2000 Multistate Outbreak of E. coli O157:H7 Linked to American Food Group and Supervalu Ground Beef

Minnesota health officials detected a group of people who were infected with the same strain of E.coli O157:H7. Most of the infected Minnesotans had consumed ground beef from SuperValu/Cub Food stores. A total of 42 cases were reported in Minnesota. One case was discovered in Wisconsin and three cases in Ohio. American Food Group supplied beef to the SuperValu/Cub Food Stores and to 178 independent retailers. E.coli O157:H7 was isolated from at least 23 different meat samples during the investigation; four distinct genetic patterns were detected. Nineteen samples matched a strain that had been isolated from ill persons. On December 4, the American Food Group (AFG) recalled the ground beef. USDA records showed that the company had been cited by federal inspectors for a variety of problems, including nine instances where fecal matter had been spotted on the meat and the presence of Salmonella. Even though the Ohio cases had purchased ground beef through a different grocery chain that appeared at first not to be supplied be American Food Group, the CDC concluded through their investigations that the illnesses in Minnesota, Wisconsin, and Ohio were epidemiologically linked.
