Abstract: Objective To understand the situation of seroepidemiology of Toxoplasma gondii infection among employees in a pork food processing enterprise in Dongtai City. Methods Totally 200 employees from a pork food processing enterprise in Dongtai City were selected as the research objects. The venous blood of the selected population was extracted and the IgG antibody against T. gondii in serum was detected by ELISA， and the results were analyzed. Results Among the 200 employees， 36 cases were positive in IgG antibody detection， the positive rate was 18.0%. The positive rate of IgG antibody among workers with different length of service was significantly different （[χ2] = 9.813， P ＜ 0.05）. With the increase of working age， the positive rate of IgG antibody gradually increased. The positive rate of IgG antibody to T. gondii was significantly higher in the population who had frequent contact with animals. Conclusions The positive rate of IgG antibody against T. gondii in employees in pork food processing enterprises is high. Therefore， the detection of antibodies against T. gondii and health education should be strengthened in this population.

摘要： 目的 了解东台市猪肉食品加工企业从业人员弓形虫感染情况。方法 以东台市某肉食品加工企业从业人员200例作为调查对象，采集其静脉血并分离血清，采用酶联免疫吸附法检测血清抗弓形虫IgG抗体。 结果 200例肉食品加工企业从业人员中，血清抗弓形虫IgG抗体阳性36例，阳性率为18.0%。不同工龄者血清抗弓形虫IgG抗体阳性率差异有统计学意义（[χ2] = 9.813，P ＜0.05）；随着工龄的增加，血清抗弓形虫IgG抗体阳性率逐渐升高。与动物直接接触频繁者血清抗弓形虫IgG抗体阳性率明显升高。结论 东台市猪肉食品加工从业人员血清抗弓形虫IgG抗体阳性率较高，对此类人群应加强弓形虫感染检测及健康教育。
