Myths and Facts about Raw Milk
By: Kara Lynch, Michigan State University Extension - 04/07/2021

Many people deny health dangers of drinking raw milk, and even promote it as a healthy practice. Exploring the facts is important to prevent foodborne illness.

Raw milk can harbor dangerous microorganisms that pose serious health risks. Pasteurization is a process that kills harmful bacteria by heating milk to a specific temperature for a set period of time. Some people continue to believe that pasteurization harms milk and that raw milk is a safe, healthier alternative. However, according to the United States Department of Agriculture (USDA), this belief could not be further from the truth.

Raw milk can harbor dangerous microorganisms, such as Salmonella, E.coli, and Listeria, all of which can pose serious health risks. In fact, the risk of an outbreak from drinking raw milk is 150 times higher than if you were to drink pasteurized milk. Older adults, young children, immune-compromised individuals and people who are pregnant are at the highest risk of contracting these illnesses. In fact, one study found young children have been involved with 59% of illness outbreaks due to raw milk consumption. The decision to drink raw milk is one that an adult can make for themselves, but serving it to children can have serious consequences that they may pay for the rest of their life.

Despite the many facts supporting the dangers of raw milk and the safety of pasteurized milk, some people still doubt and spread myths. Here are some common myths about milk and pasteurization, along with the facts from the Center for Disease Control and Prevention (CDC):

Myth: Pasteurization DOES NOT retain milk's nutritional value.

Fact: Pasteurized milk DOES retain most nutrients and is much safer than raw milk.

Myth: Milk from animals raised in sanitary conditions DOES NOT have pathogens.

Fact: Raising animals in sanitary conditions is important, but milk DOES still need pasteurization to be free of harmful germs, which can be introduced to the milk in a variety of ways even beyond the farm setting.

Myth: Organic milk DOES NOT carry pathogens.

Fact: Organic milk can still carry pathogens and DOES need to be pasteurized.

Myth: Pasteurized milk protects it from pathogen growth and DOES NOT need to be refrigerated.

Fact: Pasteurized milk DOES still have to be refrigerated, as pathogens can still grow if left in the temperature danger zone (40-140 degrees Fahrenheit)

Myth: Raw milk DOES NOT cause milk allergies and lactose intolerance.

Fact: Milk allergies are caused by a reaction to the milk protein and lactose intolerance is caused by a reaction to the sugar lactose -- neither of which are different in raw milk and DOES NOT protect you from these.

Do not sacrifice the safety of you or others you care for by drinking or serving raw milk. If you are working on eating healthier, follow USDA's evidence-based guidelines to get the most nutrients out of your diet.
