated. This finding is an important confirmation of the unique beneficial properties of whole, unprocessed raw milk. 

Raw Dairy Legalization and Support

RAWMI collaborated with the Farm-to-Consumer Legal Defense Fund (FTCLDF) towards the legalization of raw butter. Raw butter is an exceptionally nutritious food. For instance, the enzyme alkaline phosphatase (ALP) is found in the butter fat membrane that covers fat globules. ALP decreases inflammation in the body; it is associated with good health and less chronic illness, such as cardiovascular disease and Type-2 diabetes. Raw milk has 4% butter fat, but raw butter contains 86% fat and thus it is very high in alkaline phosphatase.  ALP enzyme is destroyed by pasteurization. The case for legalization of raw butter is currently going through the court system.  

RAWMI is also working towards legalization of raw milk in specific states.  RAWMI provided testimony to lawmakers in Oregon and South Carolina. Furthermore, RAWMI worked with the Organic Farmers Association and the National Farmers Union to create national policies for raw milk. 

Raw Dairy Educational Outreach

RAWMI created numerous educational materials and articles for raw milk consumers and the general public. 20 articles were published to the RAWMI website and social media, with a wide array of topics including:

• How to find a good raw milk farmer

• Immunity, the immune system, and raw milk

• Factory farms vs. sustainable local farms during COVID-19

• Raw milk, asthma, and lung health

• Advice for farmers considering the switch to raw milk

• Two types of raw milk

• Why humans drink raw milk

• Raw milk udder preparation

• Soil fertility and pastures for high-quality raw milk

• Why raw milk standards matter

• Raw milk and lactose intolerance

On-Farm Lab Sponsorships

RAWMI sponsored four farms in building on-farm labs for raw milk bacterial testing. On-farm lab testing is a powerful tool for raw milk farmers. It allows for frequent testing, so farmers can better identify issues before they turn into big problems, and it also helps immeasurably with troubleshooting when needed. On-farm labs require an initial investment of $800-$1,000, but once the lab is in-place the cost per test is only $1-$3. With RAWMI’s sponsorship, four farms were able to build their own on-farm labs for testing coliforms and Standard Plate Count.

Online Raw Milk Risk Management Training - February 10, 2021

On February 10th, the Raw Milk Institute (RAWMI) will be presenting a 4.5-hour Raw Milk Risk Management training workshop. This presentation will be livestreamed online, so that means you could attend from your own location. The presentation will be part of the 2021 Ohio Ecological Food and Farm Association Conference (OEFFA).

Kansas Raw Milk Micro-Dairy: Starting Small and Thinking Big

Starting a Farm as Grandparents

Like many other raw milk farmers, Shelley and Matt Harding didn’t start out intending to farm.  Shelley has worked as an electrician, cosmetologist, and more recently as an educator for medical coding.  Matt has a background in criminal justice and construction, and is currently a machinist for the railroad.

Their kids were grown, and Shelley and Matt were settling into their role as grandparents. Yet something was missing. Shelley and Matt found themselves re-connecting with old dreams of having a small farm. So, they purchased some farm land where they could expand their garden and raise more chickens.

But it wasn’t enough, especially for Matt.  He had fond memories of having a nurse cow and raising calves as a hobby during his teens and again in his twenties.  He recalled a certain peacefulness from spending time with his cattle. Now, decades later, Matt knew he wanted to have a cow again. But Shelley…

Shelley didn’t even *like* milk.  The taste and smell turned her off, and she’d had lactose intolerance symptoms for almost 20 years. Anytime she drank milk or milk products, she’d end up with abdominal cramping. Even still, Shelley knew how much it meant to Matt to have a cow again, so in the Spring of 2020 the Hardings brought home Miss Daisy, a pregnant Holstein heifer.

The Habit of Excellence

Shelley is a detail-oriented kinda person.  She naturally wants to do everything with excellence, and farming would be no different. If they were gonna have a cow and milk her, they were gonna do it right and do it well. Matt built a custom milking barn, and Shelley went to work on learning the ins-and-outs of safe raw milk.

