A totalof 549 swabs were cultured and the rate of isolation was 0.7% (four of 549positive for Salmonella). Positive swabs were recovered from threetrucks for a recovery rate of 13.6%. Feed was submitted for 17 of 22 trucksand Salmonella was recovered from four of 17 samples (23.5%). However,positive swabs and feed samples only matched for two trucks. No trucks hadbeen used to transport livestock within the past 30 days nor were any truckscleaned or disinfected between loads.Implications: While sample prevalence of Salmonella infeed trucks is low (0.7%), the overall contamination rate for feed trucksis much higher (22.7%). The presence of positive feed samples suggests thatfeed could be a source of Salmonella contamination for swine. ER -
