Dr. Dianna Bourassa is an Associate Professor and Extension Specialist specializing in poultry processing, animal welfare, and food safety. She leads an applied research program focused on improving slaughter technologies, reducing Salmonella and Campylobacter, and enhancing meat quality. Her work has produced more than 70 peer‑reviewed publications, secured over $13M in funding, and directly informed commercial practices across the U.S. poultry industry. Through extensive Extension programming, including HACCP training, newsletters, and processor workshops, she provides science‑based solutions to stakeholders and advances poultry safety and welfare from farm to processing.
Dr. Dianna Bourassa’s research improves poultry processing by advancing science‑based practices that enhance bird welfare and reduce foodborne pathogens. Her work provides evidence that helps processors refine stunning systems, strengthen antimicrobial strategies, and optimize steps that influence meat quality. These findings have informed commercial decision‑making, supported updates to testing and monitoring practices, and guided companies in adopting more effective, welfare‑aligned technologies. Her applied research is widely used across the poultry industry to improve efficiency, product safety, and overall processing outcomes.
Dr. Dianna Bourassa leads extensive Extension programs that support poultry processors, farmers, and public audiences with practical, science‑based guidance. She developed widely used programs,including HACCP Roundtables, euthanasia training, and poultry processing workshops that help industry professionals improve food safety, animal welfare, and processing efficiency. Her monthly newsletters, applied research, and one‑on‑one technical support directly inform industry practices across Alabama and beyond. She also engages youth and community members through 4‑H, FFA, and small‑flock education, expanding access to safe and humane poultry production knowledge.
