This is especially worrisome in the Buea Health District of South West Cameroon,where farming methods and environmental factors may increase the risk of infection. This study fills the gap in localresearch on parasitic infection in this region.

Objective: To examine the occurrence of intestinal parasites in leafy vegetables sold in major markets of the BueaHealth District, revealing regional patterns of contamination and factors that affect them.

Methodology: A descriptive cross-sectional survey sampled vegetables from five main markets in the Buea HealthDistrict. Standard parasitological techniques were used to analyze 75 vegetable samples. The study used stratifiedrandom sampling to account for different vegetable types.

Results: The vegetable samples had an intestinal parasite prevalence of 2.7%. The parasites were distributeddifferently among various vegetable types and market locations, showing the impact of certain environmental andagricultural factors.

Conclusion: The study found a fairly low occurrence of intestinal parasites in the vegetables sampled, indicatingthat the current agricultural and hygiene practices in the region are working well. However, differences incontamination among different markets and vegetable kinds highlight the importance of specific public healthactions and ongoing surveillance.
