UCSF, Georgia Tech SHES, and UC Berkeley Lead Pioneering Research on Line Speed and Worker Safety in Pork and Poultry Processing Facilities
May 9, 2025
At ChemDAQ, protecting frontline workers from chemical exposure is our mission. That’s why we proudly recognize the exceptional work by the University of California San Francisco (UCSF), Georgia Tech’s Safety, Health, and Environmental Services (SHES) division, and UC Berkeley in conducting one of the most comprehensive studies to date on line speeds in pork and poultry processing facilities.
This USDA-commissioned research initiative sought to determine whether increased evisceration line speeds negatively affect worker safety. In a collaborative approach, UCSF brought in leading experts from Georgia Tech and the UC system to tackle this challenge with both scientific rigor and deep compassion for the workers involved.
Georgia Tech SHES played a crucial role by assessing worker exposure to peracetic acid (PAA), a chemical widely used in protein processing to reduce bacterial contamination. Through wearable sampling, detailed site analysis, and in-depth worker interviews, the SHES team provided valuable insights into how chemical exposure may or may not change under increased line speeds.
UC Berkeley contributed significantly to the broader data collection and analysis efforts, helping to ensure the study addressed both chemical and ergonomic concerns. Their participation in this cross-university collaboration highlights the power of merging institutional expertise to serve public health and worker safety.
While the study confirmed a heightened risk of injury with faster line speeds, the findings on peracetic acid exposure were more subtle. One facility showed increased exposure, but the trend was not consistent across all plants, suggesting the need for further monitoring and additional research, a call to action that we fully support.
One recommendation from the study is that “All poultry processing establishments using PAA should implement an industrial hygiene program to maintain worker exposures below the ACGIH 0.4 ppm STEL.”
At ChemDAQ, we see this study as a major step forward. It affirms the importance of data-driven decision-making and underscores why continous, real-time chemical monitoring in food processing environments matters more than ever. In support of this ongoing effort, ChemDAQ can assist facilities by offering educational resources, conducting PAA safety assessments, providing monitoring equipment and training, and delivering abatement solutions to mitigate risk and safeguard workers.
We extend our deepest appreciation to the researchers and field staff who committed themselves to this effort.
Thank you for advocating for safer, smarter food processing environments. ChemDAQ is proud to support and align with your mission.