With free mentoring from the Raw Milk Institute, the Hardings learned how to optimize their milking barn set-up, udder preparation, milking methods, bottling, and cleaning. They converted their basement into a milk bottling room, and worked hard to get the all of the details right.  

No More Lactose Intolerance or Allergies

But the milk… that was a big surprise for Shelley.  Miss Daisy’s raw milk didn’t smell or taste bad to Shelley like storebought milk had.  And Shelley didn’t have lactose intolerance symptoms with raw milk, either! 

Since she started drinking raw milk daily, Shelley no longer has gastrointestinal problems, and her seasonal allergies went away, too. No more allergy medications and no more sinus headaches. Raw milk helped their granddaughter overcome her allergies, too. The Harding’s experience aligns with scientific studies which have found that raw milk consumption is specifically associated with reduced rates of allergies.

Next Steps

Shelley and Matt’s S&M Farm is the newest dairy to be LISTED by the Raw Milk Institute.  They pride themselves on providing healthy, low-risk milk to a few families in Kansas.  Although Miss Daisy is their only cow for now, Shelley and Matt are already thinking about growing their dairy and building an on-farm lab for milk bacterial testing. The Raw Milk Institute welcomes S&M Farm to our community!

Why Raw Milk Standards Matter

Back in 2011 before the Raw Milk Institute (RAWMI) was formed, there were no universal standards for safe raw milk production. Consumer demand for raw milk was expanding, as people learned about the health benefits of raw milk as well as the negative effects of pasteurization. There was a growing body of evidence that children who drink raw milk have decreased rates of asthma, allergies, eczema, ear infections, fever, and respiratory infections. Whereas pasteurized milk is a top food allergen and difficult to digest, raw milk is actually a health-supporting food with rich therapeutic potential that is easily digested by most consumers. Yet, standards for raw milk varied widely from state to state and country to country. 

The occasional foodborne illness outbreaks that could be tied to raw milk continued to tarnish raw milk’s reputation.  And worse yet, some of these outbreaks actually led to life-threatening illnesses. As raw milk’s popularity grew, it was being consumed by a wider segment of the population including immune-compromised people. Whereas average healthy people are likely to have relatively mild symptoms from exposure to foodborne pathogens, immune-compromised people are more likely to have severe symptoms.

Perfectly Safe Food?

It is important to note that there is no such thing as a perfectly safe food. A CDC analysis of foodborne illnesses from 2009-2015 showed that the top food categories commonly linked to illnesses were chicken, pork, and seeded vegetables. Multi-state foodborne illness outbreaks have been linked to foods ranging from unpasteurized apple juice to ground beef to soy nut butter to lettuce.

Pasteurized milk is not perfectly safe, either, and is implicated in foodborne illnesses and outbreaks every year.  Although a wide range of foods including meats and vegetables are known to have the potential for causing foodborne illnesses, only raw milk is targeted by government regulators as a food to be completely avoided. Countries such as Canada and Australia currently have complete bans on raw milk.

Raw Milk Institute Method for Safe Raw Milk

The Raw Milk Institute was founded in 2011 to advance the cause of safe raw milk.  The numerous health benefits of raw milk make it an essential food, which is too important to be allowed to be systematically suppressed by regulators and government agencies. RAWMI sought to better understand the important factors in ensuring that raw milk was safe to consume.

In 2011-12, RAWMI brought together a diverse international group with the purpose of establishing standards for safe raw milk. This group included medical doctors and epidemiologists, nutritional consultants, veterinarians, food safety scientists, raw milk farmers, and raw milk consumers. This collaborative group developed the Raw Milk Institute Common Standards, which were initially released in 2012. 

The RAWMI Common Standards describe a three-pronged approach for the production of safe raw milk which consists of:

• Farmer training and mentoring

• Risk Analysis and Management Plan (RAMP) for the unique conditions on each individual farm

• Stringent yet achievable bacterial test standards for coliforms and Standard Plate Count (SPC)

The Common Standards Work!

