3.1. Prevalence of Trichinella larvae in wild bears

Trichinella larvae were detected in 7 of the 353 bears examined (2.0%, Table 1). The infection rate of brown bears in Hokkaido was 2.5%; at the subprefecture level, it was 18.2% in Sorachi, 5.3% in Shiribeshi , and 2.3% in Hiyama ( Table 2). Among the 117 Japanese black bears examined, Trichinella larvae were detected in one bear (0.9%, Table 2) which was captured in Iwate Prefecture. All positive bears were adults, with LPG ranging from 0.3 to 180.0 ( Table 3).
