If the meat is frozen for too long, if the moisture is lost too much, the meat will dry out, and the meat will taste and nutriently poor, and if the situation is severe, it will be like sawdust and lose its edible value. Long-term use of frozen meat can lead to food poisoning and even nutrient deficiencies, which will continue to reduce immunity and resistance, endangering one's own safety: basically, frozen meat will not spoil, if stored for a long time, it will cause some changes in temperature, once the refrigerator door is opened and closed, it will lead to the continuous multiplication of bacteria and viruses in the meat, in addition, if the freezing environment is not particularly good, it will lead to the long-term reproduction of parasitic insects in the meat and the continuous decline of meat quality.
Long-term use of this frozen meat can cause bacterial and parasitic infections in the body, destroy nutrients, continuously reduce immunity, fail to fight viruses and bacteria, and adversely affect physical health. In China, the recommended shelf life for frozen meat is usually 1 year, red meat, including pork, lamb and beef, generally has a shelf life of 10 to 12 months, and poultry has a slightly shorter shelf life than red meat, about 8 to 10 months, compared to chicken, duck and goose.

It is indeed carcinogenic, and the meat in the refrigerator can generally not be eaten after a month, and even if it is placed in the freezer, the meat has already deteriorated.
-
Pork that has been frozen for a year is not carcinogenic and can be eaten.
Frozen meat in an ideal state, that is, fresh and pollution-free meat is quickly frozen below minus 25, stored at a constant temperature of minus 18, pork, beef and mutton and other livestock meat shelf life can reach 2 years, chicken, duck and other poultry meat properties are not as stable as animal meat, shelf life can reach 1 year.
Although frozen meat has a long theoretical shelf life, meat purchased from supermarkets is susceptible to bacterial contamination during the sales process, and it is difficult to guarantee the freshness of the raw materials.
In addition, the door of the household refrigerator is often opened and closed, and the sudden power failure will cause the temperature of the refrigerator to fluctuate, and the change of temperature will accelerate the oxidation and decomposition of nutrients such as fat, protein, and vitamins, and bacteria will also grow slowly, resulting in the reduction of the nutritional value of meat, the deterioration of taste and flavor, and the oxidation intermediate products that accelerate human aging.

Many people have the habit of buying many people at one time, storing them in the refrigerator, and eating them as they go. In fact, this practice is completely undesirable, the meat is frozen for too long not only affects the taste of the meat, but also has no nutritional value, long-term eating of frozen meat for a long time will also have a great impact on the body, accelerate aging, diarrhea, increase the chance of cancer, etc. So what's the harm of meat that's frozen for a year?
Space has been frozen for a year of meat hazards.
1. Accelerate aging.
The low temperature of the freezer can prevent the proliferation of bacteria, but it cannot completely prevent the oxidation of fat and protein, and therefore the deterioration of meat quality.
Due to the oxidation reaction, the color of the frozen lean meat will gradually change from red to brown, and the fat meat will gradually turn yellow, which will not only deteriorate the flavor, but also produce fat oxidation products that accelerate human aging.
2. Increase the risk of cancer.
Expired frozen meat contains a lot of bacteria, and even some subtle parasites will be in it, which are harmful to the body, long-term consumption of expired frozen pork will lead to a decrease in people's own immunity, and even increase the chance of cancer.

3. Easy diarrhea.
According to the "Strait Herald", Aunt Lu in Xiamen made a special table of dishes in order to entertain her son's girlfriend who brought home for the first time. When I arrived at the hospital, the doctor diagnosed that Aunt Lu's family suffered from gastrointestinal diseases because of eating frozen and spoiled food, and the culprit was the frozen meat in the refrigerator.
According to clinical statistics, the number of patients with inflammatory bowel disease is increasing year by year, and about 30% of them report that they have stored food in the refrigerator for too long.
Space has been frozen for a year of meat hazards.
4. Large loss of vitamins.
Frozen meat not only tastes bad, but also breaks down essential amino acids if the protein is oxidized. The longer you freeze, the greater the loss of vitamins, especially B vitamins.
5.Do not thaw and then freeze.
When defrosting meat, it is best to take it out of the freezer layer of the refrigerator in advance, put it in the refrigerator overnight, and naturally refrigerate and thaw it, with the least loss of flavor and gravy, but avoid secondary freezing after thawing. If you freeze and thaw repeatedly, the bacteria will multiply even more frantically.

We need to eat as fresh meat as possible, but we also need to avoid eating meat that has been frozen for too long.
At the same time, if a person eats frozen meat for a long time, because this way is indeed unhealthy, and may even increase the risk of cancer in a person, we need to avoid this wrong lifestyle as much as possible, and we need to pay more attention to the health and freshness of our ingredients. If a food is repeatedly frozen, the inside of the food may contain various bacteria and parasites, and there will also be a certain risk of carcinogenesis. <>
It is best not to freeze meat for more than two days.
In most cases, fresh meat does not have much off-flavor, and at the same time, it will have a bright red color, and the texture will be tighter, and there will be no damage. If the meat is frozen for too long, this method will not only destroy the nutrients in the meat, but also may cause a lot of bacteria and carcinogens to be produced in the meat, so we need to control the time of freezing meat to less than two days as much as possible. <>
Frozen meat for too long may produce some carcinogens.
You can try to understand that almost all foods should not be refrigerated for too long, because this method itself is very easy to cause bacteria to multiply, and some bacteria themselves will produce a certain amount of carcinogenicity, if a person eats this food regularly, this may increase our risk of cancer. In modern society, we not only need to ensure the health and freshness of meat, but also need to ensure the freshness of all ingredients, which can make us healthier, so we need to pay close attention to the freshness of various foods. <>
Finally, if we use the refrigerator for a long time, we need to clean the fridge regularly and disinfect the refrigerator as much as possible. If we can do this, we can not only ensure that the food in the refrigerator will not carry over the flavor, but also ensure the health of the food in the refrigerator.

If the food is heated to 100 percent, bacteria are likely to multiply, so it is important to keep the temperature constant when heating.
PrecautionsMeat should be frozen for a long time, in a relatively low environment, can prolong the storage time, to avoid deterioration, if the meat is often frozen, it is likely to make the moisture in it swell, so that the inner wall of the cell is bad.
