Abstract
Foodborne pathogens such as parasites are acquired from raw foods like fruits and vegetables that are unhygienically prepared or unclean. One of the factors that can affect the fruit’s composition is the environment where it was processed and sold such as the local wet markets. The study used pre-cut and ready-to-eat fruits namely, Citrullus lanatus (watermelon) and Carica papaya (papaya), for these fruits are always available in markets and are being sold in sliced form. The sliced fruit samples obtained from stalls at Imus local wet market were soaked with saline solution, underwent centrifugation and added with Lugol’s iodine solution for viewing in microscope. Out of 150 slides, 4 Ascarid eggs were detected on sliced Citrullus lanatus samples while there is no seen parasitic organism in Carica papaya. Citrullus lanatus acquired 5.33% parasitic contamination while Carica papaya obtained 0% parasitic contamination. Citrullus lanatus has been proven to have higher parasitic contamination compared to the parasitic contamination of Carica papaya, considering the different possible factors such as their location of growth and the properties they contain.
