“…The low occurrence of helminths in relation to protozoans observed in the present study, as also found by other investigators 3,13,20 , may indicate changes in the profile of intestinal parasites. This difference may be related to the use of self-medication for helminths, which may fail to eliminate protozoans and also lead to the appearance of immune-mediated diseases (colitis, reactive airway disease, encephalitis and diabetes), since the loss of natural helminth exposure removes a universal Th2 and regulatory immune effect imparted by these organisms (ELLIOTT et al 6 ; MULCAHY et al 11 ).…”

“…Overall, E. nana and E. coli were the predominant species, as found in previous studies 4,13,25 . E. nana predominated among cooks and kitchen helpers, bakers and confectioners, and school food servers; whereas B. hominis predominated among mobile vendors.…”

“…The higher occurrence of these two species may also be related to the fact that the presence of cysts of these protozoa in human feces does not mean that the host needs to be treated. According to NOLLA & CANTOS 13 , although E. nana and E. coli are not pathogenic in humans, their high rate of occurrence in food handlers is worrisome because these are risk groups for transmitting other pathogenic species. B. hominis, although its pathogenicity is controversial, was the third most frequent species, and it is often reported in food handlers 2,13,19 .…”

“…Food-borne diseases extend beyond the domestic environment, affecting increasing numbers of people and representing an important public-health problem in all countries 4,13 . Growing urbanization and lifestyle changes lead people to dine away from home more often, contributing to the unregulated opening of eating establishments that often have inadequate hygiene conditions.…”

“…Food handling is one form of dissemination of pathogens 28 , because inadequate hygiene habits, such as the lack of regular hand washing, allow mainly asymptomatic carriers of diseases, including enteroparasitosis, to contaminate the food that they handle 25 . Although it is recognized that locations where large numbers of meals are prepared are more subject to the occurrence of food-borne illnesses, and in spite of the importance and topicality of the subject, few researchers have investigated food services 14 and the presence of enteroparasites in food handlers 4,13,20 .…”

SUMMARYThis study reports on the occurrence of enteroparasites based on data from an ethnographic study of food handlers in the city of Cascavel, Paraná, Brazil. Fecal material from 343 food handlers of both sexes, between 14 and 75 years of age, was analyzed using Lutz, modified Ritchie and Ziehl-Neelsen techniques. Ethnographic relationships were investigated by means of specific questionnaires. Positive fecal samples were found for 131 (38.2%) handlers. Endolimax nana (67.9%) was the predominant species, followed by Entamoeba coli (35.9%), Blastocystis hominis (28.2%), Entamoeba histolytica/dispar (10.1%) and Giardia duodenalis (8.4%). Protozoan infections were more common than helminth infections (p = 0.00). The positive results for some parasites were associated with the male sex, professional category, and the performance of other activities (p ≤ 0.05). The high overall occurrence of enteroparasites found indicates improper hygiene and sanitation conditions. Effective educational measures should be implemented to prevent the transfer of pathogenic organisms to food via handling.

The objective of this review was to outline an epidemiological profile of Strongyloides stercoralis by parasitological and serological diagnosis in inhabitants, and to associate this profile with different immunosupression situations, in Brazil, over 20 years (1990-2009). The occurrence of S. stercoralis using parasitological methods was 5·5%, being 4·8% in rural and 5·0% in urban areas, characterizing the country as hyperendemic. There was a diversity of techniques used as a diagnostic tool and only 39·1% of the studies presented results based on at least 1 specific method. The occurrence increased with age, being 12·1%, for those over 60 that suggests an epidemiological condition of concern for the elderly population. Of the seroepidemiological studies in the general population the mean positivity in serum samples was 21·7% and 29·2%, using an immunofluorescence antibody test and enzyme-linked immunosorbent assay (ELISA), respectively. The occurrence of strongyloidiasis in immunosuppressed individuals was 11·8% by parasitological methods and 19·5% using immunological methods. Considering that Brazil is a tropical country and that the character of chronicity and autoinfection of the parasite that can result in severe forms of hyperinfection or dissemination makes strongyloidiasis an important medically and socially neglected problem.

In this study, the prevalence and risk factors for enteroparasites were determined in food handlers from Maringá, Paraná State, southern Brazil. Fecal and subungual materials of 150 street food vendors were analyzed by the methods of Lutz, Faust, and Mello, respectively. A questionnaire on hygiene and sanitary conditions of the workplace and of domicile was applied. The prevalence of enteroparasites was 28%, and the protozoa infection was more expressive (21.3%) than by helminths (6.7%), but without significant difference (p > 0.05). Entamoeba coli was the most frequent species occurring in 15.3%, while the prevalence of protozoa pathogenic was low (Giardia lamblia: 2.7% and Entamoeba histolytica: 0.7%). The subungual material presented negative results. The presence of pets in domiciles has increased twice the risk of infection. The working conditions of the majority of street food vendors were inappropriate. The results highlight the need for more rigorous programs of continuing education, parasitological examination every six months, and health surveillance. In this way, the quality of the service provided to the population can be improved and the transmission of food-borne diseases can be prevented.
