Raw milk is, according to the U.S. Centers for Disease Control, in a report of a Salmonella Typhimurium outbreak associated with raw milk and cheese consumption in Pennsylvania in 2007, a well-documented source of infections from Salmonella, Escherichia coli O157:H7, Campylobacter, Listeria, Mycobacterium bovis, and other pathogens. In 1938, before widespread adoption of milk pasteurization in the United States, an estimated 25% of all foodborne and waterborne outbreaks of disease were associated with milk.
By 2001, the percentage of such outbreaks associated with milk was estimated at <1%. During 1998–2005, a total of 45 outbreaks of foodborne illness were reported to CDC in which unpasteurized milk (or cheese suspected to have been made from unpasteurized milk) was implicated. These outbreaks accounted for 1,007 illnesses, 104 hospitalizations, and two deaths (CDC, unpublished data, 2007). Because not all cases of foodborne illness are recognized and reported, the actual number of illnesses associated with unpasteurized milk likely is greater.
Unsubstantiated claims of health benefits of raw milk for infants and children are particularly concerning for caregivers because infants and children are dependent on their caregivers to make safe dietary decisions for them. Sixteen of the 29 ill persons in this outbreak were aged <7 years.
Adults, do what you like, but keep your kids out of the raw milk roulette.
