"Raccoons are also important vectors for the spread of infection diseases. They’re known to carry rabies, and a 2011 report in the Journal of Parasitology even found evidence for the potentially dangerous and brain-altering parasite Toxoplasmosa gondii in raccoon droppings."

It would be fairly surprising if raccoons didn't carry toxoplasma: pretty much every US cat does, about 60 million Americans, and 5-7% of Japanese cattle and swine. It's rare that it causes problems for anyone except newly infected pregnant women.
