Diseases from Raccoon Feces: Symptoms, Impacts, and Prevention

Overview of Baylisascaris procyonis and Other Pathogens

Raccoons, while fascinating creatures, can pose significant health risks to humans and pets through their feces. One of the primary concerns is the presence of Baylisascaris procyonis, a parasitic roundworm found in raccoon intestines. This parasite, along with other pathogens, can cause serious diseases if humans or pets come into contact with contaminated feces.

Baylisascaris procyonis

Baylisascaris procyonis is a type of roundworm that commonly infects raccoons. The adult worms live in the raccoon’s intestines, where they produce eggs that are excreted in the feces. These eggs can survive in the environment for years and are highly resistant to adverse conditions. When humans or animals ingest these eggs, they hatch into larvae that can migrate through the body, causing severe damage to tissues and organs.

Life Cycle and Transmission

  1. Egg Stage: The eggs of Baylisascaris procyonis are excreted in raccoon feces.
  2. Infective Stage: These eggs become infective after 2-4 weeks in the environment.
  3. Accidental Hosts: Humans and other animals can accidentally ingest these infective eggs through contaminated soil, water, food, or by handling contaminated objects.

Other Pathogens in Raccoon Feces

Apart from Baylisascaris procyonis, raccoon feces can harbor various other pathogens that pose health risks:

  1. Leptospira spp.: Bacteria causing leptospirosis, a disease that affects humans and animals. Symptoms include fever, headaches, muscle aches, and in severe cases, liver or kidney damage.
  2. Salmonella spp.: Bacteria causing salmonellosis, characterized by diarrhea, fever, and abdominal cramps.
  3. Giardia spp.: Protozoa causing giardiasis, leading to diarrhea, abdominal pain, and nausea.
  4. Cryptosporidium spp.: Protozoa causing cryptosporidiosis, resulting in gastrointestinal illness with diarrhea and stomach cramps.

Symptoms and Health Impacts of Raccoon Feces Exposure

Exposure to raccoon feces can lead to various health issues, depending on the pathogens involved. Below are the primary symptoms and health impacts associated with exposure to Baylisascaris procyonis and other common pathogens.

Baylisascaris procyonis

Baylisascaris procyonis infection in humans can lead to a condition known as Baylisascariasis. The symptoms and severity depend on the number of eggs ingested and the migration path of the larvae.


  1. Neurological Symptoms: If larvae migrate to the brain, they can cause severe neurological symptoms such as loss of coordination, weakness, altered mental status, and seizures.
  2. Ocular Symptoms: If larvae migrate to the eyes, they can cause visual disturbances or even blindness.
  3. Visceral Symptoms: Migration to other organs can cause damage and inflammation, leading to organ dysfunction.

Health Impacts

  • Neurological Damage: Permanent neurological impairment or death in severe cases.
  • Ocular Damage: Permanent visual impairment or blindness.
  • Organ Damage: Chronic health issues depending on the affected organs.


Leptospirosis is a bacterial infection that affects both humans and animals. It is transmitted through contact with water or soil contaminated with the urine of infected animals.


  1. Flu-like Symptoms: Fever, chills, headache, muscle aches.
  2. Severe Symptoms: Jaundice, abdominal pain, vomiting, diarrhea, rash.

Health Impacts

  • Liver Damage: Hepatitis and jaundice.
  • Kidney Damage: Acute kidney failure.
  • Respiratory Distress: Severe respiratory issues in advanced cases.
  • Meningitis: Inflammation of the membranes around the brain and spinal cord.


Salmonellosis is caused by Salmonella bacteria, which can be present in raccoon feces. It is typically transmitted through ingestion of contaminated food or water.


  1. Gastrointestinal Symptoms: Diarrhea, fever, abdominal cramps.
  2. Systemic Symptoms: In severe cases, the infection can spread to the bloodstream and other body parts.

Health Impacts

  • Dehydration: Severe diarrhea can lead to dehydration.
  • Bacteremia: Spread of bacteria to the bloodstream, leading to severe illness.


Giardiasis is an infection caused by the protozoan parasite Giardia. It is transmitted through the ingestion of contaminated water, food, or contact with infected feces.


  1. Gastrointestinal Symptoms: Diarrhea, abdominal cramps, bloating, nausea.
  2. Malabsorption: Chronic infection can lead to malabsorption of nutrients.

Health Impacts

  • Weight Loss: Due to malabsorption and chronic diarrhea.
  • Dehydration: From prolonged gastrointestinal symptoms.


Cryptosporidiosis is caused by the protozoan Cryptosporidium. It is primarily transmitted through contaminated water.


  1. Gastrointestinal Symptoms: Watery diarrhea, stomach cramps, nausea, vomiting.
  2. Dehydration: Severe diarrhea can lead to dehydration.

Health Impacts

  • Chronic Illness: Especially in immunocompromised individuals, the infection can become chronic and severe.
