Food forms an integral part of health in our day-to-day life, although sometimes contaminated, raw, or undercooked food could lead to parasitic infection in individuals. There are some types of worms that infect humans through contaminated food or water containing parasite eggs or larvae in their various developmental stages.

Not all cases of digestive ailments are associated with worm infection, and consuming certain foods does not necessarily result in parasitic infection. However, it helps when one is aware of the types of foods and the handling techniques that could make one susceptible to foodborne parasites.

The following article discusses how food contributes to worm infection, the foods that need to be handled with extra care, and the preventive measures.

How Can Food Cause Worm Infections?

Parasites such as worms may sometimes enter the human body through contaminated food.

This usually occurs either due to the presence of parasite eggs and larvae in the food, or because meat or fish consumed by humans was undercooked and therefore contained some parasites.

There is also the possibility of contamination when food is prepared with unwashed hands or on contaminated surfaces, as well as the use of unsanitary water.

Foodborne parasitic infection may differ in terms of affected organs, as some parasites affect the digestive tract only, while others cause infections of non-intestinal organs.

The crucial factor is that food is not the only way of being affected by parasites; there are several other ways of spreading the disease as well.

Which Foods May Increase the Risk of Parasites?

All foods are not equally dangerous. Different aspects of handling, storing, preparing, and cooking the food may influence the risk.

1. Raw or Undercooked Meat

There are parasitic diseases related to the consumption of raw or partially cooked meat. Pork, beef, and other types of meat may have parasites in case of poor safety of foods. Cooking meat is the best way to minimize the risks of parasites in food.

2. Raw or Undercooked Fish

There are some parasites that can be transmitted by consumption of raw or partially cooked fish. This is especially important when eating some particular raw fish dishes.

Food safety rules should be taken into account by those people who eat raw or partially cooked seafood often.

3. Raw or Undercooked Shellfish

Shellfish may be contaminated based on the environmental conditions in which they are caught and kept.

Cooking shellfish is an important step for minimizing the risks of infection.

4. Unwashed Fruits and Vegetables

Fruits and vegetables might get parasite eggs or any other pathogens from the soil or water, improper handling, or by coming into contact with contaminated objects.

Proper washing of produce before consumption will ensure that there is no dirt.

5. Food Prepared With Unsafe Water

Water may also be responsible for spreading parasitic diseases. Contaminated water can contaminate food products that have been washed, prepared, or watered.

Therefore, the use of safe drinking water in cooking and washing of produce is very crucial when it comes to food hygiene practices.

6. Foods Handled With Poor Hygiene

Food that was initially free of any contaminants can get contaminated during processing.

This might happen if you touch food with your hands that were not washed, use improperly cleaned utensils, or prepare cooked food on the same plate that had raw meat on it.

Can Cooking Kill Parasites?

Cooking can effectively eliminate most parasites found in food. However, proper cooking methods and temperatures differ depending on the kind of food and parasite being considered.

Therefore, it would be wise to take into account the food-safety guidelines instead of the appearance of the food only.

In other words, meat must be cooked correctly, seafood should be prepared properly, and foods meant to be consumed without cooking should be sourced from places that have the appropriate safety measures.

Another possible way to control the parasites in food is through freezing, although it is not applicable for all kinds of parasites or foods.

7 Ways to Reduce Your Risk of Foodborne Parasites

Simple food-safety habits can make a meaningful difference.

1. Wash Your Hands

Thoroughly wash your hands using soap and water prior to handling or eating food, as well as after handling raw meat, using the toilet, or touching any surfaces that might be contaminated.

2. Wash Fresh Produce

Fruits and vegetables should be rinsed with clean running water before eating or cooking them.

3. Cook Meat and Seafood Properly

Eat cooked meats or seafood only when you can ensure that they are properly cooked in order to eliminate any possible parasites.

4. Keep Raw and Cooked Foods Separate

It is advisable to use different utensils during food preparation to prevent cross-contamination of cooked foods by using utensils that have been used for raw meat or seafood.

