Shiga toxin-producing E. coli (STEC), including E. coli O157:H7, is on California's Big 6 reportable list. Which food is the CLASSIC outbreak vehicle for STEC and what is the relevant cooking control?
Explanation
California Retail Food Code HSC §113949.1 lists STEC (Shiga toxin-producing E. coli, including the well-known serotype O157:H7) as a Big 6 reportable pathogen. The classic outbreak vehicle is undercooked GROUND BEEF — the 1993 Jack-in-the-Box outbreak (4 children died, 700+ sickened) drove the federal switch to mandatory 155°F cooking for ground beef. Cattle are the primary reservoir, with the organism present in their intestines and shed in feces; ground beef pools surface-contaminated trim from many animals, distributing surface bacteria into the geometric center of every patty. Other documented vehicles: raw leafy greens contaminated by cattle-feces runoff (multiple romaine outbreaks 2017-2020), unpasteurized milk and juice, raw flour, mechanically tenderized whole-muscle beef, and venison. Cooking control under HSC §114004 is 155°F for 17 seconds (or equivalent time-temperature combination) in the center of the ground product. Option A is wrong; pasteurized dairy is the SAFE product. Option C describes poultry/Salmonella controls. Option D describes a temperature combination that does not apply to STEC. STEC's hemolytic uremic syndrome (HUS) is the leading cause of acute kidney failure in U.S. children.
