Tongue has higher larval burden of Trichinella spp. than diaphragm in wolverines (Gulo gulo).

•Tongues are a better predilection site (more larval burden) than diaphragms for Trichinella spp. larvae in naturally infected wolverine.•The predilection site of Trichinella spp. larvae did not vary significantly between juvenile and adult wolverines, between male and female wolverines and among wolverines classified as having low and high larval intensities overall.•Trichinella T6 was the predominant genotype, followed by T. nativa (T2) and larval burden of Trichinella T6 was higher in tongues than diaphragms.
