AB Trichinella  species  are  nematodes  infecting  the  striated  muscle  of  warm-blooded  animals,  and  infection  occurs  by  consumption  of  raw  or  insufficiently  cooked  infected  meat.  Most  human  infections  are  associated  with  undercooked  pork,  although  horsemeat  and  wild  carnivorous  game,  such  as  bear  and  walrus  meat,  may  also  be  sources  of  infection.1  The  disease  occurs  worldwide  in  both  high-  and  low-income  regions,  with  outbreaks  reported  in  the  United  States,  Mexico,  Southeast  Asia,  and  Europe.  Because  of  the  mode  of  transmission,  disease  is  relatively  uncommon  in  predominantly  Moslem  and  Hindu  countries  where  pork  is  rarely  eaten.  Most  cases  are  linked  to  common  source  outbreaks  from  contaminated  meat.  Pork  or  pork  products  account  for  75%  to  80%  of  infections.  In  the  United  States,  trichinosis  is  most  commonly  diagnosed  in  far  northern  Native  Americans,  such  as  the  Inuits,  who  acquire  infection  with  Trichinella  nativa  from  walrus  meat  or  meat  from  other  sea  mammals.  In  this  group,  intestinal  symptoms  are  the  predominant  clinical  manifestations.
