Abstract

Soil-transmitted helminths (STH), also known as intestinal nematodes, require soil to reach the infective stage, commonly including Ascaris lumbricoides (giant roundworm), Trichuris trichiura

(whipworm), Hookworm. The main purpose of the study is to determine the presence of Soil- transmitted helminths in Lactuca sativa (Lettuce) and Brassica oleracea var. capitata (Cabbage) from

Kadiwa and Central Market in Dasmariñas, Cavite. In addition to that, the researchers utilized a descriptive method and sedimentation technique to identify the STH present in the said vegetables. The results showed that 13 STH are present in Kadiwa Market and 18 STH in Central Market out of the 70 samples tested from each market. The most common STH seen in both markets is the Ascaris lumbricoides egg. While there is a presence of STH from the samples, there is no significant association between L. sativa and B. oleracea var. capitata samples and parasite detection, and no significant association between market source (Kadiwa and Central Market) and parasite detection.

Results indicates that there is insufficient evidence that one vegetable type is more likely to contain parasite than the other, and not enough evidence to say that vegetables from one market are more likely to have parasites than those from the other. Further studies are necessary for the establishment of a well-grounded information leading to a better understanding regarding food safety awareness.
