What are "raw food" and "cooked food"?

Raw food refers to raw materials for making food, such as fish, meat, eggs, poultry, vegetables, grains, etc. Cooked food refers to food that can be directly consumed by humans, such as cooked meat, ham, roast chicken, assorted vegetables, etc. Raw food often contains many bacteria and parasite eggs. There are basically no bacteria and parasite eggs in cooked food after processing. However, if you do not pay attention to separating them during processing and storage, for example:

Use a knife that has been used to cut raw food to cut cooked food; use a container that has been used to hold raw food without washing and sterilizing it to hold cooked food. Food, etc., will contaminate the bacteria and parasite eggs on the raw food to the cooked food again, and multiply in the cooked food, endangering human health. Therefore, raw and cooked foods should be placed separately.

1. Raw and cooked food should be separated into kitchen knives and chopping boards that are in direct contact with the food. When cutting raw food, bacteria in the food will remain on them, and there are more bacteria and parasite eggs on the lettuce. . If it is later used to cut cooked food, bacteria will directly contaminate the cooked food through kitchen knives and chopping boards. Even if you scald it with boiling water to "disinfect" it before use, the bacteria are often not completely eliminated. Therefore, to ensure food safety, you should prepare two kitchen knives and two cutting boards at home and use them separately. Moreover, it is safer to boil cooked food in boiling water before cutting it.

2. Keep the cutting board clean. After using the cutting board, scrub it with a hard brush and clean water to remove the dirt along with the sawdust. If there is a fishy or meaty smell left, wash it with rice water or detergent dissolved in salt, and then wash it off with warm water. Do not blanch it in boiling water, because the protein in the meat will remain on the cutting board and will solidify when exposed to heat, making it difficult to clean. After washing, stand up to dry. After the cutting board has been used for a period of time, you can use a kitchen knife to scrape the wood chips on the cutting board, or use a woodworking plane to plan it, so that the dirt on the cutting board can be completely removed, and the cutting board can be kept flat and easy to use.

3. The reason why raw and cooked food should be separated is because livestock, poultry and aquatic products directly contaminate cooked meat and cold dishes, or food is refrigerated without separating raw and cooked food, meat and vegetables, which is a common problem in restaurants, collective canteens and families. An important cause of food poisoning. Because raw food contains many disease-causing bacteria or parasite eggs. According to data reports, 30% of pigs, beef, and mutton are found to be pathogenic; 79% of fruits and vegetables are contaminated with intestinal bacteria such as Escherichia coli, and 81% are found to contain roundworm eggs. When processing these foods, bacteria or parasite eggs will inevitably contaminate the utensils. If these utensils are used to process and hold cooked foods,

then the bacteria and parasite eggs will contaminate the cooked foods. People may get food poisoning or parasitic diseases after eating it. Utensils for raw and cooked food, including kitchen knives, cutting boards, baskets and utensils, must be equipped with two sets and used separately for raw and cooked food.

Some families do not prepare two sets of food utensils, but after processing and serving raw food, the utensils should be washed or scalded with boiling water and disinfected before serving cooked food.
