The pasteurization of milk 100 years ago is still heralded by many as a major advancement in food safety. Although there are people who support raw milk, the CDC estimates that the unpasteurized (raw) milk is 150 times more likely to cause foodborne illness and results in 13 times more hospitalizations than pasteurized milk. Raw milk can carry Salmonella, E. coli, and Listeria, which is a serious infection that most often affects older adults, pregnant women, newborns, and adults with weakened immune systems. Symptoms of listeriosis include muscles aches, headache, and gastrointestinal issues. See our list of five non-dairy milk alternatives.
