Federal legislation prohibits the sale of raw milk anywhere in Canada because our bodies are not used to some of the bacteria that exists naturally in milk. Pasteurization (the process of heating milk up to a very hot temperature for short amount of time), eliminates some of that bacteria that may cause people to get sick. Scientific research has demonstrated a long time ago that pasteurization does not alter the high nutritional qualities of milk.
The pathogenic microorganisms currently most often found in raw milk that are responsible for food poisoning include: Salmonella, E. coli 0157:H7, Campylobacter jejuni, and Listeria monocytogenes. These bacteria can cause health problems ranging from ordinary headaches to abdominal pains, diarrhea, nausea and vomiting. In extreme cases, abortions and death can result, as reported by scientific literature throughout the world.
