这个问题提的好!
food safety：通常是指食品质的安全,也就是现在“食品安全”的概念,但更强调的是针对一些偶然的、食品意外污染的危害.
food security：通常是指食品量的安全,即是否有能力得到或者提供足够的食物或者食品.security在餐馆业是指保护消费者和雇员不受暴虐和犯罪危害.
FAO对food security的定义：指所有人在任何时候都能在物质上和经济上获得足够、安全和富有营养的食物以满足其健康而积极生活的膳食需要（世界食品首脑会议行动计划第一段）.这涉及四个条件：（1）充足的粮食供应或可获得量；（2）不因季节或年份而产生波动或不足的稳定供应；（3）具有可获得的并负担得起的粮食；（4）优质安全的食物.
Food Safety”与“Food Security”所针对食品的安全性是密切相关的,但所针对的引起食品安全问题的原因是各有侧重的.
Food security refers to the availability of food and one's access to it.A household is considered food secure when its occupants do not live in hunger or fear of starvation.参考资料：
Food security exists when all people,at all times,have access to sufficient,safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life.(FAO)
Food security for a household means access by all members at all times to enough food for an active,healthy life.Food security includes at a minimum (1) the ready availability of nutritionally adequate and safe foods,and (2) an assured ability to acquire acceptable foods in socially acceptable ways (that is,without resorting to emergency food supplies,scavenging,stealing,or other coping strategies).(USDA)[16][本帖最后由 zippo 于 2008-8-20 08:54 编辑]zippo at 2008-8-20 08:52:40
