Abstract

Parasitic diseases are the most widespread diseases in the world. They are transmited via contaminated water or food. Considering that the daily consumption of vegetables is estimated at 142g per person, the purpose of this study was to evaluate the occurrence of parasites in salads available for consumption in restaurants in Aparecida de Goiânia, Goiás State. Salad samples were collected from the restaurants and parasitological analysis was performed using the Willis, Hoffman, Faust and Ziehl Neelsen techniques as well as cultures for the isolation of free-living amoebae. 51 samples were analyzed, 16 (31.4%) were positive. The parasites detected were: Acanthamoeba spp. in 12 (23.5%); free-living larvae, Schistosoma mansoni and Entamoeba coli in 1 (2.0%); Endolimax nana in 2 (3.9%). The PCR technique determined that 17.6% of the samples presented Toxoplasma gondii DNA. These techniques evidenced that the salad samples presented parasite contamination not only in the restaurants with the lowest price per Kg, but also in the most expensive ones. Therefore, in addition to effective sanitary surveillance, prophylactic measures are necessary regarding suppliers, handlers and restaurant owners to prevent the spread of these and other parasites.

巴西阿帕雷西达戈伊尼亚Goiás市餐馆沙拉中寄生虫的发生情况
寄生虫病是世界上传播最广的疾病。它们通过受污染的水或食物传播。考虑到人均每日蔬菜消费量估计为142克,本研究的目的是评估Goiás州aprecida de goinia餐馆供应的沙拉中寄生虫的发生率。从餐馆收集沙拉样本,并使用Willis, Hoffman, Faust和Ziehl Neelsen技术进行寄生虫学分析,以及培养分离自由生活的变形虫。检出51份样本,阳性16份(31.4%)。检出的寄生虫有:棘阿米巴12只(23.5%);自由生活幼虫,曼氏血吸虫和大肠内阿米巴1只(2.0%);2例(3.9%);PCR检测结果显示,17.6%的样本含有刚地弓形虫DNA。这些技术证明,不仅在每公斤价格最低的餐馆,而且在最贵的餐馆,沙拉样品中也存在寄生虫污染。因此,除了有效的卫生监测外,供应商、处理者和餐馆老板也必须采取预防措施,以防止这些寄生虫和其他寄生虫的传播。
