Eating undercooked pork?


In October 2021, I ate undercooked pork chops at a teppanyaki restaurant.
Over the past few months, I have frequently experienced itching in my buttocks, increased episodes of diarrhea, and sometimes abdominal cramps.
I'm unsure if these symptoms are related to the vaccine I recently received, as I occasionally feel chest pain.
When I experienced chest pain, I went to the emergency room, where they performed an electrocardiogram (ECG) and blood tests.
The ECG did not indicate myocarditis, and the blood tests did not show signs of a myocardial infarction.
Could this be due to a pork tapeworm? If so, which specialty should I consult and what tests should I undergo to confirm this?

Hello, based on your description, the main concern is diarrhea and the possibility of a parasitic infection.
It is recommended to visit a gastroenterologist or a family medicine physician to arrange for a stool test to check for any eggs.
If none are found, the likelihood of a parasitic infection should be low.
It is more likely that the symptoms are due to vaccine side effects.
Thank you for your inquiry.

More Info


When it comes to undercooked pork, there are several health risks associated with consuming it, primarily due to the potential for parasitic infections, such as those caused by the pork tapeworm (Taenia solium) and other pathogens like Trichinella spiralis. These parasites can lead to serious health issues, including gastrointestinal disturbances and systemic infections.

Given your symptoms—itchiness, frequent diarrhea, abdominal cramps, and occasional chest pain—it's understandable to be concerned about the possibility of a parasitic infection. The symptoms you describe could potentially be linked to a few different conditions. For instance, if you indeed contracted a pork tapeworm, you might experience gastrointestinal symptoms, but the systemic symptoms like chest pain are less common and could be attributed to other factors, including anxiety or reactions to the vaccine you mentioned.

To address your concerns, it is crucial to seek medical attention. The appropriate specialist for your situation would be a gastroenterologist, as they can evaluate your gastrointestinal symptoms and determine if further testing is necessary. Tests that may be conducted include stool examinations to check for the presence of eggs or larvae from parasites, blood tests to identify any signs of infection, and imaging studies if needed to assess for any complications.

In addition to the gastroenterology consultation, if you continue to experience chest pain, it would be wise to follow up with a cardiologist, especially since you have already had an ECG and blood tests that ruled out acute cardiac issues. Persistent chest pain should never be ignored, and further evaluation may be warranted to ensure that there are no underlying cardiac conditions.

It's also important to consider the timeline of your symptoms. If they began shortly after consuming undercooked pork, it could suggest a direct link. However, if the symptoms have persisted for several months, it may indicate that there are multiple factors at play, including possible post-vaccination effects or other gastrointestinal issues unrelated to the pork consumption.

In summary, your next steps should include:
1. Consulting a gastroenterologist: They can evaluate your gastrointestinal symptoms and perform necessary tests to check for parasitic infections or other gastrointestinal disorders.


2. Monitoring your symptoms: Keep a detailed record of your symptoms, including their frequency, duration, and any potential triggers, which can help your healthcare provider make a more accurate diagnosis.

3. Seeking a cardiology evaluation: If your chest pain persists or worsens, it is essential to consult a cardiologist to rule out any cardiac issues.

4. Practicing safe food handling: To prevent future incidents, ensure that all pork and other meats are cooked to safe internal temperatures (145°F for pork, followed by a three-minute rest time) to eliminate the risk of foodborne illnesses.

By taking these steps, you can better understand your health concerns and receive appropriate care. Remember, it's always better to err on the side of caution when it comes to your health, especially with symptoms that could indicate a more serious condition.
