Objective
1. Develop reliable and reproducible challenge models with Salmonella and Campylobacter for use in accurately developing, evaluating, and validating processes for reducing pathogen load using various chemical sanitizers. 2. Develop, evaluate, and validate current and novel chemicals, operational protocols, and sampling methodologies used during poultry production and processing of broilers for the reduction and/or control of foodborne pathogens. 2.1. Assess the ability of commercial and novel chemical sanitizers to reduce or eliminate Salmonella, Campylobacter, and Pseudomonas species from inoculated broiler carcasses and parts. 2.2. Examine the effectiveness of chemical sanitizers applied to carcasses before defeathering or before chilling to reduce contamination by Salmonella and Campylobacter carcasses in postchill carcasses. 2.3. Formulate novel microbicidal surfactants from mixtures of medium-chain fatty acids (MCFA) and organic acids (OA) to be used as sanitizers to significantly reduce microbial contamination during poultry processing. 3. Identify and evaluate risk factors in the production, management, transportation, or processing that impact bird/egg contamination with foodborne pathogens and develop intervention strategies to control pathogens in the absence of antibiotics. 3.1. Assess the ability of chemical sanitizers to reduce contamination of inoculated, fertile eggs by Salmonella. 3.2. Identify and evaluate risk factors in the production, management, transportation, or processing that impact broiler contamination with foodborne pathogens and develop intervention strategies to control pathogens in the absence of antibiotics. 4. Determine the extrinsic factors that impact the survival and attachment of microorganisms including evaluating media and growth factors. Develop and validate new improved technologies to isolate and propagate foodborne pathogens. 4.1. Evaluate media and growth factors and use the findings to develop new, improved technologies for the isolation and propagation of Campylobacter. 4.2. Assess accuracy of current laboratory methods in recovering Salmonella from poultry, animal feeds, and dry environmental samples with fermentable substrates available and development of a more efficient pre-enrichment media.
