Causative agent	No. of expertsa	Transmission pathway, % (95% UI)						Bayesian adjustment factor (95% UI)
		Food	Environment	Animal–human	Human–human		Travel
Campylobacter spp.	15	82.0 (78.5–85.5)	8.3 (6.7–10.1)	3.1 (2.1–4.3)	0.2 (0.0–0.5)	6.4 (5.0–8.0)		0.17 (0.08–0.32)
Salmonella sp.	14	79.3 (74.7–84.0)	2.7 (1.7–3.8)	10.1 (8.4–12.0)	3.4 (2.4–4.7)	4.5 (3.2–5.9)		0.26 (0.12–0.47)
EHEC	20	77.6 (73.4–81.8)	4.0 (2.8–5.3)	8.5 (6.9–10.4)	6.0 (4.6–7.6)	3.9 (2.8–5.29		2.23 (0.97–4.00)

EHEC: enterohaemorrhagic Escherichia coli; UI: uncertainty interval.
