Frequency of intestinal parasites and commensals in street waste pickers from two cooperatives in the Brazilian Federal District

ABSTRACT

This study describes the occurrence of intestinal parasites and commensals among street waste pickers (SWPs) of two cooperatives of recyclable materials in the Federal District, Brazil. Stool samples from 75 individuals were analyzed using the Rugai method and spontaneous sedimentation. A questionnaire was applied to assess the awareness of SWPs regarding diseases caused by garbage handling and their prevention methods. Sixty SWPs (80%) were diagnosed with intestinal helminths or protozoa. The most frequent protozoa found were Entamoeba coli (43%), Endolimax nana (28%), and Entamoeba hartmanni (15%), and helminths such as Ascaris lumbricoides (12%), hookworms (8%), and Strongyloides stercoralis (8%) were also found. Other species identified in the workers were E. histolytica/dispar (8%), Giardia lamblia (7%), Hymenolepis diminuta (3%), and Hymenolepis nana (3%). Thirty nine SWPs (65%) had mixed infections. Most (80%) SWPs reported having parasitic diseases in the past, and 72% reported having undergone a stool test. All individuals considered important to use personal protective equipment but only 40% wore gloves. The adoption of healthy hygiene habits and the proper use of personal protective equipment should decrease the occurrence of intestinal parasites in these individuals
