German. The epidemiology of trichinellosis in Germany was investigated by analyzing national surveillance data from 1996-2006. During this period, 95 laboratory-confirmed infections and 12 outbreaks were reported. The highest mean annual incidence was found in immigrants from southeast European countries (0.3 cases/100,000 vs. 0.01 cases/100,000 in the German population) with an incidence rate ratio of 26.0 (95% confidence interval 11.6-51.8). The predominant clinical symptom was muscle pain in 79 patients (83%). Mean diagnostic delay was 49 days. Among patients with reported source of infection (85%; n = 81), the consumption of pork (mostly originating from endemic countries) represented the most frequent exposure (93%; n = 75). In addition, trichinellosis cases were associated with both indigenous (n = 1) and imported (n = 5) wild boar meat. Although domestic pigs in Germany are practically free from Trichinella spp., the parasite was found in German wild animals such as wild boars, foxes, and racoon dogs. We conclude that trichinellosis still remains a public health issue in Germany, especially among individuals with a migrational background. Immigrants from endemic countries need to be educated about the risks of consuming raw or inadequately cooked pork and wild boar products from their homeland. In addition, German healthcare providers need to be aware of trichinellosis, especially in areas with a large immigrant population. © 2008 Mary Ann Liebert, Inc.
