| dc.description.abstract | The main purpose of this study is to assess parasitic contamination in lettuce (Lactuca
sativa) vegetables obtained from selected public markets in Davao City. This study made use of a quantitative quasi-experimental cross-sectional research design to investigate parasitic contamination in Agdao, Bankerohan, and Toril Public Markets. A
total of sixty samples were purchased, placed in sterile plastic bags, and transported to
the University of Mindanao Medical Technology Laboratory. Each sample was washed
individually with saline, and a simple wet mount technique was used to detect parasites after overnight sedimentation. Upon microscopic examination, findings of the study revealed that out of 60 lettuce samples examined, four were positive for parasites, corresponding to a total prevalence of 6.67 percent. The parasites identified
were Strongyloides stercoralis, Balantidium spp., filariform larva, and trematode egg.
It was also found that there is no significant difference between parasitic contamination among the three public markets. Based on the findings of this study, the researchers conclude that the presence of parasites in lettuce vegetables poses a high risk to food safety. Hence, the researchers recommend that health agencies in the community educate vendors, food handlers, consumers, and the public about the proper washing of lettuce and other leafy vegetables before consumption to prevent possible outbreaks of parasitic infections in the future. | en_US |
