Salmonella is commonly found in ground beef and, in fact, caused an illness outbreak in January 2013 in six states. Salmonella is an especially difficult bacteria for food safety experts to address because it is so prevalent in almost all food sources.
Recognizing that we need more information about the prevalence of salmonella in ground beef to better prevent food-borne illness, FSIS is “super-sizing” our pathogen testing program to include salmonella every time our laboratories test for E. coli in samples of ground beef and ground beef sources.
Because the samples taken for E. coli testing are much larger than those we have taken in the past for salmonella, there is a higher likelihood that we will be able to detect the bacteria if it is present.
Once FSIS has collected enough data about the prevalence of salmonella in ground beef, we will create a new standard to encourage ground beef processors to strengthen their salmonella controls, resulting in safer products and fewer foodborne illnesses.
The data collection process will take some time, but it is critical that the new standard is supported by meaningful data. Of course, we will continue to analyze any positive samples for multi-drug resistance and specific serotypes to determine whether they are contributing to human illnesses.
Salmonella is the most urgent issue facing FSIS when it comes to protecting consumers, and it is why we developed our Salmonella Action Plan. This plan details our strategy for reducing the number of salmonella-related illnesses, and this enhancement to our sampling and testing programs is part of that comprehensive effort.
Another part of our war on salmonella is encouraging consumers to take steps to protect themselves from illnesses, including cooking all ground beef to 160 °F (poultry should be cooked to 165 °F).
