In order to verify the presence of intestinal parasites in food handlers, stool samples were collected from 104 cooks and their helpers that were working in food preparation in 20 public elementary schools, in various areas of the city of Uberlândia, Minas Gerais, Brazil. The samples were collected during the months of November and December, 1988, in plastic flasks containing a 10% formaldehyde solution and processed by the Hoffmann, Pons & Janer method. The sediment was examined using triplicate slides. All individuals were females aged between 24 to 69 years. Intestinal parasites were found in 85.0% of the studied schools and 47.1% of the studied food handlers (cooks and helpers) were found to be positive. Among the 49 infected food handlers, 32 (65.3%) carried a single parasite and 17 (34.7%) carried two parasites. The following intestinal parasites were found: Giardia lamblia (21.1%), Entamoeba coli (21.1%), hookworms (9.6%), Ascaris lumbricoides (5.8%), Entamoeba histolytica (2.9%), Hymenolepis nana (1.9%), Strongyloides stercoralis (1.0%). These data emphasize the need for a rigid semi-annual control in all school food handlers, including diagnosis, specific treatment and orientation about the mechanisms of transmission of the intestinal parasites.
为了核实食品从业人员肠道寄生虫的感染情况，从巴西米纳斯吉拉斯州乌贝兰迪亚市不同区域20所公立小学从事食品制备工作的104名厨师及其助手那里采集了粪便样本。样本于1988年11月和12月采集，置于装有10%甲醛溶液的塑料瓶中，并采用霍夫曼、庞斯和贾内尔方法进行处理。使用三张载玻片对沉淀物进行检查。所有个体均为年龄在24至69岁之间的女性。在所研究的学校中，85.0%发现有肠道寄生虫，在所研究的食品从业人员（厨师和助手）中，47.1%被检测出呈阳性。在49名受感染的食品从业人员中，32人（65.3%）携带单一寄生虫，17人（34.7%）携带两种寄生虫。发现的肠道寄生虫如下：蓝氏贾第鞭毛虫（21.1%）、结肠内阿米巴（21.1%）、钩虫（9.6%）、蛔虫（5.8%）、溶组织内阿米巴（2.9%）、微小膜壳绦虫（1.9%）、粪类圆线虫（1.0%）。这些数据强调了对所有学校食品从业人员进行严格半年一次检查的必要性，包括诊断、特异性治疗以及关于肠道寄生虫传播机制的指导。
