[Seroepidemiological survey of Toxoplasma gondii infection among employees in a pork food processing enterprise].

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.
