Annual Report on Antimicrobial Agents Intended for Use in Animals

The OIE Annual Report on Antimicrobial Agents Intended for Use in Animals gathers data provided, on
a voluntarily basis, by the Veterinary Services of OIE Members and non-OIE Members on the use of
antimicrobial agents in animals. The present report has three main sections: (1) interpretation of the
overall findings of the sixth annual data collection round, reporting results at global and regional levels;
(2) detailed analyses for 2018, with regard to the total amount of antimicrobial agents intended for
use in animals, as well as normalised using an estimated animal biomass indicator; (3) trend analyses
for 2016 to 2018, after adjustment to the estimated animal biomass indicator.

The use of antimicrobials in animals across the world has shown an overall decrease of 27% between 2016 and 2018, according to the data reported to the World Organisation for Animal Health (WOAH, founded as OIE).
