Risk can be higher when vegetables:

• Are grown using contaminated water
• Come into contact with contaminated soil
• Are exposed to animal waste
• Are harvested under poor sanitary conditions
• Are washed with unsafe water
• Are eaten raw without adequate preparation

The risk also depends heavily on the specific organism involved.

What Is Fasciola?

Fasciola is a type of parasitic flatworm commonly known as a liver fluke.

Humans can become infected by consuming infectious stages of the parasite, traditionally associated with contaminated freshwater plants.

Once inside the body, the parasite can migrate through tissues before reaching the bile ducts, where adult worms can live.

The infection is known as fascioliasis.

It occurs in various parts of the world, particularly in areas where people may consume raw aquatic plants and where livestock and contaminated freshwater environments are common.

Importantly, not every parasite-related outbreak associated with vegetables involves Fasciola. Different parasites have different transmission routes.

That is why a specific outbreak should be evaluated based on laboratory and epidemiological evidence rather than a social-media image alone.

What Symptoms Can Occur?

Symptoms depend on the parasite and the stage of infection.

With fascioliasis, some people may experience symptoms such as:

Abdominal pain

Fever

Nausea

Vomiting

Diarrhea

Loss of appetite
