Organic Pastures Dairy Unpasteurized, Raw Milk 2011

Raw milk products produced by Organic Pastures Dairy were recalled and quarantined, except for cheese aged more than 60 days, by the state of California after five children were infected with the same strain of E. coli O157:H7 and drinking Organic Pastures Dairy raw milk. The children were residents of Contra Costa, Kings, Sacramento, and San Diego counties. The only common food exposure was the unpasteurized raw milk. Laboratory sampling of milk failed to detect E. coli O157:H7, however the outbreak strain of E. coli O157:H7 was recovered from environmental samples collected from the milking area. The recall was initially ordered strictly on the basis of the epidemiologic findings of the California Department of Public Health. In 2006, Organic Pastures Dairy was implicated in an outbreak of a different strain of E. coli O157:H7.
