ALARIA SPP. EPIZOOTIOLOGICAL SITUATION IN WILD BOAR IN LATVIA

During the controls for Trichinella in wild boar meat, Alaria spp. mesocercariae in the examined samples are diagnosed. There does not exist a routine veterinary inspection for diagnosis of alariosis (Alaria spp.) in Latvia. The aim of the study was to determine Alaria spp. mesocercariae distribution in wild boar (Sus scrofa) meat in Latvia. Laboratory examination was performed in Latvia University of Agriculture Faculty of Veterinary Medicine laboratory of Parasitology, from 2010 to 2013. Meat samples were examined using artificial digestion method, which in regulation No 2075/2005 is considered an official detection method for Trichinella. In total, 1233 wild boar meat samples from different hunting regions of Latvia were examined. The territory of Latvia was divided into four regions - Kurzeme, Zemgale, Vidzeme and Latgale. For examination we used meat samples from wild boar pillars of diaphragm. Samples were taken from wild boars of different age and gender. The prevalence of infection in the examined wild boar meat samples from all regions was 8.2%, but the intensity of infection 2.8.
