| Title: | Data Acquisition and Modeling for Poultry Food Safety |
|---|---|
| Objective: | Salmonella bacteria are a leading cause of foodborne illness and they are often isolated from poultry. There are more than 2,300 serotypes of Salmonella, yet only about 50 are responsible for most cases of foodborne illness. Thus, not all Salmonella serotypes that contaminate poultry pose the same risk of foodborne illness. In the proposed project, predictive microbiology models for contamination, growth and survival of Salmonella serotypes on chicken parts will be developed and linked to form an exposure assessment (EA) model that predicts changes in incidence and number of Salmonella serotypes on chicken parts produced by different farm-to-table scenarios. The EA model will predict consumer exposure to Salmonella serotypes that survive cooking of chicken parts and that cross-contaminate cooked chicken parts during serving. The EA model will be designed to evaluate effects of interventions on consumer exposure to Salmonella serotypes of chicken origin. The intervention evaluated in this project will be a plastic chicken house floor that has potential to reduce Salmonella serotypes entering the processing plant and surviving on chicken parts after final processing. Together, data acquired and models developed in this project will provide the sound science and tools needed to consider Salmonella serotype; Salmonella serotype number and post-processing risk factors in the evaluation of chicken safety at the processing plant. |
| More Info: | Attainment of the objectives will provide data and models needed to consider Salmonella serotype; Salmonella serotype number and post-processing risk factors in the assessment of chicken safety at the processing plant. This will benefit public health by providing a more holistic approach for proper identification of safe and unsafe chicken at the processing plant, which is needed to maximize the public health benefit of chicken by ensuring both its safety and consumption. |
