SCIENTIFIC REPORT APPROVED: 28 June 2017 doi: 10.2903/j.efsa.2017.4872 ECDC/EFSA/EMA second joint report on the integrated analysis of the consumption of antimicrobial agents and occurrence of antimicrobial resistance in bacteria from humans and food-producing animals Joint Interagency Antimicrobial Consumption and Resistance Analysis (JIACRA) Report European Centre for Disease Prevention and Control (ECDC), European Food Safety Authority (EFSA) and European Medicines Agency (EMA) Abstract The second ECDC/EFSA/EMA joint report on the integrated analysis of antimicrobial consumption (AMC) and antimicrobial resistance (AMR) in bacteria from humans and food-producing animals addressed data obtained by the Agencies’ EU-wide surveillance networks for 2013–2015. AMC in both sectors, expressed in mg/kg of estimated biomass, were compared at country and European level. Substantial variations between countries were observed in both sectors. Estimated data on AMC for pigs and poultry were used for the first time. Univariate and multivariate analyses were applied to study associations between AMC and AMR. In 2014, the average AMC was higher in animals (152 mg/kg) than in humans (124 mg/kg), but the opposite applied to the median AMC (67 and 118 mg/kg, respectively). In 18 of 28 countries, AMC was lower in animals than in humans. Univariate analysis showed statistically-significant (p < 0.05) associations between AMC and AMR for fluoroquinolones and Escherichia coli in both sectors, for 3rd- and 4th-generation cephalosporins and E. coli in humans, and tetracyclines and polymyxins and E. coli in animals. In humans, there was a statistically-significant association between AMC and AMR for carbapenems and polymyxins in Klebsiella pneumoniae. Consumption of macrolides in animals was significantly associated with macrolide resistance in Campylobacter coli in animals and humans. Multivariate analyses provided a unique approach to assess the contributions of AMC in humans and animals and AMR in bacteria from animals to AMR in bacteria from humans. Multivariate analyses demonstrated that 3rd- and 4th-generation cephalosporin and fluoroquinolone resistance in E. coli from humans was associated with corresponding AMC in humans, whereas resistance to fluoroquinolones in Salmonella spp. and Campylobacter spp. from humans was related to consumption of fluoroquinolones in animals. These results suggest that from a ‘One-health’ perspective, there is potential in both sectors to further develop prudent use of antimicrobials and thereby reduce AMR. © 2017 European Centre for Disease Prevention and Control, © European Food Safety Authority and © European Medicines Agency.

This is the second report of its kind prepared by the three agencies following a request from the European Commission (EC). The data included in the analyses and the results presented in the report pertain to 2013, 2014 and 2015 and were obtained through five different surveillance/monitoring networks managed by the agencies to collect annual data on AMC and AMR in humans and in food-producing animals in the EU/EEA Member States (MSs) and in Switzerland. The data used in the analyses were collected as part of clinical and epidemiological surveillance/monitoring in both humans and food- producing animals, and were not collected specifically for the purpose of this report. The integrated analyses of data from humans and animals presented here were based on the ‘One-Health’ approach and focused on particular combinations of antimicrobials and bacterial species considered of importance for public health. Compared to the first JIACRA report, the number of countries reporting AMC data increased in both humans (30, previously 28) and food-producing animals (29, previously 26). AMC data from humans are commonly reported as defined daily doses (DDD) per 1,000 inhabitants and per day, whereas the corresponding data in food-producing animals are typically expressed in milligrams of active substance per kilogram of estimated biomass and per year. As a fully comparable measurement unit is not available, AMC data in humans were converted into mass of active substance per kilogram of estimated biomass to make the comparison as consistent as possible. To facilitate the comparison of AMC and AMR and for the sake of consistency with the first JIACRA report, a summary indicator of microbiological resistance (SIMR) was calculated for food-producing animals on the basis of the weighted mean by estimated biomass of the proportions of drug-resistant bacteria in each animal species included in the indicator. For data referring to 2013, the SIMR in bacteria from food-producing animals addressed AMR data covering cattle, pigs and broilers, whereas, for data referring to 2014–2015, AMR data on broilers, fattening turkeys, fattening pigs and cattle under 1 year of age were included. An additional SIMR in bacteria from poultry was also constructed based on AMR data on broilers and turkeys for 2014–2015. These differences reflect changes in the EU legislation on AMR monitoring in food-producing animals implemented in 2014. SIMR were compared to corresponding AMC in food-producing animals. To date, AMC data in food-producing animals are not available by species in the European Surveillance of Veterinary Antimicrobial Consumption (ESVAC) reports, whereas, in this report, an attempt to infer AMC at the animal species level was made. Technically derived estimates of sales of antimicrobials in pigs and poultry were used
