EFSA: foodborne bacteria show high antimicrobial resistance in 2019–2020

30 March, 2022

Data on antimicrobial resistance in zoonotic and indicator bacteria referring to 2019–2020, submitted by 27 EU Member States (MSs), were jointly analysed by the EFSA and the ECDC. Resistance in zoonotic Salmonella and Campylobacter from humans, animals and food, as well as resistance in indicator Escherichia coli and methicillin-resistant Staphylococcus aureus (MRSA) from animals and food were addressed.
In Salmonella spp. from human cases in 2019–2020, resistance to ampicillin, sulfonamides and tetracyclines was observed at overall high levels, while resistance to third-generation cephalosporins in 2020 was noted at overall very low levels of 0.8% for both cefotaxime and ceftazidime, respectively. Resistance to fluoroquinolones was high to very high among Salmonella spp. and indicator E. coli isolates recovered from broilers, fattening turkeys and poultry carcases/meat in 2020. In Salmonella spp. isolates from human cases, a moderate occurrence of resistance to ciprofloxacin was observed in 2019–2020, but among S. Kentucky isolates extremely high prevalence of resistance was noted (82.0% in 2020), and in S. Enteritidis increasing trends in resistance were observed in nine countries over the period 2016–2020, both serovars predominantly being associated with poultry.
Resistance to colistin was uncommon among Salmonella spp. and E. coli isolates recovered from food-producing animals (fattening pigs, calves, Gallus gallus and fattening turkeys) and carcases/meat derived from these animals, although moderate resistance was notably observed in certain Salmonella serovars.
Rates of resistance to ciprofloxacin were very high in C. jejuni and C. coli isolates from humans and very high to extremely high in C. jejuni and C. coli isolates from poultry, pigs and calves.
An improved situation was most pronounced in poultry. Both key outcome indicators show that encouraging progress has been registered in reducing AMR in food-producing animals in several EU MSs over the last years.
