FDA Launches Interactive Summary of Biomass-Adjusted Antimicrobial Sales Data in Food Animals

Dec 06, 2022

The U.S. Food and Drug Administration launched an Interactive Summary of Biomass-Adjusted Antimicrobial Sales Data.

The display applies a biomass denominator to adjust existing annual antimicrobial sales and distribution data for medically important antimicrobial drugs sold or distributed for use in food-producing animals (cattle, swine, chickens, and turkeys) in the United States for years 2016 to 2020. Animal biomass is defined as the population of a given livestock species in the U.S. multiplied by the average weight of that species. In this method, a biomass denominator adjusts annual antimicrobial sales data to account for the size of the population of a given livestock species in the U.S. potentially being treated with those drugs.

See the interactive summary at https://www.fda.gov/animal-veterinary/antimicrobial-resistance/biomass-adjusted-antimicrobial-sales-and-distribution-data-food-producing-animals-interactive.

The interactive summary allows users to customize data visualizations using criteria such as antimicrobial drug class, species, and year.

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.
