Parasitic diseases are among the most important infectious diseases and pose health problems in many countries, most especially in developing countries. Workers at food centers could transmit parasitic infections in the absence of sanitation. This is a descriptive study conducted to determine the prevalence of intestinal parasitic infections in food clerks in the city of Tabriz in 2014. Data was recorded in the offices of the health center for all food handlers who were referred to the laboratory for demographic and stool tests to receive the health card. Parasitic infection was observed in 172 cases (3.73%) of 4612 samples. A total of 156 positive samples (90.69%) were related to protozoa and 16 (9.3%) were related to helminthes. Most of the parasitic infections were related to Giardia and Entamoeba coli and the lowest infection was related to H. nana. Also, there was a significant relationship between level of education and parasitic infection rate (P = 0.0044). But there was no significant difference between the type of infection and amount of intestinal parasites. The results show that the prevalence of intestinal parasites, especially pathogenic protozoa, is common in some food handlers. Therefore, more sanitary controls are required and increasing of education will play a crucial role in improving the health of these people.
寄生虫病是最重要的传染病之一，在许多国家，尤其是发展中国家，引发了健康问题。在缺乏卫生设施的情况下，食品中心的工作人员可能会传播寄生虫感染。这是一项描述性研究，旨在确定2014年大不里士市食品从业人员肠道寄生虫感染的患病率。数据记录于健康中心办公室，所有被转介到实验室进行人口统计学和粪便检测以领取健康卡的食品处理人员的数据都在其中。在4612份样本中，有172例（3.73%）检测到寄生虫感染。总共156份阳性样本（90.69%）与原生动物有关，16份（9.3%）与蠕虫有关。大多数寄生虫感染与贾第虫和结肠内阿米巴有关，感染率最低的是微小膜壳绦虫。此外，教育程度与寄生虫感染率之间存在显著关系（P = 0.0044）。但感染类型与肠道寄生虫数量之间没有显著差异。结果表明，肠道寄生虫，尤其是致病性原生动物，在一些食品处理人员中很常见。因此，需要加强卫生控制，提高教育水平将对改善这些人的健康起到关键作用。
