Sj. O'Brien et al., Contact with farming environment as a major risk factor for shiga toxin (Vero cytotoxin)-producing Escherichia coli O157 infection in humans, EM INFECT D, 7(6), 2001, pp. 1049-1051
In a prospective, unmatched case-control study of sporadic Shiga toxin (Ver
o cytotoxin)-producing Escherichia coli O157 (STEC O157) infection in Engla
nd, exposure to the farming environment emerged strongly as a risk factor (
adjusted odds ratio = 2.45; 95% confidence intervals = 1.49-4.02; p=0.0004)
posing further challenges and opportunities for prevention.
