Are there any risks or side effects associated with consuming horse milk, and how can they be prevented or managed?
Horse (mare's) milk is eaten in some regions, mostly as fermented kumis. The main risks are germs in raw milk, digestive upset, milk-protein allergy and the small amount of alcohol in fermented versions. Choose pasteurized or commercially made products, start with a small amount, and ask a doctor if you are pregnant, immunocompromised or allergic.

What are the risks of horse milk?
Horse milk is a niche food. It is drunk fresh or fermented as kumis (also called airag) in parts of Central Asia and is sold in a few places as a specialty product. The risks are mostly the ones that come with any milk, plus a few that are specific to fermented versions.
1. Germs in raw milk
The CDC warns that raw milk can carry germs such as Listeria, Salmonella, E. coli and Campylobacter. Its page does not name horse milk, but the same hygiene risk applies to raw milk in general. Children under 5, adults over 65, pregnant women and anyone with a weakened immune system are at higher risk of serious illness. Prevention: buy pasteurized milk or a commercially produced kumis that states how it was made.
2. Stomach upset and lactose
Sources I found disagree on how mare’s milk compares with cow’s milk for lactose, so do not assume it is lactose-free. Fermentation breaks down some lactose, but products differ. People who are not used to fermented drinks may get loose stools, gas or cramps. Prevention: start with a small glass and see how you feel.
3. Allergy
Horse milk is still milk. Someone with a cow’s milk protein allergy can react to it, and it should not be assumed safe. Prevention: do not try it without advice from an allergist.
4. Alcohol in kumis
Fermented mare’s milk contains a small amount of alcohol; sources give differing figures, roughly 1 to 3 percent. This matters for children, pregnant women, people avoiding alcohol, and drivers. Prevention: check the label and avoid it in these situations.
5. Unproven health claims
Claims that it cures illness or replaces medicine are not supported. The FDA found no scientific support for claims that raw milk cures lactose intolerance, treats allergies or builds immunity. Do not use horse milk as a substitute for medical care or infant formula.
When should you see a doctor?
Seek medical help if you get severe vomiting, bloody diarrhea, high fever, or any swelling, hives or breathing difficulty after drinking it.

Not without medical advice. Horse milk proteins can still cause allergic reactions.
