Key Takeaways

  • Raccoons are carriers of several diseases including rabies, roundworms, giardiasis, salmonella, leptospirosis, and salmonellosis.
  • Rabies is a serious concern, as raccoons are the most frequently reported animal species with rabies in the U.S. Symptoms include flu-like symptoms, confusion, hydrophobia, and hallucinations in raccoons.
  • Raccoon roundworm eggs can survive in the soil for several years and can cause cerebral nematodiasis and larval migrans in humans.
  • Direct or indirect contact with raccoon waste can lead to transmission of diseases like giardiasis, salmonella, and leptospirosis. Proper waste management and avoiding direct contact are essential preventive measures.


Rabies is transmitted to humans and other animals through the bite or scratch of an infected raccoon. In Pennsylvania and New England, raccoons are known carriers of rabies, making it essential to exercise caution when encountering them. The disease can manifest as flu-like symptoms, confusion, hydrophobia, and hallucinations in raccoons. It's important to note that rabies can remain dormant in an animal for an extended period before showing symptoms, making it challenging to detect. Raccoons are the most frequently reported animal species with rabies in the U.S., particularly in the eastern and southeastern regions. Any contact with raccoon feces, saliva, or an encounter resulting in a bite or scratch should be taken seriously. If exposed to a raccoon or any wildlife suspected of carrying rabies, seeking medical attention is crucial. Additionally, reporting the incident to Public Health authorities is essential to ensure prompt evaluation and appropriate measures. Proper wildlife control and avoiding contact with potentially infected animals are crucial steps in preventing the spread of rabies.


Roundworms, specifically Baylisascaris procyonis, are intestinal parasites found in raccoons that can pose significant health risks to humans and other animals. These roundworms are a concern due to their ability to cause cerebral nematodiasis and larval migrans. The transmission of Baylisascaris commonly occurs through the ingestion of infective eggs from raccoon feces. Raccoon roundworm eggs can survive in the soil for several years and become infectious after 2-4 weeks, posing a risk of transmission to humans.

  • Wildlife: Raccoons are carriers of Baylisascaris procyonis, and their presence in urban and suburban areas increases the risk of contact with roundworm eggs.
  • Disease: In humans and other animals, the infection can lead to severe symptoms such as tiredness, lack of coordination, loss of muscle control, blindness, and coma.
  • Contact: Direct or even indirect contact with raccoon feces can lead to the transmission of roundworm eggs, emphasizing the importance of proactive measures to prevent exposure.

It is crucial to take necessary precautions, such as avoiding contact with raccoons and their feces, to minimize the risk of roundworm infection and its associated health implications. If there is a suspicion of exposure to raccoon feces, seeking immediate medical attention is recommended to prevent potential health risks.


Giardiasis, caused by exposure to raccoon waste, poses health risks due to the transmission of parasites in the feces or urine. This bacterial disease can lead to symptoms such as nausea, stomach cramps, and diarrhea. The presence of wildlife such as raccoons increases the risk of disease transmission, as their waste may contain parasites that cause giardiasis. Additionally, raccoon waste can also harbor other harmful pathogens, such as Salmonella bacteria, which can further escalate health concerns. Therefore, it is crucial to take preventive measures to minimize contact with raccoon waste and reduce the risk of contracting giardiasis and other related diseases. Proper waste management and avoiding direct contact with raccoons and their waste are essential steps in preventing the spread of giardiasis. If exposure to raccoon waste occurs, seeking medical attention and thorough hygiene practices are recommended to address and mitigate the potential health risks associated with giardiasis.


Leptospirosis, caused by Leptospira bacteria found in the urine of infected animals, including raccoons, poses significant health risks due to potential transmission through urine contamination of feed and water. This dangerous disease can lead to severe health complications if not addressed promptly. Here are some key points to consider:

  • Transmission: Leptospirosis can be transmitted to humans and other animals through direct contact with contaminated urine or water sources. This makes it crucial to handle raccoon-infested areas with caution to prevent exposure.
  • Organ Affection: The bacteria can affect the liver and kidneys, potentially leading to organ damage if left untreated. Understanding the symptoms and seeking medical attention is essential for timely intervention.
  • Rabies Cases: In areas with high raccoon populations, the risk of leptospirosis may coincide with the presence of rabies cases. This emphasizes the need for preventive measures and awareness to protect against multiple health threats.


Salmonellosis, caused by ingestion of Salmonella bacteria, presents a significant health risk due to its potential transmission through contaminated food and water sources. This bacterial infection can be particularly dangerous for young children, the elderly, and individuals with weakened immune systems. Common symptoms of salmonellosis include abdominal pain, diarrhea, fever, and muscle aches. In severe cases, it can lead to loss of muscle control and dehydration. Salmonella, which can survive in the human body for up to one week, can also be spread to house pets and humans.

To highlight the importance of preventing salmonellosis, here's a table illustrating key points:

Key Points Details
Symptoms Abdominal pain, diarrhea, fever, muscle aches
High-Risk Individuals Young children, the elderly, individuals with weakened immune systems
Potential Complications Loss of muscle control, dehydration
Prevention Proper hygiene, minimizing exposure to raccoon waste, and avoiding contaminated food and water sources

It's crucial to take preventive measures to minimize exposure to raccoon waste and maintain hygienic practices to reduce the risk of salmonellosis transmission.