Since their release in 2012, the RAWMI Common Standards have become a foundational part of low-risk raw milk production across North America. When farmers are well-trained, use careful production practices as laid out in their individual RAMP, and perform ongoing bacterial testing of their milk, they can produce raw milk that is ultra-low-risk.

Researchers from Canada and Europe have studied the safety of raw milk intended for direct human consumption, and have specifically considered milk from farms who implement the RAWMI Common Standards. They have found that carefully produced raw milk is a low-risk food which is fundamentally different from pre-pasteurized milk. The implementation of the RAWMI Common Standards has led to a significant reduction in raw milk-related illnesses and outbreaks.

The table below contrasts pathogen test data from pre-pasteurized milk vs. raw milk intended for direct human consumption.  As illustrated in the table, pathogen testing of pre-pasteurized milk samples has detected pathogens in up to 33% of samples.  In contrast, there were zero pathogens detected in thousands of milk samples from raw milk intended for direct human consumption. It is clear from this test data that pre-pasteurized milk is categorically different from raw milk intended for direct human consumption.

Common Standards and RAMP 2020 Update

Knowledge about safe raw milk is continually advancing. With the review of the RAWMI Advisory Board and LISTED farmers, the RAWMI Common Standards and RAMP have recently been updated to include the latest information about best practices in raw milk production. The updated Common Standards and RAMP are also now inclusive of other dairy animals such as goats and sheep. The 2020 Common Standards and RAMP are available here:

Soil Fertility and Pastures for High Quality Raw Milk

Feeding dairy animals on green sunny pastures is the preferred way to produce raw milk.  Paddock rotations that provide a daily cycle of movement to fresh, sunny, green pastures provides an ideal environment for keeping dairy animals healthy, clean, and producing high-quality raw milk.  In many cases when dairy farmers transition from an industrial confinement feeding model to a pasture-based feeding system, they are pleased to find that animal health often improves.  

Soil fertility and rotational grazing are of prime importance to pasture management.  Fertile soil is the main source for minerals taken up by the forage plants which dairy animals graze upon.  Soils supplied with calcium and phosphorus fortify milk with these minerals which are needed by people to build strong bones.     

Besides soil being a source for mineral enrichment of milk, a substantial body of scientific literature reports that milk produced by animals on pasture has enhanced nutritional properties compared to milk produced by confinement operations.  Milk produced during the grazing season has a more favorable ratio of omega-3 to omega-6 fatty acids.  Pasture raised milk also has higher levels of conjugated linoleic acid and fat-soluble vitamins that are beneficial to human nutrition.      

Whether soil fertility is managed or neglected can also influence the health of dairy animals.  Sometimes pasture lands are neglected and not managed to optimize soil fertility, forage quality, and health and productivity of grazing animals.  For example, an imbalance of the minerals calcium, magnesium, and potassium in soils can put animal health at risk.  When soil pH management and liming are neglected weedy plant species may be favored over the more nutritious leguminous forage species preferred by dairy cows.     

To produce raw milk of the highest quality, producers should make observations as they walk over the pastures grazed by dairy animals.  In weedy pastures where more desirable forage species are failing to thrive, it may be a sign of poor soil fertility or other mismanagement.  Soil sampling and testing for soil fertility status can be performed to help diagnose reasons for poor pasture performance.  Even on seemingly well performing pastures, regular soil fertility sampling and testing should be done about every three years to monitor soil pH and fertility status. 

A new publication Soil Fertility Recommendations for Pastures is now available online from Rutgers University, New Jersey Agriculture Research Station (E364 Soil Fertility Recommendations for Pastures. Heckman, J. https://njaes.rutgers.edu/e364 ).  Although this publication was specifically designed for New Jersey much of the information is universal.  The main soil fertility guidelines are most applicable to Eastern and Midwestern states. Higher levels of precipitation in the Eastern states cause nutrients to leach and acidify the soil.  This increases the need to apply limestone more frequently. 

