title: Cohort study of a campylobacteriosis outbreak associated with chicken liver parfait, United Kingdom, June 2010.
abstract: In an outbreak of 24 cases of gastroenteritis among guests at a wedding reception, 13 cases had confirmed Campylobacter infection. In a cohort study, univariate analysis revealed a strong association with consumption of chicken liver parfait: risk ratio (RR): 30.08, 95% confidence interval (CI): 4.34-208.44, p<0.001, which remained after adjustment for potential confounders in a multivariable model: RR=27.8, 95% CI=3.9-199.7, p=0.001. These analyses strongly support the hypothesis that this outbreak was caused by the consumption of chicken liver parfait.
