摘　　要：Escherichia coli(E.coli)that produce Shiga toxin or verocytotoxin is commonly known as Shiga toxinproducing E.coli(STEC)or verocytotoxin-producing E.coli(VTEC).Hemorrhagic enteritis(HC),caused by foodborne zoonotic pathogen enterohemorrhagic E.coli(EHEC)O157:H7,was first reported in the United States in 1982 and has since caused outbreaks of human infections in various countries such as Canada,Japan,and China.In China,the pathogen was isolated from the feces of patients with diarrhea in Xuzhou City,Jiangsu Province in 1986.It later caused an outbreak in Xuzhou and adjacent areas from 1999 to 2000(1).Measures that included investigation of diarrhea patients,identification of the pathogen,and clearing epidemiological characteristics were implemented to control the spread of the disease.Subsequently,a surveillance program was reformulated in 2001 in Tongshan District,Xuzhou City based on the national O157:H7 surveillance program and the reality of Jiangsu Province.The program included 18 towns for diarrhea patients and food surveillance,and 3 major animal farming towns for animal surveillance.The program has led to changes in the detection rates and virulence genes of the strains.In this study,we analyzed O157:H7 surveillance data from 2001 to 2021 to predict possible transmission risks.
