Hudson Foods Ground Beef Patties and Burgers 1997

An outbreak of Escherichia coli O157:H7 infections associated with eating a nationally distributed commercial brand of frozen beef patties and burgers was detected in Colorado. Genetic fingerprinting of the E.coli O157:H7 isolated from the ill persons showed high, genetic similarity among the strains. Eleven (79%) of 14 patients reported eating frozen, pre-formed, ground beef patties, or burgers, at least once during the seven day period preceding illness onset; eight specifically recalled eating Hudson Foods brand product, and three, who could not recall a specific brand name, identified package labeling consistent with Hudson Foods brand. Hudson Foods beef burgers collected from the freezers of two of the 15 patients bore the identical lot number; both yielded E. coli O157:H7, upon culture, that was indistinguishable from the outbreak strain. The product was recalled nationwide. Burger King Restaurants were a major customer for this hamburger.
