An outbreak of 24 cases of hepatitis A in Aberdeen was traced to a large hotel in the city by epidemiological investigation. Food-specific questioning of those affected, their fellow diners and hotel staff, coupled with serological studies, implicated raspberry mousse prepared from frozen raspberries as the source of the infection. The raspberries were probably contaminated at the time of picking.
