No. FDA and other health agencies such as the Centers for Disease Control and organizations such as the American Academy of Pediatrics agree that raw milk is unsafe because it can contain disease-causing pathogens, including:
- Enterotoxigenic Staphylococcus aureus
- Campylobacter jejuni
- Salmonella species
- E. coli
- Listeria monocytogenes
- Mycobacterium tuberculosis
- Mycobacterium bovis
- Brucella species
- Coxiella Burnetii
- Yersinia enterocolitica
Illnesses caused by these bacteria can be especially problematic for infants, young children, the elderly, and the immunocompromised. One complication that can arise as a result of infection with E. coli O157:H7 is hemolytic uremic syndrome (HUS), which can cause acute renal failure, especially in the very young or the elderly.
Based on CDC data, literature, and state and local reports, FDA compiled a list of outbreaks that occurred in the U.S. from 1987 to September 2010. During this period, there were at least 133 outbreaks due to the consumption of raw milk and raw milk products. These outbreaks caused 2,659 cases of illnesses, 269 hospitalizations, 3 deaths, 6 stillbirths and 2 miscarriages. Because not all cases of foodborne illness are recognized and reported, the actual number of illnesses associated with raw milk likely is greater.
Symptoms of illness caused by consuming raw milk include: vomiting, diarrhea, abdominal pain, fever, headache, and body ache. Most healthy people will recover from illness caused by harmful bacteria in raw milk - or in foods made with raw milk - within a short period of time, however, some individuals can develop symptoms that are chronic, severe, or even life threatening.
If you or someone you know becomes ill after consuming raw milk - or, if you are pregnant and think you could have consumed contaminated raw milk or cheese made from raw milk - see a doctor or healthcare provider immediately.
No. As a science-based regulatory agency, the FDA looks to the scientific literature for information on benefits and risks associated with raw milk. While the perceived nutritional and health benefits of raw milk consumption have not been scientifically substantiated, the health risks are clear. Please see http://www.fda.gov/Food/FoodborneIllnessContaminants/BuyStoreServeSafeFood/ucm247991.htm for more information.
Not in interstate commerce. Pasteurization of milk was adopted decades ago as a basic public health measure to kill dangerous bacteria and largely eliminate the risk of getting sick from one of the most important staples of the American diet. In 1987, the FDA issued a regulation prohibiting the interstate sale of raw milk. However, some states do permit the intrastate (within the borders) sale of raw milk intended for human consumption.
Pasteurization is a process that kills harmful bacteria by heating milk to a specific temperature for a set period of time. Pasteurization kills the bacteria responsible for diseases such as listeriosis, salmonellosis, campylobacteriosis, typhoid fever, tuberculosis, diphtheria, and brucellosis, as well as other bacteria. However, pasteurized milk still contains low levels of the type of nonpathogenic bacteria that can cause food to spoil, so it is important to keep pasteurized milk refrigerated.
Research shows no meaningful difference between the nutrient content of pasteurized and unpasteurized milk.
No. The milk proteins which cause allergic reactions in dairy-sensitive people are present in both raw milk and pasteurized milk.
No. Lactose intolerance is due to an insufficient production in the body of the enzyme needed to break down lactose, beta-galactosidase. Lactose is present in both raw milk and pasteurized milk at the same concentration. Pasteurization does not impact the concentration of lactose.
No, it does not. In fact, raw milk potentially harbors a wide range of dangerous pathogens that can cause illness.
There is no scientific evidence to demonstrate that raw milk has any effect on illness or allergies.
