Abstract

Helminths eggs can spread rapidly in the environment due to climatic conditions and prolonged resistance to the environment. The objective of this study was to evaluate the presence of helminths eggs in supermarket carts of the municipality of Teresina, PI. This research was carried out in four large supermarkets during the months of june and july of 2016. The carts were randomly chosen and employed the adhesive tape method for the collection of the material. The tapes were fixed to the surfaces of the carts, then placed on glass slides, duly identified and taken to the Laboratory of Parasitology of the Department of Parasitology and Microbiology of the Federal University of Piauí. The analyzes were performed in optical microscopy, 10x and 40x objective. Of the analyzed 40 blades, 21 (52.5%) were positive for eggs of the Ascaris lumbricoides, Enterobius vermicularis, Trichuris trichiura and hookworms. Thus, it is possible to affirm the existence of helminth eggs in supermarket carts of Teresina, being the hands of the contaminated individuals that transit these places possible means of propagation of these parasites.
