Two studies were conducted to evaluate the effects of an abrasive rinse on the recovery of bacteria from broiler carcasses. The purpose of experiment one was to determine if there was a difference in aerobic bacteria, coliform, and Escherichia coli recovery from whole carcasses rinsed with peptone and those rinsed with peptone plus sand. A secondary objective was to determine if shaking duration became a significant factor when utilizing sand. Experiment two was conducted to determine the effects of added sand on the recovery of Salmonella and Campylobacter from half carcass rinses. Aerobic bacteria, coliform and E. coli levels recovered from the peptone plus sand rinses were significantly higher (P<0.05) than those recovered from the peptone rinses. Shaking duration was not a significant factor when rinsing with peptone and sand. There was no significant difference in Salmonella or Campylobacter recovered from the peptone and peptone plus sand rinses.
