Raw Milk Handling Risks

What does raw milk mean?

Raw milk is milk that has not been pasteurized, which is the heat treatment used to destroy harmful bacteria. It comes straight from the animal, and it can be handled with great care or very poorly, which is why outcomes vary.

Public health agencies, including the CDC and USDA, consistently warn that raw milk can carry harmful bacteria. Careful handling can lower the risk, but cannot remove it entirely.

Terms on labels can be confusing. Ask any seller what the milk is, how it was handled and whether it was tested, and remember that testing is not a guarantee.

What risks are linked to raw milk?

Organisms that cause serious illness can be present in raw milk even when the animal looks healthy and the dairy looks clean. Illness can range from a stomach upset to severe and lasting harm.

Because these risks cannot be seen, smelled or tasted, a clean-looking milk is not a guarantee of safety. Public health sources describe raw milk illness outbreaks and urge caution.

• Harmful bacteria can be present in healthy animals
• Milk can look and smell normal while unsafe
• Careful handling reduces but does not erase risk
• Illness can be serious

Who is at greatest risk?

Young children, older adults, pregnant people and anyone with a weakened immune system face the greatest danger from raw milk. For these groups, health agencies advise against drinking it.

If you serve milk to guests or share it with neighbors, remember that you may not know their health history. Ask your doctor or your local public health office about risks for your household.

Children often like milk and may not understand the risk, so adults need to make the choice. Talk to your pediatrician before serving raw milk to a child.

How does handling change the risk?

Good handling matters a great deal. A healthy, well-cared-for animal, clean milking, sanitized equipment, rapid cooling and cold storage all reduce the chance of contamination. A lapse in any one step can raise the risk.

Do not assume a long family history of drinking raw milk without trouble means it is safe. Bacteria can enter at any time, and the one batch that goes wrong is the one that matters.

Keep raw milk cold, covered and separate from ready-to-eat foods, and use clean containers. Wash anything that touches it, including your hands and counters.

What are the alternatives?

Many households pasteurize milk at home using a current tested method and use it for drinking and cooking. Pasteurization changes some qualities but removes most of the risk of illness. Tested sources and your extension office can describe suitable methods.

Cooking with milk, such as in custards, puddings and sauces, also heats it. That is not a substitute for a safe supply, but it is one more reason to ask about the way you use milk.

Cultured foods such as yogurt and cheese made from raw milk still carry risks. Heating, culturing and aging do not guarantee safety, so ask your extension office.

What are the rules about raw milk?

Laws about raw milk differ widely. In some places sale is allowed, in others only herd shares or on-farm sales, and in others it is banned. These rules can change, and they vary by state, county and town. Do not rely on what a neighbor says or on a rule remembered from elsewhere.

Ask your state department of agriculture, your state veterinarian and your local health office what applies to you, including rules on sharing, selling, labeling and testing. Do not assume that a rule allowing one activity allows another.

What should I tell guests and buyers?

Be honest. If you serve or share raw milk, say plainly that it is raw and that it carries risks. Let people decide for themselves and never push it on children or on anyone who may be vulnerable.

If you sell milk, rules on labeling and warnings are set locally, so ask your state agriculture department before you start. Do not assume a handshake arrangement avoids the rules.
