USDA Wants To Update Poultry Production To Combat Foodborne Illnesses

USDA Wants To Update Poultry Production To Combat Foodborne Illnesses

The U.S. Department of Agriculture on Friday proposed sweeping changes in the way chicken and turkey meat is processed that are intended to reduce illnesses from food contamination but could require meat companies to make extensive changes to their operations.

Despite decades of efforts to try and reduce illnesses caused by salmonella in food, more than 1 million people are sickened every year and nearly a fourth of those cases come from turkey and chicken meat.

As it stands, consumers bear much of the responsibility for avoiding illness from raw poultry by handling it carefully in the kitchen — following the usual advice to not wash raw chicken or turkey (it spreads the bacteria), using separate utensils when preparing meat and cooking to 165 degrees. The USDA’s Food Safety and Inspection Service wants to do something about it by starting with the farmers that raise the birds and following through the processing plant where the meat is made.

Video: Porcine Gut Models in Nutrition Research - Dr. Li-Hsuan Chen



In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Li-Hsuan Chen, postdoc researcher at Aarhus University, discusses how porcine intestinal cell lines and organoids can help study the impact of nutrition on gut health. He explains how in vivo piglet trials identify diet-driven shifts in microbiota and metabolites, while in vitro models allow researchers to test specific metabolites, barrier function, immune markers, and future organ-on-chip systems before moving back to animal studies. Listen now on all major platforms!

"In vitro models can reduce early animal use by helping researchers screen nutritional candidates before moving back to in vivo trials."

Meet the guest: Dr. Li-Hsuan Chen / li-hsuan-chen-9a95a7279 is a postdoc researcher at Aarhus University in Denmark. Research focuses on porcine gut health, host-microbe interactions, cell lines, and organoids, with PhD work at Aarhus University studying how dietary protein and amino acid levels shape gut microbiota, microbial metabolites, and intestinal epithelial responses.
