IMPACT and CONTRIBUTION
The NCSU Poultry Processing program encompasses live bird production through consumption of cooked meat. Every input into the live bird potentially affects the end product, including meat quality and food safety. Processing and product handling may also affect safety and quality. Therefore muscle physiology, animal welfare, genetics, microbiology, sensory analysis, packaging, sales, marketing, distribution, and regulatory agency interactions are all areas of interest. Both technical and business aspects of poultry processing are addressed.
Evaluating and reducing Campylobacter, Salmonella, E. coli, and total aerobes on broiler and turkey live birds, hatching eggs, carcasses, meat,chilling water, and packaging materials.
Study and improvement of broiler, turkey, and duck meat quality as affected by production method, genetic strain, or diet, and measured by colorimetry, objective shear, and taste panel analysis.
