Parasitic worms, also known as helminths, are large macroparasites, which as grown-ups are large and can be viewed with the exposed eye. A number of them are intestinal worms that are soil-transmitted and infect the gastrointestinal tract. On the other hand, vegetables are cheaper and rich source of vitamins. However, because of the complexity of their surfaces, ingestion of raw vegetables presents an important mean of transmission of several infectious diseases. Cabbage, cauliflower and lettuce are some of the most consumed and commonly sold vegetables in public market that make these as possible vessels for parasitic contamination. This research generally aimed to detect and identify the parasitic helminth ova that are present in the three vegetables. The samples were collected and washed with normal saline solution. The solution was transferred on test tubes then underwent centrifugation. Six (6) slides were prepared from each sample and were examined under a light microscope with Lugol’s iodine solution. Out of all the samples’ replicates, 7.4% were positive of parasitic helminth ova. Results from the three markets showed that there is no presence of parasitic helminth ovum on cabbage but was present on cauliflower and lettuce.
