Abstract
Recently, the prevalence of backyard chickens and of live poultry-associated salmonellosis has increased across the US. The National Poultry Improvement Plan’s Salmonella monitoring program (NPIP-SMP) exists to reduce Salmonella enterica levels in hatcheries selling to hobby farmers. Our goal was to determine the prevalence of S. enterica in chicks in Vermont and determine whether the NPIP-SMP was effective. 82/203 (40.4%) chick samples contained S. enterica. NPIP-SMP chick samples were more frequently positive for S. enterica (50.9%) than samples from non-participating hatcheries (27.8%; Chi-squared test, p <0.01). Consequently, purchasing chicks from NPIP-SMP hatcheries does not reduce salmonellosis risk for poultry owners.
