Adams Farm Slaughterhouse E. coli Outbreak
CDC collaborated with public health and regulatory officials in several states and the U.S. Department of Agriculture Food Safety and Inspection Service (USDA-FSIS) to investigate a multistate outbreak of Shiga toxin-producing Escherichia coli O157:H7 (STEC O157:H7) infections.
Eleven people infected with the outbreak strain of STEC O157:H7 were reported from five states – Connecticut, Massachusetts, Pennsylvania, Virginia and West Virginia.
Illnesses started on dates ranging from June 27, 2016 to September 10, 2016. Ill people ranged in age from 1 year to 74, with a median age of 32. Forty-five percent of ill people were female. Seven ill people were hospitalized. One ill person developed hemolytic uremic syndrome, a type of kidney failure, and no deaths were reported.
Epidemiologic, traceback, and laboratory evidence indicated that beef products produced by Adams Farm Slaughterhouse in Athol, Massachusetts, were the likely source of this outbreak.
The Connecticut Department of Public Health collected leftover Adams Farm Slaughterhouse ground beef from an ill person's home and from a restaurant for testing. Test results showed the outbreak strain of STEC O157:H7 in both samples of leftover ground beef.
On September 24, 2016, Adams Farm Slaughterhouse recalled various cuts of beef, veal, and bison products due to possible E. coli O157:H7 contamination. The products originated from animals slaughtered on July 15, 25, and 27, 2016 and August 3, 8, 10, 11, 17, 24, and 26, 2016, and further processed and packed on various dates between July 21 and September 22, 2016. These items were shipped to farmers' markets, retail locations, and restaurants in Massachusetts, Connecticut, and eastern New York. The products may have been shipped to neighboring states. The products subject to recall have establishment number EST. 5497 inside the USDA mark of inspection and include several lot numbers and cuts of meat.
