Trichinella spiralis larvae were found in 5 of 21,143 wild boars and 1 of 16 brown bears examined in the 5-year period from 1967 to 1971, and in 38 of 63 golden jackals (Canis aureus), 2 of 3 jungle cats (Felis chaus), and none of 3 other carnivores, 30 rodents, and 20 shrews examined in 1972. Infection has not been reported in more than 500,000 domestic pigs examined for Trichinella in the Teheran abattoir, although most of the pigs were raised in the Caspian region. Human infection from eating undercooked infected wild boar or brown bear probably occurs; one suspected case has been reported.
