Food is an established source of extended-spectrum (β-lactamase (ESBL)-producing Enterobacteriaceae. Hand hygiene and cooking prevent transmission, but hands could be recontaminated by touching used cutting boards. ESBL-producing Escherichia coli were identified on 12% of cutting boards and 50% of gloves after poultry preparation, pointing to an important source for transmission.
