Dr. Bourassa’s research focuses on poultry processing, microbiology, and food safety. Her poultry processing research topic areas have included stunning and animal welfare, the effects primary processing parameters on carcass microbiology, carcass sampling methods for foodborne pathogens, as well as the effects of on farm interventions on fully processed carcasses.
Dr. Bourassa’s extension program includes support of the Alabama poultry industry in the area of poultry processing by providing education in essential areas such as stunning welfare, food safety, and regulatory compliance. Bourassa’s program also addresses poultry processing and food safety for the public and youth through programs including 4-H and FFA.
