  1. A milk-borne Campylobacter outbreak following an educational farm visit.

    Article - En anglais

    After a nursery school trip to a dairy farm, 20 (53%) of 38 children and 3 (23%) of 13 adult helpers developed gastrointestinal infection.

    Campylobacter jejuni was isolated from 15 primary cases and from 3 of 9 secondary household cases.

    A cohort study of the school party found illness to be associated with drinking raw milk (relative risk 5.4,95% confidence interval 1.4-20.4, P=0.001).

    There was a significant dose response relationship between amount of raw milk consumed and risk of illness (khi2-test for linear trend 12.1, P=0.0005) but not with incubation period, severity of symptoms or duration of illness.

    All 18 human campylobacter isolates were C. jejuni resistotype 02 and either biotype I (number 16) or biotype II (number 2).

    Campylobacter was also isolated from samples of dairy cattle and bird faeces obtained at the farm but these were of different resisto/biotypes.

    Educational farm visits have become increasingly popular in recent years and this outbreak illustrates the hazard of exposure to raw milk in this setting.
