Raccoons are widespread wildlife, commonly found in diverse environments, including urban and suburban settings. Their distinctive masked faces and adaptable nature often spark curiosity, yet they can also raise concerns about potential risks to human safety. This article explores the dangers associated with raccoons and provides insights into how to minimize risks.
Physical Threats from Raccoons
Raccoons are generally not aggressive towards humans and prefer to avoid confrontation. However, they can inflict physical harm through bites and scratches if provoked, cornered, or when protecting their young. Unprovoked attacks are rare.
Physical encounters might arise if a raccoon feels threatened, has become accustomed to human feeding, or is injured. Raccoons may display defensive behaviors like growling, puffing up their fur, or lunging as a bluff to create an opportunity to escape. Their sharp teeth and claws can cause deep wounds, which can lead to infections. If a bite or scratch occurs, it is important to clean the wound thoroughly with soap and water and seek immediate medical attention.
Raccoons and Disease Transmission
Raccoons can carry and transmit several diseases to humans and pets. Rabies is a serious viral disease that affects the central nervous system and is almost always fatal once symptoms appear. Raccoons are one of the most common carriers of rabies in North America, primarily transmitted through saliva via bites or scratches. If exposure to rabies is suspected, immediate medical attention is necessary, as post-exposure prophylaxis can prevent the disease.
Raccoon roundworm, caused by the parasite Baylisascaris procyonis, is another health concern. Raccoons shed millions of microscopic roundworm eggs in their feces. Humans become infected by accidentally ingesting these eggs, which can be found in contaminated soil, water, or objects. While human infections are rare, they can be severe, as the larvae migrate through the body, potentially affecting the eyes, organs, or brain, leading to neurological damage, blindness, or even death. Symptoms typically appear one to four weeks after exposure and can include nausea, tiredness, liver enlargement, and loss of coordination.
Distemper is a common viral disease among raccoons, affecting their respiratory, gastrointestinal, and nervous systems. While highly contagious among raccoons, it can also transmit to unvaccinated dogs and other wildlife through direct contact or bodily fluids. It is not transmissible to humans. Symptoms in infected raccoons can resemble rabies, causing disorientation or erratic behavior, but it does not pose a direct health threat to people.
Minimizing Risk and Coexisting Safely
Humans can minimize risks associated with raccoons and promote safe coexistence through several preventative measures. Securing outdoor food sources is a primary step; this includes using raccoon-proof garbage cans with locking lids and avoiding leaving pet food outdoors, especially overnight. Raccoons are opportunistic foragers drawn to easily accessible food.
Sealing potential entry points into homes is also important to prevent raccoons from seeking shelter indoors. Raccoons can enter attics, chimneys, and crawl spaces through openings like loose shingles or uncovered vents. Regularly inspecting and repairing these areas can deter them from establishing dens.
If a raccoon is encountered, maintaining a safe distance is advisable. Avoiding direct contact and never attempting to handle them, even if they appear calm or friendly, helps prevent bites or scratches. If a raccoon appears sick, injured, or exhibits unusual aggression, contacting local animal control or wildlife authorities is the appropriate action. These professionals are equipped to handle potentially dangerous or diseased animals safely.
