Overview
Trichinosis, also called trichinellosis, or trichiniasis, is a parasitic disease caused by eating raw or undercooked pork and wild game products infected with the larvae of a species of roundworm Trichinella spiralis, commonly called the trichina worm. The few cases in the United States are mostly the result of eating undercooked game or home reared pigs. It is most common in the developing world and where pigs are commonly fed raw garbage.
Historical Perspective
Trichinella spiralis was first discovered by James Paget, a English first-year medical student, in 1835.[1] In 1846, Joseph Leidy, an American paleontologist, was the first to discover the association between undercooked meat and development of trichinosis. [2] There have been several outbreaks of trichinosis, most of them for consuming infected pork, wild boar and bear. Although now uncommon as a result of public health control measures. [3][4]

Trichinellosis (trichinosis) is caused by nematodes (roundworms) of the genus Trichinella. In addition to the classical agent T. spiralis (found worldwide in many carnivorous and omnivorous animals), several other species of Trichinella are now recognized, including T. pseudospiralis (mammals and birds worldwide), T. nativa (Arctic bears), T. nelsoni (African predators and scavengers), and T. britovi (carnivores of Europe and western Asia).
