Abstact: This study aimed to analyze the parasitological profile of lettuces sold at markets in the city of
São Luís, Maranhão. A total of 44 lettuce samples from different stalls of the selected markets
were collected and analyzed in a laboratory to detect the presence of parasites. The analysis of
the samples was carried out at the Human Parasitology Laboratory (LPH) of the State
University of Maranhão. The lettuces were then de-leaved and washed with a solution of 10
mL of Triton X-100 detergent in 250 mL of water. Subsequently, the water resulting from the
wash was filtered and centrifuged at 3,500 rpm for 5 minutes, and the sediment was removed
using a Pasteur pipette, placed in Falcon tubes, and stored under refrigeration at 23°C until the
time of analysis. The results showed that 70,4% of the samples were contaminated with some
form of parasites. Of these, 56% were detected with the occurrence of helminths, 6.8% with
protozoa, 65.9% with other organisms such as insects and mites. Meanwhile, 11.3% had
structures of eggs from unidentified organisms. Among the observed helminths, the highlighted
parasites were Ancylostoma spp., Hymenolepis spp., Enterobius vermicularis, Strongyloides
spp., Toxocara canis, Taenia spp., and Habronema spp. As for protozoa, Eimeria spp. was
noted. Other organisms were also detected, such as mites, insects, and algae. Thus,
Ancylostoma spp. and Hymenolepis spp. were the most frequently found helminths. According
to the results, to minimize these risks, it is essential to implement effective hygiene and
sanitation practices at markets and in food production and handling areas. This includes
properly washing vegetables, using clean equipment and utensils, and correct handling of food.
Furthermore, it is important for consumers to also take steps to ensure food safety, such as
washing vegetables before consuming them. In this way, the results of this study highlight the
importance of implementing effective hygiene and sanitary practices to ensure the food safety
of consumers and minimize the risks associated with the consumption of contaminated
