No Silver Bullet For Removing Pathogens In Poultry

“ There is no silver bullet for removing pathogens from the safest food supply on the planet ,” said Dr. Dan Zelenka , director of s tatistics, Tyson Foods, Inc., at USPOULTRY’s 201 4 Poultry Processor Workshop held at the Embassy Suites Centennial Olympic Park in Atlanta, Ga . During his presentation on Raw Parts Intervention for Reducing Contamination , Dr. Zelenka noted that the industry has much experience in producing safe and wholesome products, and interventions are an important part of the system that produces these products.

He rev iewed various types of interventions and stressed that USDA will continue pressuring the poultry industry to lower pathogen contamination rates, remarking that it is the industry’s responsibility to do this in the most cost effective manner possible.

Dr . Yi Liang, associate professor and extension e ngineer, University of Arkansas, provided an Energy Cost Savings Analysis in Poultry Processing . Liang reviewed the major energy users in poultry processing, including process heating, process cooling, compressed air and facility lighting, and discussed various opportunities to improve energy efficiency in several areas .

She stressed the importance of meas uring by remarking, “If you can’t measure it, you can’t manage it.” This research was funded by the USPOULTRY Foundation.

Dr. Troy Rowan sits down with CLEAR Conversations host, Tracy Sellers. Dr. Rowan was a featured speaker at the 2025 State of the Science Summit at UC Davis. The event will return next year on June 16-18, 2026, continuing its focus on advancing livestock methane research and collaborative solutions.

Rowan, now an assistant professor at the University of Tennessee Institute of Agriculture, grew up surrounded by cattle on his family’s Charolais operation in Iowa. His family has been farming and ranching there for more than a century — long enough for the rhythms of agriculture to get in his blood.
