Eurasian beaver (Castor fiber) population following the introduction especially in recent years has increased considerably in territory of Latvia. Functioning beaver settlement creates new trophic resources - felled trees and caves. These trophic resources attract small rodents which increases the number of predators in area. The only beaver predators can be wolf (Canis lupus), lynx (Lynx lynx), red fox (Vulpes vulpes) and dog (Canis lupus familiaris) in Latvia. Muscle samples from 65 Eurasian beavers were collected during hunting seasons in 2009 and 2012 for Trichinella spp. larval detection. The Trichinella spp. prevalence date of wild boars (Sus scrofa), red foxes, raccoon dogs (Nyctereutes procyonoides) and Eurasian lynx were collected from retained samples analyzes at Institute analyzes at Institute of Food Safety, Animal Health and Environment ''BIOR''. Trichinella britovi larvae were detected in one of 65 analyzed beavers. The highest observed Trichinella sp. prevalence was observed in lynx following by red foxes, raccoon dogs and wild boars, 100%, 70%, 40% and 1.4%, respectively. Despite Trichinella spp. is prevalent in Latvia this is the first when T. britovi was found in Eurasian beaver.
