OIE global report shows decreasing trend in antimicrobials used in livestock animals

The OIE World Organization for Animal Health annual report on the use of antimicrobial agents in animals describes the trend of this phenomenon at global and regional level based on data from 2010 to 2015.  

The OIE model used to collect the data was designed to allow all Member Countries to participate in the annual data collection, although quantitative data on antimicrobial agents used in animals are not available for each year.  

Tetracyclines (48%) and macrolides (15%) are the most commonly reported antimicrobial agents used among Member Countries that have provided quantitative data on the use of antimicrobial agents in animals.  

When broken down by OIE Region, Europe provided more quantitative data than other OIE Regions and systematically chose a more advanced Reporting Option. Most European countries in the European Union already have a system in place for data collection on the use of antimicrobial agents in animals, under the European Surveillance of Veterinary Antimicrobial Consumption (ESVAC) project that was launched by the European Medicines Agency in September 2009.  

In other OIE regions such as Africa and Asia, data communication is not sufficient, also due to the fact that they don’t have advanced tools, thus requiring substantial support from the most technologically advanced Member States.  

The model developed by the OIE is not to be considered completed but rather in continuous evolution aimed at obtaining increasingly significant and detailed data. For example, the average weights and sub-categories of animals could be analyzed to reach a certain significance of the data as well as the total number of terrestrial animals produced in a year which would allow contextualising the total amount of antimicrobial agents used in a year.
