Raccoons are omnivorous and will eat both plants and meat. In nature, they will eat berries, nuts, insects, eggs, fish and shellfish. In residential areas and areas heavily populated by humans they will scavenge in dumpsters and trashcans, and around pet and livestock feed. They prefer to scavenge easier meals when available.
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 an expert 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.
