Sir,
β-Lactam antibiotics are extensively used in human and veterinary medicine. The detection rate of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae isolated from humans has increased rapidly worldwide.1 In addition, ESBLs have been increasingly described in bacterial populations circulating in animals.2,3 Recently, a high diversity of ESBLs in Escherichia coli was reported in Belgian poultry farms. In that instance, CTX-M enzymes were the predominant ESBL family.4 CTX-M-2-producing Salmonella enterica serovar Virchow strains and TEM-52-producing S. enterica serovar Infantis strains have also been isolated from Belgian poultry.2,3 This raises a potential public
