Escherichia coli 0157:H7 infections in children associated with raw milk and raw colostrum from cows--California, 2006.
On September 18, 2006, the California Department of Public Health (CDPH) was notified of two children hospitalized with hemolytic uremic syndrome (HUS). One of the patients had culture-confirmed Escherichia coli O157:H7 infection, and both patients had consumed raw (unpasteurized) cow milk in the week before illness onset. Four additional cases of E. coli O157:H7 infection in children who had consumed raw cow milk or raw cow colostrum produced by the same dairy were identified during the following 3 weeks. In California, intrastate sale of raw milk and raw colostrum is legal and regulated. This report summarizes the investigation of these cases by CDPH, the California Department of Food and Agriculture (CDFA), and four local health departments and subsequent actions to prevent illnesses. As a result of this and other outbreaks, California enacted legislation (AB 1735), which took effect January 1, 2008, setting a limit of 10 coliforms/mL for raw milk sold to consumers. Raw milk in several forms, including colostrum, remains a vehicle of serious enteric infections, even if the sale of raw milk is regulated.
