Raccoons defecate in communal sites, called latrines. Often these latrines are located on a raised, flat surface or at the base of a tree. Over time, the scat accumulates. Should you come upon a latrine, it’s best not to investigate too closely, as raccoon feces harbor roundworm (Baylisascaris procyonis) eggs which can be easily ingested and cause harm (serious eye disease, spinal cord or brain damage, or death) to humans. One of these roundworms can produce more than 100,000 eggs a day, and the eggs remain viable for years in the soil.
