Unfortunately, not a great deal is known about this dangerous and potentially fatal parasite, nor are there any effective treatments at the present time. We do know that the roundworm eggs must be ingested at the right time in order for an infection to occur. Young children, playing in outdoor situations frequented by raccoons, can become victims by inadvertently ingesting roundworm eggs. In addition, we know that infectious eggs can survive for decades in the soil. We also know that many people can be infected and never become symptomatic. It is very important to learn to recognize raccoon toilets so that they can be properly removed and sanitized. To ensure that raccoons do not return, follow up with other appropriate FAQs to learn how to exclude raccoons from your area.
