The misuse and wrong control of antibiotics constitutes not only a great health problem, but also an economic one. Antibiotic resistance causes 25,000 deaths per year in Europe or USA and economic costs of 1.5€ billion per year in EU. Additional hospital costs per patient in OECD countries are estimated in 10,000 to 40,000 UDS.

The sanitary authorities are aware of this serious problem and therefore the use of antimicrobials as growth promoter is forbidden in the European Union since 2006. However, this practice is still authorized in countries such as USA and China where the 75% and 50% of commercialized antibiotics respectively, are used for veterinary treatment.
Different institutions are working to bring awareness to the responsible use of veterinary medicines in animals and the control of residues veterinaries on the different points of food chain. The goals are to protect animal health and welfare, and public health; ensuring that veterinary medicines are used responsibly to optimise their effectiveness now and in the future in all species for relevant illnesses.
