Having a raccoon bite or scratch, or direct contact of any sort is obviously a concern, but
the bigger concern is contact with raccoon feces or urine, which people can often have inadvertently.
The most serious infection is raccoon roundworm – known as Baylisascaris procyonis. This is a parasite that lives inside raccoon intestines, has little or no harmful effect on raccoons, and sheds eggs into raccoon feces. Once these eggs turn into larvae, they’re extremely resistant to physical or chemical cleaning, and can remain in the environment for long periods of time.
If these larvae are then accidentally consumed by a pet dog or cat, or even a human, they travel through the body and often end up in the brain, causing multiple organ damage, severe neurological impairment, and even death.
There is no effective cure for this condition. We have seen about 30 cases reported worldwide, almost exclusively in kids, including a case in Toronto in 2005. A 2014 study by Claire M. Jardine and colleagues in the Journal of Wildlife Diseases detected these roundworms in 38 per cent of raccoons in Ontario.
