Interpretive Summary:

Technical Abstract: Two cohorts of finishing pigs were followed from nursery age to slaughter to examine the role of All-In-All-Out vs. continuous flow production in food safety microbial transmission. Additionally these cohorts were followed into the abattoir to determine the effect of management on microbial isolation rates. There was no difference in the on-farm and in-plant isolation rates for Salmonella spp. On-farm management factors did not affect in-plant isolation rates. Although few animals were culture positive on-farm 20, 40% of gut-associated tissues were positive in-plant. On-farm fecal cultures and mixed ELISA results were not good predictors of the Salmonella isolation rates in-plant. Although Salmonella on-farm isolation rates were numerically higher in North Carolina, the same relationships existed in these diverse geographic locations.
