The FDA aims to slow the development of antimicrobial resistance. In 2017, the agency worked with drug companies to voluntarily transition medically important antimicrobial drugs for use in the feed or water of food animals from being available over the counter to requiring veterinary oversight and to remove approvals for production uses, such as growth promotion.
The new report indicates that the volume of domestic sales and distribution, by weight, of medically important antimicrobial drugs approved for use in food-producing animals decreased by less than 1% between 2020 and 2021. Compared with 2015, the peak year for sales and distribution, sales and distribution in 2021 were down 38%.
In 2021, the total sales and distribution volume for medically important antimicrobials was about 13 million pounds. An estimated 42% of the volume was estimated to be sold or distributed for use in swine, 41% for use in cattle, 11% for use in turkeys, and 3% for use in chickens, with the remaining 3% intended for use in other species or unknown.
