University of California Collaborates with Georgia Tech for Poultry and Pork Processing Study

When University of California San Francisco (UCSF) officials were contracted by the U.S. Department of Agriculture (USDA) to conduct research on line speeds at pork and poultry processing facilities, they knew exactly who to ask for additional support: researchers from the Safety, Health, and Environmental Services (SHES) division at Georgia Tech.

Partnership for Research

UCSF needed a partner with specific scientific expertise regarding employee exposure to a chemical used in pork processing. SHES’ prior working relationship with UCSF proved beneficial, leading to a collaborative effort. Dr. Jenny Houlroyd, the manager of occupational health services at SHES, highlighted the importance of leveraging expertise across institutions.

Study Parameters

The study focused on the impact of increased poultry and swine evisceration line speeds on worker safety. Moreover, it examined the potential increase in worker exposure to peracetic acid with faster processing speeds. The research aimed to measure exposure levels accurately.

SHES’ Role

Starting in July 2024, SHES researchers conducted field research at six pork processing plants across the U.S. Over 11 weeks, the team collected data on peracetic acid exposure. Despite safety restrictions, the team ensured accurate sampling methods.

Importance of Worker Interviews

While not mandatory, SHES conducted worker interviews to gain insights into ergonomic issues and musculoskeletal disorders. This approach not only benefitted the study but also showed concern for workers’ well-being.

Study Results

The study findings pointed to an increased injury risk due to faster line speeds, but mitigation measures were identified. However, the results regarding peracetic acid exposure were inconclusive, warranting further research. Dr. Houlroyd commended the team’s dedication and compassion throughout the study.
