Systems for quantification of antimicrobial usage

Antimicrobial usage (AMU) is the main driver for the selection and spread of antimicrobial resistance (AMR), which is considered one of the major health challenges in human and veterinary medicine. In order to obtain a reduced and more appropriate AMU in animals, and ultimately lowered levels of AMR, detailed knowledge of AMU in different countries, sectors, farms, etc. is key. Such information is furthermore essential in guiding veterinary antimicrobial stewardship.

In several countries data collection and monitoring systems have been set up to have a better understanding of AMU at the species and herd level, to inform farmers and veterinarians about their own AMU and to allow for benchmarking and identification of high users.

The main purpose of this website is to present an overview of these monitoring systems, assembling key information on species involved, quantification and benchmarking methods and reporting strategies.


AACTING represents a network of professionals involved in the quantification of veterinary Antimicrobial usage at herd level and Analysis, CommunicaTion and benchmarkING to improve responsible use. This network originates from a series of informal meetings between 2014 and 2016 that resulted in the AACTING-project which ran from March 1st, 2017 until February 28, 2018 with financial support of the Joint Programming Initiative on Antimirobial Resistance (JPI-AMR).
