Federal data released last week show that sales of medically important antimicrobials used in food-producing animals in the U.S. increased by 3 percent in 2013 and by 20 percent between 2009 and 2013.
The Food and Drug Administration’s 2013 Summary Report of the information animal drug sponsors are required by the Animal Drug User Fee Act (ADUFA) to report every year reflects data from the year prior to the agency’s announcement of its judicious use strategy for these antimicrobials.
In 2013, sales of medically important antimicrobials accounted for 62 percent of all antimicrobials approved for use in food animals. Of these sales, tetracyclines accounted for 71 percent, penicillins for 9 percent, macrolides for 6 percent, sulfonamides for 4 percent, aminoglycosides for 3 percent, lincosamides for 3 percent, and cephalosporins for less than 1 percent.
