Raw Milk Dangers and Risks



Unpasteurized Milk Can Pose a Serious Health Risk

Milk and milk products provide a wealth of nutrition . But can harbor dangerous microorganisms that can pose serious health to you and your family. According to the Centers for Disease Control and Prevention, more than 800 people in the United States have gotten sick from drinking raw milk or eating cheese made from raw milk since 1998.

Raw milk is milk from cows, sheep, or goats that has not been pasteurized to kill harmful bacteria. This raw, unpasteurized milk can carry dangerous bacteria such as Salmonella E. coli, and Listeria, which are responsible for causing numerous food-borne illnesses.

These harmful bacteria can seriously affect the health of anyone who drinks raw milk, or eats foods made from raw milk. However, the bacteria in raw milk can be especially dangerous to pregnant women, children, the elderly, and people with weakened immune systems.

“Pasteurized Milk” Explained

Pasteurization is a process that kills harmful bacteria by heating milk to a specific for a set period of time. First developed by Louis Pasteur in 1864, pasteurization kills harmful organisms responsible for such diseases as listeriosis, typhoid fever, tuberculosis, diphtheria, and brucellosis.

Research shows no meaningful difference in the nutritional values of pasteurized and unpasteurized milk. Pasteurized milk contains low levels of the type of nonpathogenic bacteria that can cause food , so storing your pasteurized milk in the refrigerator is still important.

Raw Milk and Serious Illness

and Advice

  • Symptoms of food-borne illness include:
  • Vomiting, diarrhea, and abdominal pain
  • Flulike symptoms such as fever, headache, and body ache

If you are pregnant, consuming raw milk — or foods made from raw milk, such as Mexican-style cheese like Queso Blanco or Queso Fresco — can harm your baby even if you don’t feel sick.

Raw Milk & Pasteurization: Debunking Milk Myths

While pasteurization has helped provide safe, nutrient-rich milk and cheese for over 120 years, some people continue to believe that pasteurization harms milk and that raw milk is a safe, healthier alternative.

  • Here are some common myths and proven facts about milk and pasteurization:
  • Pasteurizing milk DOES NOT cause lactose intolerance and allergic reactions. Both raw milk and pasteurized milk can cause allergic reactions in people sensitive to milk proteins.
  • Raw milk DOES NOT kill dangerous pathogens by itself.
  • Pasteurization DOES NOT reduce milk’s nutritional value.
  • Pasteurization DOES NOT mean that it is safe to leave milk out of the refrigerator for extended time, particularly after it has been opened.
  • Pasteurization DOES kill harmful bacteria.
  • Pasteurization DOES save lives.
