Proportion of stored foods and flies positive for Escherichia coli and diarrheagenic E. coli in rural households with children < 24 months old in rural Bangladesh

	Food, N = 182 n (%)	Paired samples, N = 68
		Food n (%)	Fly n (%)
E. coli ≥ 1 MPN/dry g food	111 (61)	44 (65)	–
E. coli ≥ 100 MPN/dry g food or fly	30 (16)	14 (21)	41 (60)
E. coli log MPN, mean (95% CI)	0.3 (0.1–0.5)	0.5 (0.1–0.8)	2.9 (2.6–3.2)
Diarrheagenic E. coli gene	15 (8)	5 (7)	1 (1)
Enteropathogenic E. coli	7 (4)	2 (3)	1 (1)
Enteroaggregative E. coli	10 (5)	3 (4)	–

CI = confidence interval; MPN = most probable number.
