Global Strategy for Containment of Antimicrobial Resistance. Discussion The main limitations of this study were the absence of previous studies on ESBL-producing Enterobacteriaceae in bulk-tank milk from comparable dairy regions of Colombia, which would have estimated frequency according to national productive conditions, and a larger budget, which would allow larger sample size and different time periods.

Epidemiology and successful control of a large outbreak due to Klebsiella pneumoniae producing extended-spectrum beta-lactamases. The low frequency of ESBL-producing Enterobacteriaceae in bulk-tank milk could be a result of the high hygiene standards required by milk processing companies in Antioquia to purchase raw milk.
