Over the past decade, frequent detection of trematode Alaria sp. mesocercariae in wild boar muscle samples during official Trichinella inspection has raised concern as a potential risk of human and animal health. In the present study 60 wild boar muscle samples were examined with two methods, Alaria sp. mesocercariae migration technique (AMT) and the official Trichinella inspection method (TIM). The results of the present study shows that AMT had 4.86 (95% CI: 2.22-10.99) times higher odds of testing positive than with TIM. The cause of low proportion of positive mesocercariae observation using TIM is mainly associated with inappropriate mesh size of the sieve used in comparison to Alaria alata mesocercariae size. In addition, a shortening the AMT procedure time for 30 min is sufficient to obtain only qualitative results for A. alata mesocercariae in muscle samples.

Key words: Alaria alata, mesocercariae, mesocercariae migration technique, wild boar.
