During Fiscal Year 2020, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) investigated 12 different outbreaks. The outbreaks included about 400 illnesses and more than 150 hospitalizations.
The most common pathogens involved were Salmonella (50 percent), followed by STEC (33 percent), with beef (41.7 percent) being the most common food product of interest. The six Salmonella outbreaks investigated included five serotypes: Dublin, Enteritidis, I 4,[5],12:i:-, Thompson, and Typhimurium. All four STEC outbreaks were caused by serogroup O157:H7 (see Figures 1 and 2).
