Intestinal parasites infection, a serious public health problem, can be transmitted by ingestion contaminated food and inadequate hygiene habits. Therefore, birds and those handling the birds can be parasites propagation means. The aim of this study was to investigate the prevalence of parasitic infections in poultry workers who parasitological examinations (EPF) periodically. The collection was made in the database of EPF results for the years 2011 and 2012 in a laboratory of Caxias do Sul, Rio Grande do Sul, Brazil. In the 446 samples evaluated in 2011, we observed the presence of parasites in 15.9% of samples, with 9.41% infected Endolimax nana; 2.91% Entamoeba coli; 2.24% Giardia lamblia; 0.45% Iodamoeba butschlii, 0.22% Strongyloides stercoralis and 0.67% for multiple worms. In the year 2012, 187 samples, which also observed a higher incidence of protozoan cysts with 9.09% of Endolimax nana, 2.67% Entamoeba coli, 1.07% Giardia lamblia and 1.06% infected by more than one parasite. Infected workers can be a source of contamination food and parasites dissemination. Faced with this, it emphasizes the importance of periodic stool examinations in workers involved in the handling and distribution of food, as a way to reduce or cure the current contamination.
