Fresh vegetables are widely considered one of the healthiest foods people can eat, but experts warn that some raw vegetables may also carry hidden parasites if they are not cleaned properly before consumption.
A recent study examining hundreds of fresh vegetable samples found that several commonly eaten vegetables showed signs of parasite contamination, raising concerns among people who regularly consume raw salads, herbs, and uncooked greens.
Among the vegetables tested, celery ranked among the highest for parasite contamination. Researchers explained that vegetables with:
- layered leaves,
- uneven surfaces,
- or close contact with soil
can more easily trap:
- parasite eggs,
- bacteria,
- and microscopic contaminants.
Health specialists say parasites may enter vegetables through:
- contaminated water,
- untreated fertilizer,
- poor handling during harvesting,
- or unsanitary storage conditions.
According to experts, some parasites linked to poorly washed produce may affect the digestive system and, in rare severe cases, potentially spread to other organs if left untreated.
