What Happens If You Eat Bird Poop?

Bird droppings landing on an accidental spot can be annoying enough, but the thought of actually ingesting that bird poop may seem revolting. However, if it happened accidentally, you might wonder – what actually happens if a person eats bird feces?

If you’re short on time, here’s a quick answer to your question: Eating bird droppings could expose you to bacteria, fungi, or parasites that cause gastrointestinal illness. However, a small amount is unlikely to make a healthy person seriously sick.

In this comprehensive guide, we will cover the health risks of consuming bird poop, identify which birds’ waste is most hazardous, provide tips to prevent accidental ingestion, and explain what to do if it occurs.

Diseases or Parasites That Can Transmit


One of the potential risks of eating bird poop is the transmission of Salmonella bacteria. Salmonella is a common cause of food poisoning and can cause symptoms such as diarrhea, fever, and abdominal cramps.

It is important to note that not all birds carry Salmonella, but if the bird poop comes into contact with food or water that you consume, there is a risk of infection. It’s crucial to practice good hygiene and avoid consuming contaminated food or water.


Another disease that can be transmitted through bird poop is Campylobacter. This bacterium is commonly found in the intestines of birds and can cause gastrointestinal illness in humans. Symptoms of Campylobacter infection include diarrhea, nausea, vomiting, and abdominal pain.

It’s important to avoid direct contact with bird droppings and thoroughly wash your hands if you come into contact with them.


Giardia is a parasite that can be found in the feces of birds and other animals. If ingested, it can cause an intestinal infection called giardiasis. Symptoms of giardiasis include diarrhea, abdominal pain, bloating, and nausea.

It’s essential to avoid consuming contaminated water or food that may have come into contact with bird droppings to prevent giardia infection.


Cryptococcus is a type of fungus that can be found in bird droppings, particularly those of pigeons. Inhalation of the fungus can lead to respiratory infections in humans, especially in individuals with weakened immune systems.

Symptoms of Cryptococcus infection can include cough, chest pain, fever, and difficulty breathing. It’s important to avoid areas with high concentrations of bird droppings, especially if you have a compromised immune system.

Note: It is always recommended to consult a healthcare professional for proper diagnosis and treatment if you believe you have been exposed to any potential health risks.

Bird Droppings That Pose the Biggest Risk

Bird droppings can be a nuisance, but did you know that they can also pose health risks? While not all bird droppings are dangerous, there are certain types that you should be cautious of. In this article, we will explore the bird droppings that pose the biggest risk to human health.

Pigeon and chicken feces

Pigeon and chicken feces are commonly found in urban areas and can carry a variety of diseases. These droppings can contain harmful bacteria such as Salmonella and E. coli, which can cause serious gastrointestinal issues if ingested.

In addition, the spores of a fungus called Histoplasma capsulatum can be found in pigeon droppings, which can lead to respiratory problems if inhaled. It is important to avoid contact with these droppings and to clean up any areas that are contaminated.

Sea bird guano

Sea bird guano, or droppings, can be found in coastal areas and on islands where large colonies of seabirds nest. While the guano itself may not be harmful, it can attract other organisms such as fungi and bacteria that can cause health problems.

For example, exposure to the guano of certain seabirds, such as seagulls, can increase the risk of contracting diseases like Cryptococcosis, a fungal infection that primarily affects the lungs and central nervous system.

It is important to take precautions when visiting areas where sea bird guano is present.

Droppings from large flocks

Large flocks of birds, such as those found in parks or roosting areas, can produce a significant amount of droppings. These droppings can accumulate quickly and create unsanitary conditions. In addition to the health risks associated with the bacteria and fungi present in bird droppings, the droppings themselves can be slippery and pose a hazard, especially on walkways and stairs.

It is important to regularly clean up and remove droppings from areas frequented by large flocks of birds to maintain a safe and hygienic environment.

Remember, while bird droppings may seem harmless, certain types can pose a risk to human health. It is important to take precautions when dealing with bird droppings and to clean up any areas that may be contaminated.

If you have concerns about bird droppings in your area, consult with a professional wildlife control service for guidance on how to safely remove and prevent further contamination.

Symptoms of Sickness from Ingestion

Nausea and vomiting

One of the potential symptoms of ingesting bird poop is nausea and vomiting. When bird droppings are consumed, they can introduce harmful bacteria and parasites into the body, causing an upset stomach.

If you accidentally eat bird poop, you may experience feelings of queasiness followed by the need to vomit. This is your body’s natural defense mechanism to expel any harmful substances.

Diarrhea and abdominal cramps

Another common symptom of sickness from ingesting bird poop is diarrhea and abdominal cramps. The bacteria present in bird droppings can disrupt the normal balance of gut flora, leading to digestive issues. You may experience frequent loose stools and discomfort in the abdominal region.

It’s important to stay hydrated and seek medical attention if the symptoms persist or worsen.

Headache and muscle aches

Headache and muscle aches can also occur after ingesting bird droppings. Some bacteria found in bird poop can cause systemic infections, leading to flu-like symptoms. These may include headaches, body aches, and general fatigue.

If you develop these symptoms after consuming bird droppings, it’s crucial to consult a healthcare professional for proper evaluation and treatment.


Feeling fatigued and lacking energy is another possible outcome of eating bird poop. The presence of toxins and bacteria in bird droppings can impact your immune system, leading to a feeling of overall malaise.

If you notice a persistent tiredness or fatigue after ingesting bird droppings, it’s essential to rest and prioritize your health. Seeking medical advice is advisable if the fatigue persists or worsens.

It is crucial to note that ingesting bird droppings can be harmful to your health. If you accidentally consume bird poop or suspect you have, it’s important to seek medical attention promptly. While the symptoms mentioned above are potential outcomes, the severity and duration of symptoms may vary depending on the individual and the specific bacteria or parasites present in the droppings.

How Much Poop Causes Illness

When it comes to consuming bird poop, it is important to understand that there is no safe lower limit. Even a small amount of bird poop can potentially cause illness due to the presence of harmful bacteria and parasites.

It is always best to avoid direct contact or ingestion of bird droppings to minimize any potential health risks.

No safe lower limit

Unlike other types of animal waste, bird droppings can carry a variety of pathogens that can be harmful to humans. These include bacteria such as Salmonella and Campylobacter, as well as parasites like Cryptosporidium and Giardia.

These microorganisms can cause gastrointestinal issues, respiratory infections, and other health problems if ingested.

It is important to note that the concentration of pathogens in bird droppings can vary depending on various factors such as the bird species, diet, and overall health. Therefore, it is difficult to determine a specific safe lower limit for consuming bird poop.

Risk increases with volume consumed

The risk of illness from consuming bird droppings increases with the volume consumed. The more poop ingested, the higher the likelihood of coming into contact with harmful bacteria or parasites. This is why it is crucial to avoid any direct contact or ingestion of bird droppings, regardless of the amount.

Additionally, the risk may also be influenced by individual factors such as the person’s immune system strength and overall health. Individuals with weakened immune systems, such as the elderly or those with underlying health conditions, may be more susceptible to the pathogens present in bird droppings.

A small amount may not cause issues

While it is always best to avoid consuming bird droppings altogether, it is worth noting that a small amount of accidental ingestion may not necessarily cause immediate health issues. The human body has natural defense mechanisms to fight off certain pathogens, and the digestive system can often eliminate them without causing noticeable symptoms.

However, this does not mean that consuming bird poop is safe or recommended. It is still important to take precautions and practice good hygiene to minimize any potential health risks associated with bird droppings.
