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.

當今，食品安全問題在全國范圍內引起越來越多的關注。圖片中展示給我們，很多人們正在仰望著各種各樣的食品安全問題，例如，嬰兒配方奶粉中的三聚氰胺，肯德基食品中的蘇丹紅，色素，致癌物質等等。總之，食品安全正面臨著前所未有的巨大挑戰。

食品安全指食品無毒、無害，符合應有的營養要求，對人體健康不造成任何危害。這是一個錯綜復雜的問題，原因是多方面的：首先最重要的因素是許多工業原材料被直接用于食品生產。以三鹿嬰兒奶粉為例，生產廠家使用工業原料三聚氰胺來提高嬰兒配方奶粉中的蛋白質含量，最終導致嬰兒患腎結石。此外還存在其他因素，像使用有害化學殺蟲劑，在食品生產過程中使用價格低廉的有害原料代替無毒害的原料，等等。

有鑒于此，確保食品安全至關重要。食品安全管理體系需要被完善;政府應該更加關注食品安全問題。此外，從長遠來看，我們應該大力提倡健康食品或是綠色食品產業以確保食品安全，進而保障人民健康。
