Reduction of Baylisascaris procyonis eggs in raccoon latrines, suburban Chicago, Illinois, USA.

ABSTRACT

Baylisascaris procyonis, a common roundworm of raccoons, causes severe or fatal human infections, often in suburban areas. To evaluate the effectiveness of a baiting strategy requiring minimal labor, we distributed medicated baits near raccoon latrines in suburban Chicago, Illinois, USA. This strategy lowered B. procyonis prevalence in raccoons, possibly reducing risk to humans.
