The raccoon (Procyon lotor) is a species native to North America, but which is now spreading throughout Europe. Raccoons have been found to host various Trichinella species. The aim of the present study was to evaluate the effectiveness of using immunological testing of meat juice for determining the occurrence of Trichinella in raccoons. The studies were carried out on 139 animals from three European countries: the Czech Republic, Germany and Poland. Seven meat juice samples were found to be positive for antibodies to Trichinella by ELISA, and another seven were unclear. The ELISA results were confirmed by immunoblot: anti-Trichinella antibodies were identified in 9.35 % of the examined animals. Slight agreement (κ = 0.13) was found between the digestion method and the combined ELISA and immunoblot approach. From the results of our study, we concluded that meat juice may be used as a simple and convenient sample for detection of anti-Trichinella in racoons.
