Raw, unpasteurized milk has surged in popularity, with advocates claiming it offers superior nutrition, boosts immunity, and cures ailments from allergies to lactose intolerance ^³. The scientific evidence points strongly the other way: there is little proof that raw milk is nutritionally superior, and it carries real, serious risks of foodborne illness ^³. Between 1998 and 2018, the CDC linked raw milk to 202 outbreaks causing 2,645 illnesses and 228 hospitalizations, and the FDA, CDC, and food scientists all recommend choosing pasteurized milk instead ^¹. Here is a fair look at the science.

What Is Raw Milk?

Unpasteurized milk is milk from cows, goats, sheep, or other animals that has not been pasteurized ^¹. Pasteurization is the process of heating milk to a specific temperature for a set time to kill disease-causing germs, first developed by Louis Pasteur in 1864 and widely adopted in the early 1900s ^¹. That single innovation dramatically reduced milk-borne diseases like tuberculosis, typhoid fever, listeriosis, and brucellosis ^¹. Raw milk advocates argue that this heating destroys valuable nutrients and beneficial compounds, which is the central claim behind the raw-milk trend ^³.

The Nutrition Claim

The idea that pasteurization strips milk of its nutritional value does not hold up ^². According to public health agencies and food scientists, pasteurized milk offers the same nutritional benefits as raw milk without the risks ^². Decades of research have failed to identify meaningful differences in the nutritional value of raw versus pasteurized milk ^⁵. Popular claims that raw milk cures lactose intolerance, asthma, or allergies, prevents osteoporosis, or improves gut health are unfounded, and the FDA has published a fact sheet specifically debunking each of these misconceptions ^⁴. In short, you are not gaining nutrition by choosing it ^².

The Real Risks

Where raw milk clearly differs is in safety ^¹. It can carry dangerous germs, including Salmonella, E. coli, Listeria, Campylobacter, and Cryptosporidium, all of which cause foodborne illness ^¹. Crucially, anyone can get sick from it, even healthy adults, and the consequences can be severe ^². These germs are especially dangerous for children and teenagers, who are most affected, as well as older adults, pregnant women, and people with weakened immune systems ^¹. For pregnant women in particular, Listeria found in it can cause miscarriage or stillbirth ^¹. Good hygiene practices on farms can reduce contamination but cannot guarantee that it is safe ^².

The Bird Flu Dimension

The ongoing bird flu outbreak in dairy cattle has added a new concern ^³. Cows infected with H5N1 avian influenza can shed viral material into their milk, and farmworkers have contracted the virus from handling infected animals and their byproducts ^³. Reassuringly, pasteurization inactivates the H5N1 virus, and FDA testing found that while some retail milk samples contained viral traces, none contained live virus — evidence that pasteurization works ^³. Milk from infected herds is also diverted or destroyed ^³. The CDC explicitly warns against drinking it in an attempt to build immunity to bird flu, since it could instead expose you to the live virus ^².

The Awareness Gap

Part of what makes this trend concerning is how many people misjudge the risk ^⁵. Surveys have found that only about 56 percent of Americans understand that drinking raw milk is risky, and even fewer know that bird flu has been detected in unpasteurized milk but not in pasteurized milk ^⁵. This gap between public perception and scientific consensus is exactly the environment in which a risky trend can spread ^⁴. Choosing pasteurized products remains the clear, evidence-based way to enjoy milk's nutrition safely ^².

The Fair Bottom Line

Unpasteurized milk is a case where the science is unusually one-sided: it offers no proven nutritional or health advantage over the pasteurized version, while carrying genuine risks of serious foodborne illness that pasteurization is specifically designed to prevent ^³. Public health authorities including the FDA and CDC uniformly recommend choosing only pasteurized milk and dairy products ^¹. If you or a family member consume unpasteurized milk and become ill, seek medical attention promptly — and this is general information, not medical advice ^¹.

Frequently Asked Questions

Is unpasteurized milk more nutritious than pasteurized milk? No. Research finds no meaningful nutritional difference, and pasteurized milk provides the same benefits safely ^².

Is unpasteurized milk dangerous? Yes. Unpasteurized milk can carry germs like Salmonella, E. coli, and Listeria, and anyone, even healthy adults, can get sick ^¹.

Does it cure lactose intolerance or allergies? No. These claims are unfounded, and the FDA has specifically debunked them ^⁴.

Can you get bird flu from unpasteurized milk? The virus can appear in raw milk; pasteurization inactivates it, so pasteurized milk is safe while raw milk is not ^³.

Who is most at risk? Children, pregnant women, older adults, and people with weakened immune systems face the greatest danger ^¹.
