Technical Abstract: Foodborne pathogens pose significant health risks to consumers. The leading causes of foodborne illness associated with poultry consumption are Campylobacter and Salmonella contamination. One strategy to reduce these enteric pathogenic microflora is the administration of nonpathogenic bacterial cultures to poultry, known as competitive exclusion (CE). Although current CE cultures have efficacy against enteric Salmonella colonization, these cultures have little if any consistent efficacy against Campylobacter. Recently, using in vitro selection techniques we have identified lactic acid bacteria (LABS) with potential anti-Campylobacter activity. To evaluate the ability of these LABS to reduce Campylobacter colonization in turkeys, neonatal poults were dosed on the day of hatch with various combinations of LABS and/or the commercial organic acids (OA) treatment, Performax® (n=10poults/treatment). Three days following LABS treatment, Campylobacter(100 to 1,000) was administered to poults by oral gavage. On day 10, all poults were sacrificed and cecal contents enumerated for Campylobacter. In two separate trials, at best, there was a 1 log reduction with either LABS or OA, alone. However, when LABS and OA were used together, there was up to a 3 to 4 log reduction in cecal Campylobacter content compared to controls. These results indicate that it is possible to significantly reduce Campylobacter concentrations in poults with the use of selective bacteria in combination with OA. The enhanced efficacy of our LAB cultures in the presence of OA may be due to OA's ability to favorably alter the enteric environment promoting LAB colonization.