In other regions, soil fertility needs, and testing procedures may be different and based on the local geological and climatic conditions.  For instance, soils in the arid Southwest tend to be alkaline and as such the pastures may benefit from acidifying soil amendments. Also, different climatic regions may grow different forage species.  To account for regional differences, farmers should consult with local expertise for soil fertility recommendations.

In summary, producers of fresh unprocessed milk are encouraged to make the best use of pastures as a major feed source during the grazing season.  When the soil fertility conditions are optimized for the health and productivity of dairy animals, farmers will be able to provide customers with nutritious dairy products of the highest quality.              

Udder Preparation for Raw Milk

Raw milk that is carefully and intentionally produced for direct human consumption is a low-risk food.  Udder preparation is one of the most important steps for producing clean, safe raw milk. If you don’t properly clean the udders and teats, dirt and manure contamination can contribute pathogenic bacteria into the milk. With proper cleaning and preparation of the udders and teats, the risk of pathogenic bacteria in the milk is dramatically reduced.

Manage the Environment

Got dirty, muddy udders? If so, that’s a sign that your farm conditions have some room for improvement. If you manage the farm environment properly, that will go a long way towards ensuring that your animals’ udders are fairly clean before even stepping into the milking parlor. The following are some important environmental factors to manage.

Clean and Dry Resting Places

If your animals are given a relatively clean and dry place to rest, they will be less likely to get filthy on a regular basis. Your individual farm will have its own unique challenges depending on the weather and landscape. Some examples of optimal resting areas are well-managed rotational pastures, compost bed packs in the barn, or other areas that are high, dry, and shaded.

Calves and Kids

Be aware that your animals’ offspring (calves, kids, etc.) can be a source of pathogens. Just like human babies, these animal babies explore the world with their mouths and can then directly transfer harmful bacteria to the udders. Animal babies have immature immune systems and are also more likely to harbor pathogens themselves. For low-risk raw milk production, ideally the calves/kids will be bottlefed and not allowed access to their mother’s udders. 

Chickens, Pigs, and Other Livestock

Poultry and livestock on the farm can be sources of pathogens as well.  For instance, if a cow lies down in a pasture with fresh chicken manure, her udders can become contaminated with salmonella or campylobacter pathogens. Ideally, the milk animals should be kept separately from other animals to reduce the pathogen risk.

Poultry should not be allowed into the milking parlor. Some raw milk farms choose to purposely rotate their chickens through the pastures after the cows/goats have moved through the pasture to ensure they are not sharing the space simultaneously.  If your chickens do share pastures with your milk animals, extra care will need to be taken to ensure the udders are properly cleaned before milking.    

Hair Management

Depending on the animal, there may be excess hair around the udders and teats. This hair can make it more difficult to properly clean the area before milking.  Regularly trimming the hair is one method for ensuring that proper cleaning can be achieved.

Additionally, the long tails on cows can become a source of contamination during milking when the cow switches her tail. Trimming the hair at the end of the tail is a good method for reducing this risk.  

Manure Management

Manure in the milking parlor can become a source of pathogen contamination, especially for cows which have much messier manure than goats and sheep. The milking parlor should be cleaned of manure on a daily basis before, during, and after milking. Giving cows a brief standing period or walk before leading them into the milking parlor is another method for reducing the amount of manure in the milking parlor.

Pre-Milking Udder Preparation

The end goal of udder preparation is for the udder to be clean and dry at the time of milking. A basic procedure to achieve this is as follows.

1.       Clean the udder and teats

2.       Pre-dip each teat in an iodine- or hydrogen peroxide-based teat dip

3.       Wipe off the teat dip

4.       Strip each teat and inspect the milk

5.       Apply the milking machine

6.       After milking, apply iodine-based post-dip to each teat

Each farm has its own unique challenges. There is no one procedure that will work perfectly for all farmers at all times. Here are some specific pointers that may help you in developing your own best udder preparation procedures.

