Trichinellosis is both of veterinary and medical importance in countries where pig breeding and pork consumption exists. In Iran, people are forbidden to consume pork because of the religious regulations. Therefore, there have not been any human cases over the past decades except a doubtful case based on serological test. Although there are some sylvatic trichinellosis in wild life in different parts of Iran, but a little is known about the current prevalence in wild animals. To date, some cases of Trichinella nelsoni in golden jackals from Khuzestan Province; Trichinella spiralis in wild boars, brown bears, golden jackals, jungle cat, from Mazandaran Province and stray dogs, Jackals, red fox, hyena, Meriones percicus in Isfahan; finally T.spiralis nelsoni in Herpestes auropuntatus from Khuzestan were reported. Based on these data and consumption of animal derived food products among some local hunters, and not a safe and insure rodent control, trichinellosis could be concern as an emerging disease, so more investigation and clinical awareness are needed in this regard.
