The average annual number of outbreaks due to drinking raw (unpasteurized) milk have more than quadrupled – from an average of three outbreaks per year during 1993-2006 to 13 per year during 2007-2012. Overall, there were 81 outbreaks in 26 states from 2007 to 2012.
As more states have allowed the legal sale of raw milk, there has been a rapid increase in the number of raw milk-associated outbreaks.The outbreaks, which accounted for about 5 percent of all food-borne outbreaks with a known food source, sickened nearly 1,000 people and sent 73 to the hospital. More than 80 percent of the outbreaks occurred in states where selling raw milk was legal.
