Antimicrobial drug use can contribute to the emergence of antimicrobial drug-resistant organisms.
Scientifically sound data on antimicrobial use are vital for understanding the diseases that necessitate their use, the drivers of antibiotic resistance, and for assessing interventions designed to slow its spread.

In 2016, FDA awarded funds in the form of cooperative agreements to support pilot projects for the collection of farm-level antimicrobial use data in animal agriculture. These funded data collection efforts are intended to provide needed information on antimicrobial use practices in various animal production settings and to inform the development of long-term strategies for collecting and reporting such data in a sustainable and nationally representative manner.

Latest Release

We are proud to release updated on-farm antimicrobial use data for U.S. turkeys, broiler chickens, and, for the first time, layer chickens. Data for turkeys and broiler chickens span years 2013-2021 and represent 70% and 80% of annual U.S. production respectively. Data for layer chickens span years 2016-2021 and represent 45% of annual U.S. table egg production.

This project represents ongoing partnerships with the FDA, USDA-APHIS, U.S. Poultry & Egg Association, National Chicken Council, National Turkey Federation, United Egg Producers as well as layer, broiler chicken and turkey companies of the U.S.

Mindwalk Consulting Group, LLC manages the collection of antimicrobial use data for the broiler chicken, layer chicken, and turkey commodities. We collaborate with other groups on the collection of data for pigs and beef and dairy cattle.
