Carneco and Sam’s Club E. coli Outbreak
In August of 2004, the United States Department of Agriculture (USDA) Food Safety and Inspection Service (FSIS) announced that Carneco Foods was recalling 497,000 pounds of frozen ground beef patties due to E. coli contamination. The hamburger patties had been identified as the source of an E. coli O157:H7 outbreak among Minnesota residents who purchased the product at Sam’s Club stores under the brand name “Northern Plains.”
By the time public health officials had concluded their investigation, they identified five Minnesotans and one Wisconsinite who tested positive for a genetically indistinguishable strain of E. coli O157:H7. The patties were purchased in White Bear Lake and Eagan, Minnesota, and in Waukesha, Wisconsin.
