安全是指无物质危险和无精神恐慌,使其处于自由的状态和措施。一方面是指安全的状态,即免于危险,没有恐惧;另一方面是指对安全的维护,指安全措施和安全机构[1]。从本质上讲,安全就是预知人们活动的各个领域存在的固有危险和潜在危险,并为消除这些危险的存在和状态而采取的方法、手段和行为。安全包含很多方面,有生命安全(毒品、疾病预防、灾难预防)、交通安全(出行环境),生产安全(煤矿及矿山安全、危化品、烟花爆竹安全)、国防安全,网络安全(信息安全)、环境安全(环境污染)、公共安全(公众聚集场所安全)和食品安全等。目前,食品安全的理念已贯穿到经济社会的各个领域中。国以民为本,民以食为天,食以安为先。食物是人类赖以生存和发展的物质基础,也是国家安定、社会发展的根本要求,在任何一个国家,保证食品安全是最基本的安全。
食品安全的危害主要来自三个方面:物理危害、化学危害和生物危害[2]。安全危害源不仅存在于食品的原料、加工、贮藏、流通等环节,更重要的来源之一是环境污染。近年来,水污染问题时有发生,生活饮用水的安全受到严重危害。引用水的安全问题,不仅关系到个人的生命和健康,而且,关系到国家和政府形象,关系到社会的稳定和发展。
