In the growing movement toward natural and minimally processed foods, raw milk has reemerged as a popular but controversial choice. Advocates praise its taste and purported health benefits, while health authorities like the FDA and Harvard Health warn of serious safety risks. So, what’s the truth behind raw milk—and is it really better than pasteurized milk?
What Is Raw Milk?
Raw milk is milk that has not undergone pasteurization, the heat treatment process designed to kill harmful bacteria. Supporters of raw milk often argue that it retains more nutrients, enzymes, and probiotics than pasteurized milk. They believe it can aid in digestion, strengthen the immune system, and even help with lactose intolerance.
However, these claims are largely anecdotal. According to Healthline, while raw milk contains essential nutrients like protein, calcium, and fatty acids, pasteurization does not significantly diminish these nutrients. Scientific reviews have found no substantial evidence that raw milk provides health advantages over pasteurized milk.
The Proven Dangers of Raw Milk
Despite its “natural” appeal, raw milk is associated with very real health risks. The FDA, Harvard Health, and WebMD all point out that raw milk can be contaminated with dangerous pathogens, including:
-Salmonella
-Escherichia coli (E. coli)
-Listeria monocytogenes
-Campylobacter
According to the FDA, from 1998 to 2018, there were 202 reported outbreaks linked to raw milk in the U.S., leading to over 2,600 illnesses and more than 200 hospitalizations. These illnesses can range from mild gastrointestinal symptoms to severe, life-threatening conditions, especially for pregnant women, young children, older adults, and those with weakened immune systems.
More recently, raw milk has come under scrutiny for possibly carrying the avian influenza (bird flu) virus. The FDA has reported bird flu outbreaks in dairy cattle, and some clinical samples of raw milk have tested positive. Domestic cats have even died after consuming contaminated raw milk. This has led to renewed warnings about the unpredictability and dangers of unpasteurized dairy.
Pasteurization: A Safe and Effective Public Health Tool
Pasteurization was developed over a century ago and is now a cornerstone of food safety. It involves heating milk to a specific temperature for a set time to kill bacteria without compromising its nutritional value.
As Harvard Health emphasizes, pasteurization dramatically reduces the risk of foodborne illness while retaining the core benefits of milk: high-quality protein, calcium, vitamin D, and essential fatty acids. The idea that pasteurization “kills” milk is a myth; in reality, it makes milk safer to consume without significant nutrient loss.
The Bottom Line
While raw milk continues to attract interest from those seeking natural alternatives, the science is clear: the risks far outweigh the benefits. There is no compelling evidence that raw milk is nutritionally superior to pasteurized milk, and the dangers—ranging from bacterial infection to viral exposure—are well-documented.
For consumers who value both health and safety, pasteurized milk remains the smart choice. It delivers all the essential nutrients of dairy without the health hazards that raw milk can pose.
