Domestic pigs in Switzerland have been considered Trichinella-free for decades, despite the occurrence of Trichinella in the wildlife cycle. In order to reevaluate the present epidemiological situation, tissue samples from 11226 domestic pigs, 356 wild boars and 452 foxes were examined using the standard artificial digestion method. A simultaneous serological study, extended to include 25239 sera from sows provided by a Swiss pig serum bank, was also undertaken. The results of both studies support the conclusion that Trichinella spp. do not occur within the domestic pig population in Switzerland. Among the fox population, Trichinella was detected in four (0.9%) of the animals tested using the digestion method, and Trichinella britovi was identified as the infecting species by RAPD fingerprint analyses.