5. Use Safe Water

Use safe drinking and cooking water, particularly when travelling or when the local water supply may be contaminated.

6. Store Food Correctly

Store food at correct temperatures and avoid keeping cooked food for a long period of time at room temperature.

7. Choose Food From Reliable Sources

Purchase your meat, seafood, and other foods from a reputable supplier.

What Are the Symptoms of a Worm Infection?

They will differ depending on the type of worm and the location in the body. Some individuals may not experience any symptoms, while others may develop digestive or non-specific symptoms.

Possible symptoms include:

● Abdominal discomfort or pain

● Diarrhoea

● Nausea

● Changes in appetite

● Unexplained weight loss

● Fatigue

● Bloating

● Itching around the anus in some infections

● Visible worms or worm segments in stool in certain cases

These symptoms are common with worm infections but could be linked to many other digestive illnesses; therefore, making the diagnosis solely based on symptoms impossible.

However, if they are persistent or severe and follow a worm exposure, medical attention should be sought.

How Are Worm Infections Diagnosed?

The signs and symptoms of the disease, the recent travel history, the patient’s diet, and the patient’s medical history may also be considered by a healthcare professional.

Based on the suspected infection, there may be stool samples analyzed, blood tests performed, and imaging conducted.

It is important to identify the specific parasite because different infections may need to be treated differently.

How Are Parasitic Worm Infections Treated?

The treatment will depend on the kind of parasite involved, the site of the infection, the degree of severity of the symptoms, and the specific conditions of the person.

Some worm infections in humans can be treated with medicines known as anthelmintics. One such medicine is Fenbendazole 500 mg, and it is used for some parasitic worm infections in humans. The medication has to be used under medical prescription since the treatment and the dosage may differ depending on the type of infection.

It is important to know how human medications differ from veterinary medications.

For instance, Mebendazole 100 mg is an anthelmintic used mainly in veterinary treatment. It should not be regarded as an established and approved treatment for worm infections in humans; people should not use veterinary drugs instead of human ones.

This is especially important when one comes across information on treatments for parasites online. Just because a medicine has been researched or discussed for some purpose does not mean that it is proven to be effective or safe for that purpose.

Can Food Alone Get Rid of Worms?

Although some foods might be nutritious and contribute to good health, there is no known effective food therapy for parasitic worm infections that can be used instead of an appropriate treatment of the disease.

Garlic, pumpkin seeds, papaya seeds and other such foods are often recommended online as a means of natural remedy for parasitic worm infections. Nevertheless, consuming such foods cannot be regarded as the same as taking an appropriate treatment.

A healthy diet will help maintain good health, but a suspected parasitic infection must be evaluated depending on the parasite.

Who Should Take Extra Care?

Some people may need to be particularly careful about food hygiene and parasite exposure, including people who:

● Travel to areas where certain parasites are more common

● Regularly consume raw or undercooked foods

● Work with animals or contaminated soil

● Have frequent exposure to potentially contaminated water

● Have a weakened immune system

Following basic hygiene and food-safety practices can reduce unnecessary exposure.

When Should You Speak With a Healthcare Professional?

Seek medical help in case you experience digestive problems, weight loss, prolonged diarrhea, abdominal pain, and any other symptom of concern.

It is also helpful if you suspect infection with a certain type of parasitic worm or observe anything unusual in your stool.

Do not make a diagnosis yourself based only on what you learn online since there is a whole range of treatments for different parasites and there are symptoms of non-parasitic origin as well.

The Bottom Line

The other method whereby parasites may enter the human body is through food. This happens especially if food is not prepared properly, eaten raw, or if it is contaminated in any way. However, there are various methods by which one can reduce such risks to a minimum.

Wash fruits and vegetables, cook food in proper ways, handle raw and cooked food separately, use clean water, and practice proper hand washing. If a worm infection is suspected, seeking professional advice may help in determining the type of worm involved and the course of action to be taken.

Above all, avoid using food remedies or animal medicines for treating worm infections in humans.
