The risk-benefit balance of resistance to ionophores in Enterococcus faecium and Enterococcus faecalis for ionophore coccidiostats in broiler chickens

This article will seek to review the most significant publications in this regard and will also examine national antimicrobial resistance surveillance programmes in Norway, Sweden, Denmark and the Netherlands, in order to further evaluate this concern. The conclusion of the review is that the risk that enterococci may pass from broilers to humans and that antimicrobial resistance gene transfer may occur is negligible, remains unquantified and is highly unlikely to be of significance to human health. Indeed, to date no human nosocomial infections have been linked to poultry sources. Concurrently a review of the possible impact of a policy that limits access for poultry farmers and poultry veterinarians to ionophore coccidiostats in broilers indicates predictable negative consequences with regard to antibiotic resistance of significance to animal welfare and to human health.
