• The domestic sales and distribution of medically important antimicrobials approved for use in food- producing animals that are sold OTC decreased from 8,000,326 kg to 271,280 kg from 2016 through 2017 as a result of the implementation of GFI #213.

  • Tetracyclines accounted for 64 %, penicillins for 12%, macrolides for 8%, sulfas for 5%, aminoglycosides for 5 %, lincosamides for 3%, and cephalosporins and flu oroquinolones each for less than 1%.
  • An estimated 42 % was intended for use in cattle, an estimated 36% intended for use in swine, an estimated 12 % intended for use in turkeys , an estimated 5% intended for use in chickens, and an estimat ed 5% intended for use in other species/unknown.
  • An estimated 80% of cephalosporins, 72 % of sulfas, 48 % of aminoglycocides, and 44% of tetracyclines were intended for use in cattle . An estimated 84% of lincosamides and 40% of macrolides were intended for use in swine. An estimated 6 1% of penicillins were intended for use in turkey s
