Chicken has been shown to be one source of salmonellae that causes human illness. Competitive exclusion is a process that matures the young chickens intestinal tract thereby preventing salmonella contamination. This process was shown to be a useful approach for reducing salmonellae contamination of market poultry, hence reducing human exposure and human illness. Technical Abstract: A series of paired house studies were conducted in Puerto Rico, Arkansas, Alabama and Georgia to determine the efficacy of MSC(TM) to eliminate or reduce salmonellae in broiler chickens. Randomly designated chicks were treated twice with MSC(TM). First hicks were sprayed with an MSC solution using a spray vaccination cabinet in the hatchery. Chicks then received MSC in the first drinking water at the growing house. Chicks were grown in paired houses that were designed, equipped and managed in similar manners. After grow-out chicks were processed in commercial plants according to industry standards. MSC treated carcasses sampled after final washer and before the final chiller had significantly (P=.05) less salmonellae than untreated control birds. Overall, these data confirm a highly significant reduction in the salmonellae found on processed broiler carcasses treated with MSC. The use of MSC may be a useful approach for control of salmonellae in commercial poultry. |
