Recent Paper on Whole Genome Sequencing and Salmonella Outbreaks
Multistate foodborne outbreaks of Salmonella infections associated with chicken can be challenging to investigate due to high consumption rates of chicken and the large number of brands. After a 2014 outbreak of Salmonella Heidelberg, researchers conducted a follow-up analysis by sequencing the genome on some of the outbreak isolates. The findings provided further evidence that chicken from a particular producer was the source of the outbreak. CDC, the U.S. Department of Agriculture’s Food Safety and Inspection Service, and state and local health departments published this research in a new article in the Journal of Food Protection. The article highlights how whole genome sequencing can be used with epidemiologic and traceback evidence to more confidently identify chicken sources of foodborne outbreaks.
