ABSTRACT
Parasitic infection is highly prevalent throughout the developing countries of the world. Food handlers are a potential source of infection for many intestinal parasites and other enteropathogenic infections as well. The aim of this study was to determine the prevalence of intestinal parasite carriers among food handlers attending the public health center laboratory in Sari, Northern Iran for annual check-up. The study was performed from August 2011 through February 2012. Stool samples were collected from 1041 male and female food handlers of different jobs aged between 18 to 63 years and were examined following standard procedures. Sociodemographic, environmental and behavioral data analysis of the food handlers were recorded in a separate questionnaire. Intestinal parasites were found in 161 (15.5%) of the studied samples. Seven species of protozoan or helminth infections were detected. Most of the participants were infected with Giardia lamblia (53.9%) followed by Blastocystis hominis (18%), Entamoeba coli (15.5%), Entamoeba histolytica/dispar (5.5%), Cryptosporidium sp. (3.1%), Iodamoeba butschlii (3.1%) and Hymenolepis nana (1.9%) as the only helminth infection. The findings emphasized that food handlers with different pathogenic organisms may predispose consumers to significant health risks. Routine screening and treatment of food handlers is a proper tool in preventing food-borne infections.
RESUMO
Infecção parasitária é altamente prevalente entre os países em desenvolvimento do mundo. Manipuladores de alimentos são fonte potencial de infecção de muitos parasitas intestinais assim como de outras infecções entero-patogênicas. O propósito deste estudo foi determinar a prevalência de portadores de parasitas intestinais entre pessoas que manipulam alimentos e atendem o centro de saúde pública em Sari, norte do Iran para possível check-up. O estudo foi conduzido de agosto de 2011 até fevereiro de 2012. Amostras de fezes foram coletadas de 1041 manipuladores de ambos os sexos e de diferentes funções entre a idade de 18 e 63 anos e foram examinados de acordo com procedimentos standard. Em questionário separado foram colocadas as análises sóciodemográficas, ambientais e de comportamento dos manipuladores de alimentos. Parasitas intestinais foram encontrados em 161 (15,5%) das amostras estudadas. Sete espécies de protozoários ou infecções por helmintos foram observadas. A maior parte dos participantes estava infectada com Giardia lamblia (53,9%) seguida por Blastocystis hominis (18%), Entamoeba coli (15,5%), Entamoeba histolytica/dispar (5,5%), Cryptosporidium sp. (3,1%), Iodamoeba butschlii (3,1%) e Hymenolepis nana (1,9%) como a única infecção por helminto. Os achados enfatizaram que os manipuladores de alimentos, com diferentes organismos patogênicos podem se constituir risco significante para os consumidores. Exames rotineiros e tratamento dos manipuladores de alimentos são as ferramentas apropriadas para prevenir as infecções originadas de alimentos.
