GĐXH - Going to the doctor because of symptoms of bloating, nausea, and abdominal pain, a 36-year-old girl was unexpectedly diagnosed with stomach cancer.
Recently, Ms. Chang (36 years old in China) often felt uncomfortable with symptoms such as bloating, nausea, and abdominal pain. At first, she thought it was a stomach disease, so she bought stomach medicine to take.
However, her condition did not improve but became worse, so she went to the hospital. After running all the tests, the doctor confirmed that she had stomach cancer.

In the medical history, Chang said that because of her busy work schedule and living alone, she only bought food once a week and stored it in the refrigerator to eat gradually. She had a habit of cooking for many days at a time and often did not throw away food.
Dr. Gao Jiankai, Deputy Head of the Emergency Department of Zhengzhou People's Hospital (China), said that although the temperature of the refrigerator is low, it actually has no sterilization effect. Common bacteria that can still grow in the refrigerator environment include Salmonella, Shigella, Yersinia and Listeria, which can be harmful to human health after entering the body, and can even lead to complications such as sepsis, and even mold containing aflatoxin - a strong carcinogen.
Why you should not eat food stored in the refrigerator regularly
Vegetables and meat are cooked foods that often contain a certain amount of nitrate. Especially green vegetables such as spinach, cabbage, asparagus... When stored in the refrigerator for many days, nitrate will be converted into nitrite under the influence of bacterial enzymes and the amount of nitrite will gradually increase over time. After being eaten, nitrite will affect the stomach and produce carcinogens.
In addition, in the closed space of the refrigerator, many bacteria grow faster, food left overnight in the refrigerator not only does not retain its freshness but also becomes contaminated, easily producing carcinogens even when boiled again. Among them, seafood is the most dangerous food, seafood stored overnight will produce bacteria, denature proteins, cause food poisoning, and be dangerous to the liver and kidneys.

How long does cooked food last in the refrigerator?
Cooked fish and seafood should be used within 2 days of being refrigerated. In the case of frozen whitefish, it should be used within 3 months.
Meat prepared in stews, broths or sauces can be consumed within 2 days of storage. When frozen, the storage time can be extended to 4 months. Storage time is determined not only by good refrigeration and airtightness, but also by the fat content of the food. The higher the fat content, the faster the food will spoil.
Cooked poultry can be stored in the refrigerator for up to 4 days. If frozen, you can store it for up to 1 year.
Soup can be stored in the refrigerator for up to 4 days. If frozen, it can be stored for up to 3 months.
Pasta and rice both keep their flavor for 4 days if stored in the refrigerator. If frozen, they can be used within a month.
Prevent cancer when using refrigerator
- Keep the refrigerator clean : Clean the refrigerator regularly, at least once a month. Every time you take out food, you must wipe away residue and waste water.
- Food classification : For example, it is best to store vegetables, fruits and meat separately to avoid the risk of cross-contamination.
- Don't wait for food to cool before putting it in the refrigerator : If you want to save leftovers, put warm dishes directly into the refrigerator to reduce the possibility of bacteria breeding. After taking out leftovers, reheat them before eating.
