Long-lasting <i>Campylobacter jejuni</i> contamination of milk associated with gastrointestinal illness in a farming family

Abstract

This report describes an outbreak of gastroenteritis of 5 months' duration in a farming family, associated with the consumption of unpasteurized cows' milk, where Campylobacter jejuni was implicated. A total of six individuals in the family acquired the illness, and two had several episodes of diarrhoea within the 5-month period. Identical PFGE genotypes of C. jejuni were isolated from human and bovine faeces, and bulk tank milk samples. Incompletely sealed rubber liners fitted to a milking machine shortly before the outbreak started was the probable reason, allowing faecal material to contaminate the milk over the period concerned.
