Concerns About Eating Infested Walnut Paste: Health Risks and What to Do - Family Medicine

Share to:

The jujube walnut paste has insects, and I have consumed both the insects and their eggs?


On January 19th, around 5 PM, I opened a package of jujube walnut paste and after finishing it, I discovered a worm resembling a caterpillar in the corner of the bag (the head and tail are brown, the body is white, segmented, with evenly distributed small dots and some fuzz).
There were also white and brown insect eggs.
I would like to know if consuming the worm and the eggs could lead to the eggs hatching or concerns about parasitic infections in my body, and whether I need to go to the hospital for medical attention.

Hello, based on your description, the food has not been cooked, and it is unclear whether you have ingested it.
I recommend that you bring the photo along when you consult an infectious disease specialist, so the doctor can assess your current condition and determine if medication is necessary.
Thank you for your inquiry!

When it comes to concerns about consuming food that may be infested with insects, such as the walnut paste you described, it is understandable to feel anxious about potential health risks. In general, the ingestion of insects or their eggs is not uncommon in many cultures and is often considered safe, but there are some important factors to consider regarding your specific situation.

First, let's address the potential health risks associated with consuming insect-infested food. Most insects that might be found in food products, such as pantry moths or weevils, are not harmful to humans. They do not carry diseases that can be transmitted to humans, and the likelihood of their eggs hatching and causing a parasitic infection in your body is extremely low. The human digestive system is quite effective at breaking down food, including any insects or eggs that may be ingested. In most cases, these will simply pass through your system without causing any harm.

However, there are exceptions. Some insects can carry pathogens or bacteria that could lead to foodborne illnesses, particularly if the food was already contaminated before the insects were present. If the walnut paste was stored improperly or was past its expiration date, there could be a risk of contamination from other sources, not just the insects themselves. Symptoms of foodborne illness can include nausea, vomiting, diarrhea, and abdominal pain, which typically arise within hours to a few days after consuming contaminated food.

If you have already consumed the walnut paste and are not experiencing any immediate symptoms, there is likely no cause for alarm. However, if you begin to feel unwell, it would be wise to seek medical attention. A healthcare professional can provide guidance and may recommend tests if necessary.

In terms of prevention, it is essential to inspect food products before consumption, especially if they are stored for an extended period. Look for signs of infestation, such as holes in packaging, visible insects, or unusual odors. Proper storage of food items in airtight containers can help prevent infestations.

If you find yourself in a similar situation in the future, here are some steps you can take:
1. Do Not Panic: Understand that while it is unpleasant to consume insects, the risk of serious health issues is generally low.


2. Monitor Your Health: Keep an eye on any symptoms that may arise after consumption. If you experience gastrointestinal distress, consult a healthcare provider.

3. Seek Medical Advice if Necessary: If you have concerns about potential parasitic infections or if symptoms develop, do not hesitate to seek medical attention.

4. Practice Good Food Safety: Always check food products for signs of spoilage or infestation before consuming them. Store food in sealed containers to minimize the risk of pests.

In conclusion, while the experience of consuming insect-infested walnut paste is certainly unsettling, the actual health risks are minimal. Your body is well-equipped to handle such occurrences, and with proper food safety practices, you can reduce the likelihood of similar situations in the future. If you have further concerns or develop symptoms, consulting a healthcare professional is always a prudent choice.
