Foodborne parasitic infections: Trichinellosis (trichinosis)

Overview

Trichinellosis (trichinosis) is a zoonosis, caused by roundworms of the genus Trichinella. Humans, and domestic and wild animals can be infected and become carriers of the parasites. Domestic pigs, wild boars, bears, rodents and horses are reservoir animals.

Trichinella spp. occur worldwide, most frequently in regions with temperate climates. About 10,000 human infections occur annually worldwide. Cultural factors such as traditional dishes based on raw or undercooked meat or meat-derived products play an important role in the epidemiology of the disease.
