April 7 is the “World Health Day” and this year’s theme is “from farm to table, and everybody is responsible for food safety”. WHO emphasizes that farmers, retailers, cooks and consumers should take up their responsibility and launch “five essentials for food safety” guidelines.
   

The “five essentials” of the guidelines are to keep clean, separate raw and cooked food, ensure the food is cooked, keep food temperature and use safe water and raw materials. WHO has also suggested that the root of vegetables and fruits shall be thoroughly peeled off and leaf vegetables and fruit shall be immersed with safe water.
   

WHO pointed out that unsafe food containing harmful bacteria, viruses, parasites or chemical will cause diarrhea, cancer and more than 200 kinds of diseases. According to statistics, food-borne and waterborne diarrhoeal diseases will lead to death of about 2 million people every year, and many of them are children.
