Accidental Ingestion: What Symptoms to Watch For After Tasting Unknown Liquid - Internal Medicine

Ingestion issues?


Hello, doctor.
This morning I saw brown droplets on my desk and mistakenly thought it was a spilled drink, so I dipped my finger in it and put a little in my mouth to taste.
However, after tasting it, I realized it had a strange flavor and suspected it might be mouse urine.
At that moment, I drank a lot of water to dilute it.
What symptoms should I watch for in the coming days?

Hello, animal waste may contain some infectious agents, such as Leptospira, which can cause symptoms like fever and general malaise, as well as gastrointestinal discomfort such as nausea, diarrhea, and abdominal pain.
If you are experiencing any discomfort, you can consult a family medicine specialist.
Thank you for your inquiry.

More Info


Accidental ingestion of unknown substances can be concerning, especially when there is a suspicion that the substance may be harmful, such as rodent urine. While it is good that you acted quickly by drinking water to dilute the substance, it is important to be aware of potential symptoms that may arise in the following days.

First and foremost, rodent urine can carry various pathogens, including hantavirus and leptospirosis, which can lead to serious health issues. However, the risk of transmission through a small amount of accidental ingestion is generally low, especially if you did not consume a significant quantity. Here are some symptoms to watch for in the coming days:
1. Gastrointestinal Symptoms: Monitor for any signs of nausea, vomiting, diarrhea, or abdominal pain. These symptoms could indicate irritation of the gastrointestinal tract due to the substance ingested.

2. Fever and Chills: If you develop a fever, chills, or body aches, it could indicate an infection. This is particularly important to note if you experience these symptoms in conjunction with other gastrointestinal issues.

3. Respiratory Symptoms: Although less common, exposure to rodent urine can sometimes lead to respiratory issues. Watch for symptoms such as coughing, difficulty breathing, or chest pain.

4. Neurological Symptoms: In rare cases, exposure to certain pathogens can lead to neurological symptoms such as headaches, confusion, or dizziness. If you experience any of these, seek medical attention promptly.

5. Urinary Symptoms: Since you suspect the liquid may have been rodent urine, be aware of any changes in urination, such as increased frequency, urgency, or pain during urination.

If you notice any of these symptoms, it is advisable to seek medical attention. A healthcare professional may recommend tests to rule out any infections or other complications. Additionally, if you have any underlying health conditions or a compromised immune system, it is particularly important to consult a doctor.

In the meantime, continue to stay hydrated and monitor your health closely. Keeping a record of any symptoms that develop can be helpful for your healthcare provider if you need to seek medical attention.

Lastly, for future reference, it is crucial to avoid tasting or ingesting unknown substances, as this can pose significant health risks. If you suspect that a substance may be hazardous, it is best to err on the side of caution and consult with a professional before taking any action. If you have any further concerns or questions, do not hesitate to reach out to a healthcare provider for personalized advice.
