The majority of cases occurred in the first half of the year （71.43%）， with the highest incidence in March. Male cases are more common （64.28%）. The population aged 40-59 has higher incidence rate （64.28%）. Farmers， retirees and unemployed individuals are more common in the cases （57.14%）. The main transmission route is direct contact transmission caused by cutting raw lamb meat （non slaughter workers） （57.14%）. The source of infection involves both within and outside Guancheng district， mainly within the district （50.00%）. There was no significant difference in incidence rate between Hui and Han nationalities （P>0.05）.Conclusion： Cutting raw mutton is the main risk factor of brucellosis in this district， which can be prevented by wearing gloves. The low occurrence of brucellosis in this district is related to the prohibition of raising livestock and private slaughtering. It is necessary to increase the publicity of brucellosis， further improve the food safety supervision and animal epidemic prevention and control system， and reduce the occurrence of brucellosis.
