The wild boar (Sus scrofa) has a wide geographical distribution and can be an important source of Trichinella spp. infection in humans in Romania. The objective of this study was to identify the presence of Trichinella spp. in the wild boar population in Bihor County, Romania. Eighty four plasma and diaphragm samples, collected from wild boars, were included in this study. Artificial digestion, ELISA and Western blot were performed on these specimens. All diaphragm samples were negative for Trichinella larvae in artificial digestion, while in ELISA, 54 (64.2 %) plasma samples were positive and 6 (7.1 %) plasma samples were doubtful. Western blot was performed on 26 plasma samples from which only 6 (23.0 %) gave a positive result. Serological evidences indicate the presence of Trichinella spp. in wild boars from western Romania. Therefore, human consumers might be at risk to ingest Trichinella larvae, even in low numbers.
