Abstract

Parasite analysis in lettuce from street markets is a crucial practice to ensure food safety and public health. Lettuces that are frequently consumed raw can be sources of contamination by several parasites, including protozoa of the genus Entamoeba. Detection of these parasites is essential to prevent disease outbreaks and protect the health of consumers. The study aims to investigate the presence and quantity of protozoa of the genus Entamoeba in samples of lettuce sold at street markets in two cities in the upper backlands, using the Hoffman method to qualify the protozoa present. Detection includes ensuring safe food, protecting the health of the population, complying with regulatory standards, implementing appropriate agricultural practices, and promoting education and awareness. Of the samples analyzed, 65% had protozoa of the genus Entamoeba, indicating a high prevalence in lettuce from street markets during the study. The data highlight the need for further studies on Entamoeba contamination in food washing water. Although microscopy and concentration techniques are effective, further research is needed to improve the sensitivity and specificity of these methods.
