Widespread dissemination of extended-spectrum β-lactamase-producing, multidrug-resistant Escherichia coli in livestock and fishery products in Vietnam

Background Widespread dissemination of extended-spectrum β-lactamase (ESBL)-producing bacteria is a threat to public health. Since livestock products are possible reservoirs of ESBL-producing bacteria, food-borne dissemination of ESBL-producing bacteria and the characteristics of such organisms in food products should be assessed to evaluate potential sources of contamination.
