An increased incidence of domestic hepatitis A without any obvious source of infection in Sweden and a small outbreak in late spring 2001 led to the undertaking of a case-control study. Consumption of imported rocket salad was clearly associated with disease (odds ratio 9.1, 95% confidence interval 1.5 to 69). The importation of vegetables from countries where hepatitis A is endemic to countries where this disease is not endemic continues to be a public health problem.
