[Sacrocystis hjorti lesions in hunted red deer in Switzerland].

In meat samples from 2 hunted red deer (Cervus elaphus) of different origins (region Ilanz, region Filisur) large-scale greenish tissue discolorations with a gelatinous change of fascia were observed and diagnosed as eosinophilic fasciitis. Sarcocystis hjorti, a recently described Sarcocystis species in red deer and moose in Norway, was found as the causing agent. Foxes are regarded as final hosts in the development cycle of this parasite. Factors leading to such cases of eosinophilic fasciitis due to sarcosporidiosis, which is widespread in farm and wild ruminants and is normally inapparent are largely unknown. According to meat inspection directives carcasses with such discolorations have to be declared unfit for human consumption.
