Possums are common nocturnal marsupials found across North America. While generally docile and non-aggressive, they can bite defensively if they feel threatened or cornered. Understanding the potential risks and proper responses to a possum bite is important for personal safety.
Understanding the Risks of a Possum Bite
The primary danger from any animal bite, including a possum’s, is bacterial infection. Bacteria from the animal’s mouth can enter the wound, potentially leading to infections such as cellulitis, abscesses, or more widespread systemic issues if left untreated. Common bacteria found in animal bites that can cause these infections include Pasteurella multocida, Staphylococcus, and Streptococcus species. Prompt and thorough wound care is important to minimize this risk.
A frequent concern following an animal bite is rabies, though possums pose a very low risk for transmitting this virus. Their lower average body temperature, typically ranging from 94-97°F (34-36°C), makes it difficult for the rabies virus to survive and replicate effectively in their system. While any mammal can theoretically contract rabies, it is extremely rare in possums. However, any animal exhibiting unusual behavior should be treated with caution.
Possums can carry other pathogens, but transmission through a bite is generally uncommon. For instance, leptospirosis is typically spread through contact with urine or contaminated environments, not directly via a bite. Tularemia, a bacterial disease, can be transmitted through bites or scratches, though it is rare. Buruli ulcer has also been linked to possums, with some cases reported after bites or scratches from unwell possums.
Possum bites are usually defensive, occurring when the animal feels trapped or cornered. Their bites can still cause puncture wounds, lacerations, and bruising. These injuries can be painful and may require professional medical assessment and treatment.
Immediate Steps After a Bite
Thoroughly wash the wound with soap and warm, running water for at least 5 to 10 minutes. This action helps to flush out saliva and bacteria from the wound. Following washing, apply an antiseptic solution if available, such as iodine or hydrogen peroxide, and then cover the wound with a clean bandage or cloth to protect it and help control any bleeding.
Professional medical attention is recommended in several situations. You should seek medical care for:
Deep puncture wounds.
Wounds that bleed uncontrollably.
Signs of infection developing, such as increasing redness, swelling, pus, or pain around the bite area.
Fever accompanying these symptoms.
If the possum exhibited unusual behavior or seemed aggressive.
If the bitten individual has a compromised immune system.
A healthcare provider can assess the wound, determine the need for antibiotics, and advise on whether a tetanus shot booster is necessary, especially if your last one was more than five years ago.
If there is any concern about the possum’s health, contacting local animal control or health authorities can be helpful. They may provide guidance on reporting the incident, especially if the animal can be safely observed or contained. This step helps track potential wildlife health issues in the community.
Preventing Possum Encounters and Bites
Preventing possum encounters involves minimizing attractants around your home. Avoid approaching, touching, or feeding any wild animals. This helps maintain their natural wariness of humans and reduces the likelihood of defensive bites.
Securing food sources is an effective way to deter possums from your property. Ensure that trash cans have tight-fitting lids that are difficult for animals to open, and bring pet food and water bowls indoors overnight. Cleaning up fallen fruit from trees in your yard also removes an easy food source that can attract these nocturnal marsupials.
Sealing off potential entry points to structures can prevent possums from seeking shelter in unwanted areas. Inspect homes, sheds, garages, and areas under decks for openings and seal them using appropriate materials like wire mesh or caulk. This denies them access to safe havens.
Supervising pets, particularly at night, can prevent confrontations between domestic animals and possums. Pets may provoke a possum, leading to a defensive bite. Educate children about not touching or approaching wild animals.