Clean the Udder and Teats

If the udder and teats are very dirty, such as caked with mud or manure, you may need to do a wet soapy wash of the area first. There is no need to wet down the whole animal, as that will make it more likely for contamination to drip down onto the udders. Remember that wetness will allow bacteria to migrate from one area to another, and any bacteria is likely to end up at the low point which is the teats. If you must wash the udder and teats, make sure to dry them well before proceeding with the damp cloth wiping steps below. 

If the environment has been managed well, the udder and teats will probably be relatively clean when the animal enters the milking parlor. Use a clean, damp cloth to wipe off the teats and udder. Make sure to wipe from the teats outward, so that the teats are the cleanest parts. Using white cloths will allow you to easily see whether there is still any dirt or filth coming off the teats/udder.

Make sure to use a new cloth for each animal, and you may even need to use multiple cloths per animal to make sure the teats are well-cleaned. Have a separate bucket to place the soiled cloths into, so they don’t contaminate the clean cloths.

Pre-dip Teats in Iodine- or Hydrogen Peroxide-Based Teat Dip

After cleaning the udder and teats, pre-dip the teats. Both iodine and hydrogen peroxide-based teat dips are approved for organic milk production.

Iodine-based teat dips have been used successfully since the 1960’s and have a longer shelf life than hydrogen peroxide-based dips. Because iodine-based teat dips have a thicker consistency, care needs to be taken to ensure that the pre-dip is properly wiped off before milking. Iodine-based teat dips are currently quite expensive.

Hydrogen peroxide-based teat dips are much less expensive than iodine-based dips, but they also have somewhat less effectiveness in preventing mastitis. Hydrogen peroxide-based teat dips have a thinner consistency and thus can work well in spray applications. Care needs to be taken to ensure that the spray is applied to all sides of the teats.

Make sure to leave the pre-dip on for at least 30 seconds so that it has appropriate time to sanitize the teats. Beware not to dip dirty udders into your teat dip, else you may end up contaminating the whole cup! 

Once the teat dip has been on for at least 30 seconds, wipe off the teat dip with a clean, dry cloth.

Dip Then Strip, or Strip Then Dip?

It does not appear to matter whether you strip the teats and then pre-dip, or dip first and then strip the teats. Data from the National Mastitis Council has shown that there is “no significant difference in the monthly rate of clinical mastitis, new subclinical cases or milk per cow per day" whether the teats are stripped-then-dipped or dipped-then-stripped. Either way, the important thing is to build consistency and stick with your procedures. 

Strip Each Teat and Inspect the Milk

Using clean or gloved hands, manually strip a few squirts of milk out of each teat. Inspect the milk for any signs of coagulation, stringiness, blood, etc. If there is anything abnormal, the milk is best discarded or used for some other purpose rather than direct human consumption.

Apply the Milking Machine

Once the teats have been cleaned, dipped, stripped, and dried, you are ready to apply the milking machine. Manage the milk claws such that they never touch the ground, and are quickly applied to the teats once the vacuum is turned on.

After Milking, Apply Iodine-Based Post-Dip

Once the milking is done, apply an iodine-based post-dip to the teats. This will help to seal the teat orifice against bacteria. Try to ensure that the animals remain standing for at least 30 minutes after applying the post-dip; this will allow the dip to fully dry before there is any potential contamination from lying down.

Example Udder Prep Video

Here is a video example of udder preparation, so you can see some of the principles of proper udder preparation in action. Remember that each farm is unique, and there is no solitary procedure that will work perfectly for all farmers at all times.

Advice for Farmers Considering the Switch to Raw Milk

In today’s unpredictable world, many dairy farmers are interested in selling raw milk. Due to the domino-effect of changes in the supply chain due to COVID19, many dairy farms are having to dump their milk. The dairy processing industry which was previously supplying milk to schools and restaurants cannot rapidly adapt to bottling and delivering milk for retail sales. Selling raw milk may seem like a good alternative to many of these dairy farms, but in actuality this would be a complex change requiring a large amount of forethought and precaution.

