E. coli contamination is most likely in ground beef because the grinding process distributes any bacteria from the surface throughout the meat. In whole cuts, most bacteria are on the exterior, so proper cooking can kill them if you’re only heating the outer layer. But when meat is ground, those surface bacteria are mixed in, so undercooking can allow the bacteria to survive inside the product. This is why ground beef is the classic source linked to E. coli outbreaks. Ground turkey can carry pathogens too, but the strongest association with E. coli outbreaks is beef. Rice and milk have other common safety concerns, such as Bacillus cereus or spoilage, or contamination from raw milk, respectively, rather than E. coli being the primary risk. Always cook ground beef to a safe internal temperature and prevent cross-contamination.
