Recently, the problem of food safety has received increasing concern all over the country. In the portrayal presented to us, a large number of people are staring at all kinds of food safety problems, for instance, melamine in baby formula, Sudan Red in KFC, poisonous color, cancer-causing chemicals, and so on. To sum up, food safety is facing unprecedented great challenges.

　　Food safety refers to that food shall be non-toxic and harmless, conforms to proper nutritive requirements and causes no harm to human health. It is a complex issue owing to a good many fundamental causes: the first and most crucial factor is that a large number of industrial raw materials are directly used in food production. Taking Sanlu powdered milk for instance, the producers use industrial material melamine to improve protein content in baby formula, which finally leads to infant’s kidney stone. Besides, other causes are the use of harmful chemical pesticides, the use of cheap harmful materials instead of harmless materials in food production, and so on.

　　With due consideration of the above argument, it is imperative to ensure food safety. First and foremost, the food safety management system should be perfected and utmost significance has to be attached by the authorities to food safety problem. What is more, in the long run, healthy food or green food industry should be vigorously advocated in a bid to ensure food safety, and then to ensure people’s health.

　　当今，食品安全问题在全国范围内引起越来越多的关注。图片中展示给我们，很多人们正在仰望着各种各样的食品安全问题，例如，婴儿配方奶粉中的三聚氰胺，肯德基食品中的苏丹红，色素，致癌物质等等。总之，食品安全正面临着前所未有的巨大挑战。

　　食品安全指食品无毒、无害，符合应有的营养要求，对人体健康不造成任何危害。这是一个错综复杂的问题，原因是多方面的：首先最重要的因素是许多工业原材料被直接用于食品生产。以三鹿婴儿奶粉为例，生产厂家使用工业原料三聚氰胺来提高婴儿配方奶粉中的蛋白质含量，最终导致婴儿患肾结石。此外还存在其他因素，像使用有害化学杀虫剂，在食品生产过程中使用价格低廉的有害原料代替无毒害的原料，等等。

　　有鉴于此，确保食品安全至关重要。食品安全管理体系需要被完善;政府应该更加关注食品安全问题。此外，从长远来看，我们应该大力提倡健康食品或是绿色食品产业以确保食品安全，进而保障人民健康。
