A: Raccoons can be successfully treated with several anthelmintics to kill the adult worms. Effective drugs are piperazine, fenbendazole, pyrantel pamoate, levamisole and organophosphates such as dichlorvos.
There are currently no drugs that can effectively kill the migrating larvae in the body. Laser surgery has been successfully performed to kill larvae present in the retina of the eye, but the damage caused by the migrating larvae is irreversible. Treatment with steroids in intermediate hosts is mainly supportive and is designed to decrease the inflammatory reaction.
Controlling infections of this parasite requires minimizing contact with areas inhabited by raccoons. Fecal contamination of an area can result in millions of eggs being deposited and therefore available for infection. These eggs are extremely resistant to environmental conditions, being able to survive for several years. Any area contaminated with raccoon feces should be cleaned and the feces, as well as any contaminated feed, straw, or hay, burned. Children and pets should be kept away from these contaminated areas until a thorough cleaning has occurred.