Demand for raw milk is increasing in recent years as consumers learn about raw milk’s significant health benefits. Raw milk consumption has been correlated to decreased rates of asthma, allergies, eczema, ear infections, fever, and respiratory infections. Raw milk consumption has also been correlated with improved lung health, and many consumers who are lactose intolerant can actually consume raw milk with no problems.  Plus, raw milk tastes great! Raw milk’s deliciousness is one of the main drivers for why consumers choose raw milk over pasteurized milk. 

It’s Not a Trivial Change

Switching from producing milk intended for pasteurization to raw milk intended for direct human consumption requires a huge shift in mindset and practices. Studies have shown that up to 24% of pre-pasteurized milk contains pathogens, whereas raw milk from well-trained farmers is very unlikely to contain pathogens.

Farmers who produce low-risk raw milk carefully manage the cleanliness and hygiene of the farm as a whole from grass-to-glass. From the health of the herd, to cleanliness of the milking parlor, to the specific cleaning processes for the milk line, to ensuring rapid milk chilling, to regularly testing their milk, and everything in between, raw milk farmers have to be dedicated to taking their farm management to the next level in order to ensure that their raw milk is safe to consume.

For dairy farmers who are considering the switch to raw milk production, here are some specific guidelines for producing safe raw milk.

Cleanliness

Cleanliness is of paramount importance in producing raw milk. Your whole milking system, from udders to bottling, must be cleaned exceptionally well, or else there is a much higher likelihood that the milk will end up tainted with pathogens.

Udder preparation and cleaning is of particular importance, since dirty udders are the most probable source for pathogens in milk. Udders need to be clean and dry at milking.  For raw milk production, udder prep typically includes:

• brushing and/or cleaning the udders to make sure they are hygienic

• using a clean rag and towel for each cow/doe

• applying iodine-based teat dip, which is left on for at least 30 seconds

• wiping off the teat dip with a clean, dry towel

• stripping each teat with clean hands or gloves, and inspecting the milk to look for any signs of clotting, blood, etc.

(More details on udder prep are given here.)

Special care needs to be taken to ensure that the milking system, chiller, and tank are cleaned frequently and thoroughly.  Typically, the milking system needs to be cleaned after each milking with cool/tepid water first, followed by very hot alkaline cleaner, and then finished with hot acidic cleaner. Milk tanks need to be cleaned frequently, including complete disassembly and cleaning of the tank valve.

Milk bottling should ideally occur in a clean, uncluttered room with smooth washable walls and floor. Care should be taken to ensure that the milk bottling room is kept clean and is not contaminated with manure or other filth.

Herd Health

Herd health is very important in raw milk production, as unhealthy animals are more likely to develop infection and mastitis which increases the likelihood of having pathogens in the milk. Your raw milk herd must be verified to be free of tuberculosis, brucellosis, and Johne’s disease. Biosecurity must be carefully managed to ensure that the herd does not come into contact with other animals (wild or domesticated) that may be carrying disease.

Rapid Chilling and Maintaining the Cold Chain

Under ideal growth conditions, bacteria counts double every 20 minutes.  Increased bacterial counts are associated with faster milk souring as well as greater presence of pathogens.  Decreased temperatures slow bacterial growth dramatically, and thus it is quite important to make sure that raw milk is rapidly chilled to slow bacterial growth. Ideally, raw milk should be chilled to 38F within an hour of milking. Keep raw milk cold throughout the bottling process and all the way through customer receipt of the milk.

Preventing Cross Contamination

Be aware that other farm animals such as chickens, rodents, birds, and pigs can pose a pathogen threat. For instance, chickens may carry salmonella and campylobacter, and cows/does that lie down in chicken manure may end up with pathogen contamination on their udders. Your milking herd should be kept separate from pigs and chickens. Chickens and birds should be kept out of the milking barn.

Milk stacking occurs when milk from subsequent milkings is placed in the same tank. Milk stacking is to be avoided as much as possible because it increases the likelihood of having bacterial problems. One bad batch can contaminate the rest. Additionally, milk stacking raises the temperature of the previously-cooled milk, making it more likely to support bacterial growth.

