The objective of the focus action was to sample and obtain isolates from bacteria of the genus Escherichia coli that produce ESBL (extended-spectrum beta-lactamases), AmpC (AmpC beta-lactamases), or carbapenemase. The bacteria were obtained from beef and pork.

ESBL, AmpC, and carbapenemase are enzymes that act on different antibiotics (e.g., penicillin) and can render them ineffective.

349 samples of beef and 350 samples of pork from all over Austria were tested.

• ESBL/ AmpC-forming E. coli were detectable in seven samples of beef and in 35 samples of pork.
• Carbapenemase-forming E. coli were not detectable in any sample.
