What-if analysis related to probability of colonization in feed, restriction on import of animals from countries with weak surveillance for CPE, and less strict biosecurity practice in local farms.

Scenario	CPE Source Affected	Parameter Changed	Baseline Number of Introductions from Affected Source (95% Range)	Changed Number of Introductions from Affected Source (95% Range)
Contamination of E. coli in feed reaches concentration of maximum rejection limit according to GMP+	Feed	$Ecol{i}_{concF}$	767 (244, 1679)	775 (246, 1668)
The Netherlands only allows import of livestock from EU member states that sample ≥100 animals in CPE surveillance	Imported livestock	$P_{CP{E}_A}$	48 (4, 214)	14 (0, 58)
Lower biosecurity: companion animals have full access to livestock areas in broiler, pig, and veal calf farms	Companion animals	$P_{barnC}{}_{}$	0 (0, 0)	2 (1, 7)
Lower biosecurity: non-compliance with hand hygiene	Travelers and hospitalized patients	$Ecol{i}_{hand}$	1 × 10−4 (9 × 10−6, 8 × 10−4)	4 × 10−3 (3 × 10−4, 3 × 10−2)
