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 on 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. The AACTING project is running from March 1st, 2017 until February 28, 2018 and is funded by the Joint Programming Initiative on Antimirobial Resistance (JPI-AMR).

The 15th International Symposium of Veterinary Epidemiology and Economics is organised this year in Chiang Mai, Thailand, from 12-16 November. ISVEE15 offers several pre- and post-symposium workshops.
Of particular interest is the Pre-symposium Workshop on Monitoring of antimicrobial usage and translating results into action.
Visit the Symposium website for all information.

First AACTING Conference


Ghent Overview

Quantification, Benchmarking and Stewardship of Veterinary Antimicrobial Usage

First International Conference

27 - 28 February @ Ghent, Belgium

With this noon-to-noon conference, the AACTING network aimed at gathering and inspiring people active or interested in the highly relevant topics of quantification, benchmarking and stewardship of (veterinary) antimicrobial usage.

The Conference was a huge success! Check the page for all information.
