生产线上安装的金属探测器可保护消费者免受物理损坏，以及制造商免受图像损害的影响，因此，经济损害。他们帮助食品加工行业确保产品质量，但所有其他预防措施避免了外国身体的存在 - 如准确维护生产设备，选择进入材料和供应商和连续人才培训 - 不应被忽视。
食品安全是一个必备的食品行业无法生产的先决条件。When thinking of food safety, the fi rst things that ring a bell in one’s mind are microbiological hazard (pathogenic contamination) and chemical hazard (contamination through toxic chemicals such as phytopharmaceuticals, mycotoxins, material that migrates from the package to the foodstuff, etc.), but there is another important aspect that is often underestimated: the physical hazards, that’s to say the presence of foreign bodies of different kind. H.A.C.C.P. criteria are mainly oriented towards the prevention of microbiological hazards, but their observance in compliance to Art. 5 of the EC Regulation 852/2004 involves that “a food business operator shall identify and prevent risks”, hence all kinds of risks must be taken into account. Next to the self-control handbook, there are voluntary certifi cations such as UNI EN ISO 9001, which outline the requirements for Quality Management Systems that enhance customer satisfaction, for expanding the company vision to all production processes, for delivering products of standard quality complying with the set requirements, the importance of constantly improving performances, know-how and process control, the capacity of involving the human resources in the prevention of all kinds of hazards and risks. There are many other voluntary certifi cations, which become essential when the products are directed to retailers. In fact, many supermarket chains that sell many products with their own label, are very demanding when protecting the confi dence customers have in their trademark.
这几乎总是转向欧洲IFS（国际食品标准）和BRC（全球食品安全DEL英国零售财团的全球标准）CERTIFI阳离子的要求。IFS标准的范围是加强零售链中品牌食品供应商的选择，以提供安全产品的能力，遵守合同规范，显然是食品安全标准和现有法律。IFS标准在欧洲和全球范围内被接受，以及GFSI（全球食品安全倡议），这是一项关于食品安全计划要求的国际倡议，以提高整个食品供应链的成本效率。最近，GFSI宣布，几家国际零售商已经普遍接受四个GFSI基准食品安全计划，使其共同标准定义，其目的是使食品制造尽可能安全，同时减少审计重复。IFS标准规定请求使用金属探测器。BRC是另一个GFSI接受ED标准，是在1998年开发的，主要是为了确保所有品牌产品都根据良好的DECI NED质量标准生产，以满足最低要求。它可以与标准将零售商联系到零售商的标准。BRC Certifi阳离子是必须出口到欧洲国家的必备，并且是公司可靠性的既定保证。非欧洲市场，例如美国市场，几乎表现出疯狂的注意力对整个异物的缺失，李多提高于致力于残留兽药存在的注意力。打算在这些市场上推销产品的公司必须特别注意身体危害。
