Dead animals can pose a significant risk to both human health and the environment, especially when they die in or around homes.
Whether it’s wildlife like skunks, opossums, rodents, or raccoons, these animals can often enter homes seeking refuge during extreme weather conditions.
Once they perish, their remains can introduce a host of problems. From foul odours to the spread of diseases, dead animals must be dealt with by professionals to ensure safety.
Let’s get straight to the point
Dead animals can pose significant health and environmental risks, especially when found near homes.
Decomposing carcasses release harmful bacteria, foul odours, and attract vermin like fleas and ticks that can transmit diseases to humans and pets.
Health hazards include respiratory irritation, skin rashes, and potential exposure to serious diseases like rabies, anthrax, and tularemia.
Proper protective gear is essential when handling dead animals, but professional removal and disinfection are recommended to prevent contamination and ensure safety.
Taking precautions can help protect against the serious health risks associated with dead animals.
Potential Hazards of Decomposing Animals
Health Risks from Decomposition
When you find a dead animal on your property, it’s essential to be aware of the potential health hazards associated with its decay.
The decomposition of animals can introduce harmful pathogens into the environment, especially if the carcass is in close proximity to your water supply.
Contamination of groundwater is a serious concern in rural areas or properties that rely on well water.
Odours from Dead Animals
One of the first signs of a dead animal in or around your home is the foul stench that accompanies decomposition.
The smell can be unbearable and linger for weeks if not properly dealt with. This is especially problematic when the carcass is hidden in an attic, crawlspace, or behind walls, where it’s difficult to access.
Bacteria produce around 400 different compounds during decomposition, which include hydrogen sulphide, benzene derivatives, and methanethiol.
These compounds collectively cause the pungent odour. Inhaling these gases can aggravate respiratory conditions and contribute to health problems.
Bacteria in Decomposing Animals
Decomposing carcasses are breeding grounds for harmful bacteria, including salmonella, E. coli, and tularemia.
These bacteria can easily spread if the animal is handled improperly. For this reason, wearing protective gear such as gloves, masks, and safety goggles is essential when dealing with a dead animal.
However, the safest option is always to contact a professional to remove the carcass and disinfect the area to avoid any health risks.
Vermin and Parasites
A dead animal quickly becomes a magnet for vermin, including flies, fleas, and ticks, which can spread diseases to both humans and pets.
Parasites, such as tapeworms, are particularly dangerous because they often move to a new host after their initial one has died.
Pets can become infected by simply coming into contact with or consuming parts of the carcass.
If you or your pet comes into contact with a dead animal, it’s crucial to seek immediate medical or veterinary assistance to prevent any possible spread of disease.
Hygiene and Sanitation Concerns
Worms and Other Pests
Worms and other pests thrive on dead animals, causing severe hygiene issues. These pests are not just unsanitary; they can also leave behind unsightly and damaging stains on furniture, carpets, and attics.
In Australia, where wildlife frequently comes into contact with urban areas, the threat of pests feeding off dead animals can be even more pronounced.
For example, flea infestations are common when dead animals are left untreated. Fleas, in search of a new host, will easily jump to pets or humans, leading to infestations that are difficult to eradicate.
Rashes and Skin Issues
Handling dead animals without protective equipment can result in severe skin rashes.
Many people may underestimate the risk of touching an animal carcass directly, but exposure to the decaying flesh can lead to skin irritation or, in more severe cases, bacterial infections.
Always wear protective clothing when dealing with any dead animal to minimise these risks.
Residues Left by Dead Animals
Even after a dead animal is removed, it can leave behind harmful residues. Cleaning the area with bleach or an enzymatic cleaner is recommended, but it’s essential to wear protective gear to avoid any contact with remaining bacteria or pathogens.
Pulmonary Diseases and Allergic Reactions
Respiratory Irritation
The gases produced during the decomposition process can cause respiratory irritation. For those with existing lung conditions, exposure to these odours can exacerbate symptoms, leading to coughing, shortness of breath, and other respiratory issues.
Allergies and Pathogens
The toxic dust and fumes released by decomposing animals can also trigger allergic reactions.
Additionally, certain animals, like rats, can carry pathogens that can be transmitted to humans, posing even further health risks.
The Risk of Infectious Diseases from Dead Animals
Rabies
While the risk of contracting rabies from a dead animal is low, it’s still a concern. The rabies virus can survive in an animal’s saliva for a short time after death.
If the animal’s saliva comes into contact with an open wound, there is a potential for infection, although the likelihood is small.
Anthrax
A more significant concern in Australia and other regions is anthrax, which can be transmitted from dead animals to humans through bacterial spores.
These spores can survive for decades, and even old animal graves can pose a risk if disturbed.
Anthrax immunisations are available, but anyone who suspects exposure should seek medical help immediately, as the disease can be fatal.
Tularemia
Another bacterial disease spread by dead animals is tularemia. This disease can be contracted by breathing in, touching, or consuming bacteria from the dead animal.
The symptoms include fever, headaches, nausea, and swollen glands. Left untreated, tularemia can be life-threatening.
Parasites in Dead Animals
Ticks, Fleas, and Mites
Dead animals are often infested with ticks, fleas, and mites, which will seek out new hosts once the animal has died.
These parasites are known to carry a wide range of diseases, including Lyme disease, scabies, typhus, and even the bubonic plague. Although rare, these diseases are serious and can have long-term health implications.
Worst-Case Scenarios: Carcasses in Air Conditioners
One of the worst situations is when a wild animal dies in an air conditioning system or ventilation duct.
As the carcass decomposes, the smell is circulated throughout the home, and the situation worsens as time passes.
Larger animals may take over a month to fully decompose, meaning the foul smell can linger, making the environment nearly uninhabitable.
Conclusion
In Australia, wildlife such as skunks, opossums, rats, and raccoons can enter homes during extreme weather conditions, leaving behind their carcasses in hard-to-reach areas.
The decomposition of these animals poses several health risks, including odours, bacteria, and parasites.
Removing the dead animals immediately is critical to prevent the spread of diseases and the worsening of hygiene issues.
In addition to the potential spread of diseases like rabies, anthrax, and tularemia, dead animals can host fleas, ticks, and other pests that can transmit Lyme disease, scabies, and even the bubonic plague.
It is always advisable to contact a professional to handle dead animal removal and properly disinfect the area.
By being aware of the dangers of dead animals and taking proper precautions, you can protect yourself, your family, and your pets from the serious health risks these situations pose.