If your farm will produce both pasteurized and raw milk, you’ll need to take special care to ensure that the pasteurized milk is kept completely separated from raw milk. Pasteurized milk provides an ideal growth environment for pathogenic Listeria mono be can because there is no beneficial bacteria present to outcompete the Listeria.

Regular Testing

Don’t make the mistake of assuming that, just because your family can drink your raw milk with no problems, there are no pathogens present. Farm families have robust immune systems due to repeated exposure to the farm environment, so they are less likely to become ill from raw milk.  However, if you are selling raw milk to the public, you may end up with customers who have weak or impaired immune systems.  These customers will have a much lower threshold for illness from pathogens than farm families.

Testing is an important part of safe raw milk production. Testing provides a verification step that the practices and procedures are working well to produce low-risk raw milk. According to the Raw Milk Institute (RAWMI) Common Standards, raw milk should be tested regularly for coliforms and standard plate count. These tests provide a good indication of the hygiene, cleanliness, and handling of the milk. The Common Standards call for <10 coliforms/mL and <5,000 for SPC.

Take Care of Your Market

Selling to people versus selling to a processor: It’s an entirely different and very rewarding world. If you get it right, you’ll become a trusted brand and be beloved. 

As farmers who want to switch into the raw dairy market, besides following high standards for cleanliness and farm management, one of the biggest changes for you will be selling directly to people, kids, and families. You will no longer sell to a processor. The families you provide raw milk to trust you, and you’d better do an outstanding job! 

Building a market for raw milk does not just happen. Selling to a processor doesn’t require answering questions from end consumers or developing close consumer relationships. You’ll have to work hard to develop each relationship with your consumers, and be prepared to answer lots of questions. You must be interested in answering these questions and carefully researching to assure that the most current and accurate information is provided. All of this needs to be done with a warm smile :) and some compassion. 

As we say at RAWMI, “You don’t sell raw milk. You teach it”. If you teach enough, you can sell enough. It’s all about making that consumer connection with very high quality and safety. 

That means you become both a teacher and a producer.  If consumers don’t know what is so great about raw milk... they won’t buy it.  Why would they? They must learn first, then the sale is a done deal. Knowledge is gained and trust is earned before a sale is completed.

RAWMI Ripple - January 2020

January 2020 Edition

Dear Friend,

Welcome to the January 2020 edition of the Raw Milk Institute (RAWMI) Ripple. Herein you'll find information about the latest in the world of raw milk, including a new meta-analysis on the protective health effects of raw milk, the Interstate Milk Freedom Act, RAWMI training, and additional resources for raw milk education.

Meta-Analysis of Raw Milk Effects on Asthma, Allergies, and Infections

A recent issue of the Journal of Allergy and Clinical Immunology: In Practice published a peer-reviewed meta-analysis of eight health studies related to raw milk. A meta-analysis is a quantitative statistical analysis which combines the results of multiple scientific studies, thereby allowing the researchers to derive overall conclusions about that body of research.

The November 2019 paper, titled “The Beneficial Effect of Farm Milk Consumption on Asthma, Allergies, and Infections: From Meta-Analysis of Evidence to Clinical Trial” was written by a team of researchers from the Netherlands and Germany. The meta-analysis concluded that, when taken as a whole, the body of data from the previous studies shows that raw milk consumption in childhood has a protective effect on asthma, current wheeze, allergic rhinitis (hay fever), and atopic sensitization (allergies to environmental triggers).

When the previous raw milk studies were criticized, the detractors instead attributed the protective health effects to the farm environment rather than raw milk. However, the 2019 meta-analysis shows differently: “The effect particularly on asthma was observed not only in children raised on farms (OR, 0.62; 95% CI, 0.58-0.82) but also in children living in rural areas but not on a farm (OR, 0.60; 95% CI, 0.48-0.74). This demonstrates that the effect of farm milk consumption is independent of other farm exposures and that children not living on a farm can theoretically profit from this effect.” 

