Food poisoning among clients of a meals on wheels service

Sixty-one out of 105 elderly people who received a meal from a meals on wheels service developed a diarrhoeal illness. Twenty-seven of the 61 were admitted to hospital and three died. Epidemiological evidence suggested that food poisoning was associated with eating strawberry mousse made with raw eggs. Salmonella enteritidis phage type 4 was identified as the causative organism.
