Some Salmonella Strains Undetected by Traditional Testing Methods
A recent study found room for improvement in Salmonella detection methods in poultry, and provides a framework for a new detection method using advanced technology. Through the use of CRISPR-SeroSeq technology, researchers discovered multiple strains of Salmonella in live bird samples that previously went undetected by traditional testing methods.
The study analyzed national Salmonella monitoring data that was collected from 2016–2020 by the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS). The initial analysis found that, although overall cases of Salmonella contamination in chicken decreased by 2.43 percent over the four-year period, reported cases of salmonellosis remained constant.
