Raccoons also carry another more common problem. It's called Baylisascaris infection. It is caused by a roundworm found in raccoons. It can infect people as well as a variety of other animals, including dogs and cats. Human infections are rare but can be severe if the parasites travel to your eye, organs or the brain. The parasite is endemic in raccoons, with infection rates ranging from 72% to 100%. This parasite lives in their intestinal tract and produces thousands of eggs that are shed in their poop.
Raccoons make communal latrines that can be found at the bases of trees and up in branch crotches, on woodpiles, along and on the top of fences, on roofs, attics, and sandboxes. This results in a lot of the eggs in one specific spot, attracting foraging birds and small rodents to undigested parts. This continues the parasite’s life cycle as it infects and kills the intermediate host. Then the raccoon scavenges the dead, becomes infected with the larva and round and round we go.
The immensity of these worms can cause significant tissue trauma, especially in young children with their small bodies. The most common diagnosis from infection is eosinophilic meningoencephalitis, in which the brain and spinal cord and the meninges membranes surrounding the two become enormously inflamed. Have you heard of meningitis?
But, how to protect ourselves and our pets? How can we get raccoons to move on?
