Technical Abstract: Salmonella is represented by >2600 serovars that can exhibit different phenotypes, including virulence, antimicrobial resistance, and host restriction. Poultry is a major Salmonella reservoir, but current culture-based detection methodology is limited: 1) it only identifies the most abundant serovars and background serovars remain undetected, 2) different enrichment procedures may introduce bias, and 3) a two-minute carcass rinse prior to pre-enrichment is insufficient to release all Salmonella present. The inability to assess serovar diversity means that those posing a greater public health risk may be masked by abundant serovars such as ser. Kentucky, which is rarely associated with illness in the U.S., but is the top serovar isolated from broilers.
