title: Alaria alata in wild boars (Sus scrofa, Linnaeus, 1758) in the eastern parts of Germany.
abstract: Over the last decade, incidental findings of Alaria alata in stocks of German wild boar during the official Trichinella inspection have been increased. As early as 2006, the German Federal Institute for Risk Assessment pointed out the possible health risk to the consumer posed by this trematode. However, at that time, reliable data concerning the prevalence of the parasite in German wild boars and feral pigs were lacking especially because no appropriate detection method was available. The development of the A. alata mesocercariae technique (Riehn et al., Parasitol Res 107(1):213-220, 2010) now makes it possible to close the remaining gaps in knowledge in this field. Over a 2-year period, 286 retained samples of fresh meat from wild boars originating from different hunting areas in Brandenburg and Saxony-Anhalt, which were tested negative for A. alata during the official Trichinella inspection in the competent veterinary inspection offices, were reexamined with the A. alata mesocercariae migration technique (AMT). In 33 out of 286 retained meat samples (11.5%) with a preliminary negative report, the trematode was demonstrated during the follow-up examination using AMT. This result especially in connection with the highly heterogeneous distribution of the parasite within the hosts' body (Riehn et al., Parasitol Res 107(1):213-220, 2010; Moehl et al., Parasitol Res 105(1):1-15, 2009) shows clearly that a high number of unreported cases of alariosis in wild boars have to be assumed.
