title: Enteric parasites in workers occupationally exposed to sewage.
abstract: To determine if parasitic infections occur more frequently among workers exposed to wastewater than among controls, parasitologic examinations were performed on stool specimens collected over a 12-month period from sewer and highway maintenance workers. Three of 56 sewer maintenance workers (5.4%) had at least one positive specimen compared with 10 of 69 highway workers (14.5%). The highest rate was found among highway workers engaged in street cleaning. Contrary to studies conducted outside the United States, the present study does not indicate that parasitic infections occur more frequently among sewer workers than among controls in the urban midwestern United States. The results of this study indicate that there may be a risk of parasitic infections among street cleaners.
