Tapeworm infection resulting from pork eaten at a wedding banquet.

Forty-five people who had attended a wedding banquet were examined by means of both Avidin-Biotin Peroxidase Complex-ELISA (ABC-ELISA) and Kato stool thick smear technic. The results revealed that the positive rates with ABC-ELISA were 15.56% (7/45) and Kato Katz 0.62% (1/161). There was a significant difference between the two positive rates (p < 0.005). Six people at the wedding had taeniasis and 4 of them also had cysticercosis. Local people have no habit of eating uncooked pork, but at this banquet the meat from an infected cysticerci pig was used for preparing dishes for the wedding feast and the cold dishes were contaminated by the bladder worms as the result of using the same chopping block.
