Abstract

Trichinella spp. are foodborne parasites that can cause severe and potentially fatal disease in humans. Infections occur through consumption of meat containing the infectious stage (L1). In Germany the domestic cycle has been eradicated. In wild animals sporadic occurrence is observed in species such as wild boar, red foxes and raccoon dogs. The omnivore raccoon which is an invasive species in Europe is known as a potential host but has not been studied intensely regarding this parasite in Germany until now, thus resulting in a lack of knowledge about its role in the sylvatic cycle. Raccoons from the urban area of Leipzig were investigated for several pathogens including Trichinella spp. in a cooperative project. Muscle samples of 88 individuals were examined using the artificial digestion method (ADM). One animal was found positive, which is the first detection of this parasite in a raccoon in Germany.
