A public health advisory sent out Friday says anyone who has eaten uncooked walrus recently, and has experienced stomach pain, muscle pain, diarrhea, swollen eyelids, sweating and weakness, may be infected with trichinella, 'a parasite that causes worm disease.'

A walrus has tested positive for trichinella, also known as “pork worm” in Sanikiluaq, Nunavut according to the territorial health department.

Alaskans from St. Lawrence Island were hospitalized with the food-borne parasite trichinella, which used to more typically infect pork. The CDC and state public health officials issued warnings.
