Outbreak of Trichinella T9 Infections Associated with Consumption of Bear Meat, Japan

Emerg Infect Dis. 2018 Aug;24(8):1532-1535. doi: 10.3201/eid2408.172117.

Abstract

An outbreak of trichinellosis occurred in Japan in December 2016. All case-patients had eaten undercooked bear meat, from which Trichinella larvae were subsequently isolated. DNA sequencing analysis of the mitochondrial genes cytochrome c-oxidase subunit 1 and internal transcribed spacer 2 confirmed that Trichinella T9 had caused the outbreak.

Keywords: Japan; Trichinella T9; bear meat; foodborne disease; outbreak; parasites; trichinellosis.
