浅析食品安全风险评估和农业标准化的关系

食品安全风险评估是近年来国际上出现的保证食品安全的一种新模式,农业标准化是提高农产品质量的技术保障,实施农业标准化是保障粮食和食品安全的必要手段。阐述了食品安全风险评估和农业标准化的基本情况,论述两者的关系,以HACCP体系为例剖析两者结合是未来食品安全管理体系的方向。     

HACCP体系在速冻猪肉生产流程中的应用

危害分析与关键控制点(HACCP)是国际上认可和接受的食品安全保证体系,主要是对食品中生物、化学和物理危害进行安全控制。运用HACCP管理体系的基本原理分析速冻猪肉加工工艺中潜在的危害及控制措施,确定关键控制点,建立HACCP质量管理体系,可以将速冻猪肉产品可能出现的危害降至最低程度,确保速冻猪肉的生产安全。     

Presence and Numbers of Campylobacter,Escherichia coli,and Salmonella Determined in Broiler Carcass Rinses from United States Processing Plants in the Hazard Analysis and Critical Control Point-Based Inspection Models Project

In 1999, the USDA-Food Safety and Inspection Service introduced an inspection system called the Hazard Analysis and Critical Control Point-Based Inspection Models Project (HIMP). The HIMP varies from standard inspection in that the emphasis of Food Safety and Inspection Service inspection program personnel is shifted. Each carcass is still visually inspected according to the Poultry Products Inspection Act, but some responsibility for food safety and identification and removal of defects is shifted from the regulatory agency to the processor, freeing up inspectors to more effectively verify the process and food safety system of the establishment. This survey was conducted in 2 stages: first to examine carcasses collected in HIMP and non-HIMP plants and then to test carcasses from all 20 volunteer plants currently operating under HIMP inspection. Carcasses were collected at rehang and postchill being careful to follow the same flock through processing. Postchill carcasses from HIMP plants were found to have equal bacterial contamination (numbers of Campylobacter and Escherichia coli and presence of Salmonella) as carcasses from standard HACCP plants. Overall, HIMP inspection, which places additional responsibility on the plant for process control, does not affect the microbiological quality of fully processed broiler carcasses.

氮磷钾肥对南板蓝穿孔病发生及防治的影响

运用试验设计及数理统计的方法探讨了氮磷钾肥对南板蓝穿孔病危害程度的影响及该病的防治措施。在南板蓝的栽培周期内,南板蓝穿孔病在7月12日前后的危害最重。在尿素、碳铵、硝铵3种肥料中,使用尿素时南板蓝穿孔病的发生率最低,危害程度最轻。氮、钾肥的施用量及氮、磷肥的合理配施对南板蓝穿孔病的防治具有重要作用。     

突泉县杨家街屯北沟泥石流基本特征及危险性评价

分析了内蒙古自治区突泉县杨家街屯北沟泥石流沟的地形地貌、物源、水源及动力学特征,采用刘希林推荐的单沟泥石流危险度评价法评价了该泥石流沟的危险性,并提出了防治建议。结果表明,该泥石流沟的形成条件充分,属中度危险泥石流沟,建议在沟口两岸修筑导流堤工程。
