Food safety is a problem in all places around the world and people in different areas of the world prepare foods in different ways. The WHO released (发布) five simple rules for preparing food in a safe way. They call these rules the “Five Keys to Safer Food”.
Key 1: Keep clean
1.. People should wash their hands often — before touching food and while they are preparing food. People should wash all surfaces and equipment used for preparing food.
Key 2: Separate raw (生的) and cooked
Raw foods should not touch prepared foods. 2..
Key 3: 3.
People should cook eggs and meat especially carefully. These foods may carry more micro-organisms (微生物) than other foods. Food like soup must be boiled for at least a minute to make it be cooked completely. It is also important that people re-heat cooked food completely.
Key 4: Keep food at safe temperatures
When people finish eating, they should keep the left food in a refrigerator below 5℃and shouldn’t store it for too long. At room temperature, about 20℃, the amount of micro-organisms can increase very quickly. But temperatures above 60℃ or below 5℃ control the growth of micro-organisms. 4..
Key 5: Use safe water and raw materials
