Common-source outbreak of trichinosis associated with eating raw home-butchered pork.

Four patients had trichinosis after consuming raw home-butchered pork. The patients had fever, myalgias, periorbital edema, and conjunctivitis. All of the patients had nausea, vomiting, or diarrhea (corresponding to the intestinal phase of the infection) seven to ten days before the onset of fever and myalgias. Laboratory findings included eosinophilia, elevated serum CPK and aldolase values, and seroconversion of Trichinella serology one month after onset of myalgias. The patients were treated with mebendazole and prednisone and recovered uneventfully.
