An outbreak of campylobacter food poisoning in a group of health care
workers is reported. The outbreak involved 12 of 31 staff members atte
nding a departmental party. Investigations revealed that a chicken dis
h was the most likely vehicle of infection. The relative risk of devel
oping symptoms after eating this dish was 6.15 (P<0.002). Further inve
stigation established that not only had the cooking instructions been
misunderstood but storage of the the food the morning of the party did
not comply with Department of Health guidelines. The outbreak was ass
ociated with considerable morbidity and cost. It is important that hea
lth care workers other than professional catering staff are aware of t
he guidelines available to ensure the correct preparation and storage
of food if such events are to be held in hospital departments. It is a
lso important that manufacturers of chicken products ensure that label
ling regarding further cooking is clear and in large print.
