Objective To understand the current situation of soil-borne nematode infection in Dalian and to provide a scientific basis for prevention and control of soil-borne nematodes. Methods A random sampling method was used to select the survey sites to collect the feces of the residents. The soil samples of soil-borne nematode were examined by the modified Kato thick smear method (the second feces test) and the feces of children under the age of 12 egg. Results A total of 6 009 people were surveyed. Twenty-five soil man-made eggs were found in the faeces, with an infection rate of 0.42%, including roundworm eggs, whipworm eggs and two mixed infections. Conclusion The infection rate of soil-borne nematodes in Dalian is obviously lower. Health education should be strengthened and manure management should be strengthened to eliminate soil-borne nematode infection completely.
