Raccoons are omnivorous and will eat both plants and meat. In the wild, they will eat berries, nuts, insects, eggs, fish and shellfish. In residential areas they will scavenge in dumpsters, trashcans, and pet and livestock food.
When disturbed, raccoons can become aggressive and transfer diseases via their bites and scratches. They can be carriers of rabies which is spread through their bites and scratches. If a raccoon is active during the day, they may be carrying rabies, be sure to contact the authorities to safety handle the situation.
There are also several diseases that raccoons carry that can be transferred through their feces and urine. A few examples of these are the roundworm parasite, a bacterial infection called Leptospirosis, and Salmonella.
