Exposure to E. coli with important β-lactamases (βL) via irrigation water to lettuce Probabilistic modeling, sensitivity analysis and scenario analysis performed Three percent consumers exposed to 106.4 ± 106.7 (95% CI: 105.1–107) cfu per serving. Exposure affected by percent βL, water quality, gene transfer, washing, disinfection. Reduction in water contamination, storage period, growth rate, percent βL important