Interstate Milk Freedom Act HR 5410

It is currently illegal to sell raw milk across state lines in the United States. The FDA’s ban on interstate raw milk harms small farms as well as informed consumers, who purposely seek out raw milk for its health benefits and superb taste. The Interstate Milk Freedom Act HR 5410 seeks to prohibit federal interference with the interstate sale of raw milk. This bipartisan bill was sponsored by Representatives Thomas Massie (Republican from Kentucky) and Chellie Pingree (Democrat from Maine).

“Federal agencies, such as the FDA, that are part of the executive branch do not and should not have the power to shut down trade between peaceful farmers and willing consumers. It is Congress’s job to legislate,” said Rep. Massie. “Our Interstate Milk Freedom Act would make it easier for families to buy milk of their choice by reversing the criminalization of specific dairy farmers.”

“So many people across the country want to make sure their food is fresh and local—including fruits, vegetables, and even their milk,” said Rep. Pingree. “Raw milk is currently the only food banned for interstate commerce—an onerous regulation that hurts small farmers for selling milk straight from their cows to the consumer.”

It is time for the ban on interstate raw milk to be overturned. Ask your representatives to support HR 5410.

Northeast USA RAWMI Training

Studies have shown that raw milk has superb nutrition and protective health effects, but raw milk needs to be carefully and intentionally produced in order to ensure that it is a low-risk food. Through education, outreach, and research, RAWMI is working towards universal access to safe raw milk for everyone.

Earlier this month, RAWMI held raw milk training sessions at Rutgers University, the Northeast Organic Farming Association (NOFA) Massachusetts, and NOFA New York. These presentations focused on raw milk benefits as well as risk management for the production of safe, low-risk raw milk. 50 dairy farmers attended these three training sessions.

On February 6, 2020, RAWMI will be providing a 3&1/2 hour presentation on raw milk risk management at the Pennsylvania Association for Sustainable Agriculture (PASA) conference in Lancaster Pennsylvania. Mark McAfee, Sarah Smith, Dr. Joseph Heckman, and Edwin Shank will be presenting at this event.

International Milk Genomics Consortium Conference

The 16th International Milk Genomics Consortium (IMGC) Symposium was held on November 12-14, 2019 in Aarhus Denmark. This conference focused on milk and health from a sustainability perspective, with a wide variety of presentation topics including environmental challenges in milk production, effects of breastmilk and ruminant milk on the gut microbiome, structure and function of milk, and the superb nutrition of whole foods versus supplements.

The Raw Milk Institute was an official sponsor of this IMGC Symposium and provided sponsorship to Dr. Joanne Whitehead in attending to present her peer-reviewed, published raw milk risk analysis poster depicting the positive impact of “high standards, farmer training and frequent testing” on raw milk risk reduction.

New Resources for Raw Milk Education

The Raw Milk Institute has developed several new resources for educating people about raw milk.

RAWMI’s letter to medical professionals about the benefits and safety of raw milk provides a comprehensive summary of the latest science on the nutritional and health benefits of raw milk, therapeutic use of raw milk, the negative impacts of pasteurization, and the safety of raw milk.

In response to a request from RAWMI LISTED farmers, RAWMI has also developed a new trifold brochure about the benefits of raw milk. This brochure can be used at the point-of-sale or online to increase awareness of the benefits of raw milk. Email sarah@rawmilkinstitute.org if you want to make use of this brochure.

LISTED Farmers Quarterly Meeting

RAWMI LISTED farmers are able to connect and share with other raw milk farmers during quarterly video conferences. At the most recent video conference, farmers from 11 RAWMI LISTED dairies discussed issues including challenges to exclusive grass-feeding, recent problems and lessons learned, marketing, and the erosion of the “organic” label.

Ancient Baby Bottles Reveal Ruminant Milk Being Fed to Children

Raw milk has been nourishing children for millennia! The oldest baby bottle-like vessel found thus far is nearly 8,000 years old. Recently, three independent lipid analyses of residue from ancient baby bottles has been performed. These analyses have provided evidence that ruminant milk (such as cow, sheep, or goat milk) was being fed to children thousands of years ago.

Take care all of you RAWMI producers, consumers and all of you interested in raw milk!
