摘　　要：目的研究出口分割鸡肉中大肠杆菌O157∶H7的控制措施。方法建立了出口分割鸡肉中大肠杆菌O157:H7在速冻过程中的失活模型和在-18℃下的存活模型,通过风险分析提出控制措施。结果利用所建模型定量描述了出口分割鸡肉从成品到消费过程中大肠杆菌O157∶H7带菌量的变化,得出摄入1份鸡肉感染大肠杆菌O157:H7病的风险。结论本研究提出的控制措施可提高出口分割鸡肉的安全性。Objective Study the control measures of Escherichia coli O157 ： H7 in the exported divided chicken. Methods The deactivation model in deepfreeze and survival model at -18℃ of Escherichia coli O157 ： H7 in the exported divided chicken were established to obtain the control measures by risk analysis. Results The quantitative change of Escherichia coli O157： H7 from product to consumption was quantitatively described by using the above models and the risk of eating one portion of chicken that caused disease of Escherichia coli O157： H7 was evaluated. Conclusion The control measures mentioned in this study can increase the safety of the exported divided chicken.
