Evaluation of two analytical methods of detection for intestinal parasites in curly lettuce sold in food stalls

Abstract This study aimed to investigate the occurrence of parasitic structures in curly lettuce (Lactuca sativa L.) sold food stalls open markets Cuiabá city, Brazilian state Mato Grosso (MT). For this purpose, 50 samples were evaluated using spontaneous sedimentation and centrifugal flotation methods. These techniques showed positivity 96% (48/50) 78% (39/50) samples, respectively. The method was statistically (p ? 0.05) more effective detecting pathogens as Entamoeba histolytica, Ascaris spp., Strongyloides Larvae Hookworm eggs, when comparing both However, these methods did not differ significantly for detection Giardia lamblia. spp coli occurred 64% (32/50) 46% (23/50) positive respectively, with highest percentages observed. Blastocystis Fasciola Dipylidium caninum lumbricoides revealed exclusively by method, while Iodamoeba butschlii Enterobius vermicularis detected centrifugal– procedure. results could reinforce need use based on fluctuation parasite analysis lettuce. presence parasites fecal origin, recognized pathogenicity, represents a risk consumer health demonstrates deficit good agricultural practices production, distribution commercialization
