The dangers of eating expired food, the hazards of expired food

Yes. Expired food is infected by Salmonella, Vibriobacteria, Escherichia coli and other bacteria, causing nausea, vomiting, diarrhea and even sudden diseases such as respiratory and circulatory failure; In addition, expired food may also undergo chemical changes when infected by bacteria, producing aflatoxin, nitrosamines, acrylamide and other substances, resulting in chemical poisoning, inducing cancer, cardiovascular diseases and even genetic mutations.

The deterioration of food is a continuous gradual process. Food ingredients, or the bacteria in them, don't watch the expiration date change according to our instructions – it doesn't do what many people think: stay honest until the expiration date; After the expiration date, it suddenly becomes poison.

This change process is affected by the production process and storage conditions. For example, pasteurized milk will not exceed the standard of bacteria after two weeks of refrigeration; In the case of UHT sterilization, bacteria will not grow for several months or even years at room temperature. Even for the same food, such as pasteurized milk, the process control conditions of different manufacturers can cause the process to change at different speeds.

It should be noted that "no deterioration within the shelf life" needs to follow the manufacturer's storage requirements to achieve. Otherwise, the food may also spoil during the shelf life.

Dairy: Fresh dairy products usually have a shelf life of 7 days when refrigerated, and if exposed to room temperature, they can spoil within a few hours.

Milk powder food: 24 months for tinplate canned sealed nitrogen-filled packaging, 12 months for non-nitrogen-filled packaging, 9 months for glass bottles, and 6 months for plastic bags.

Edible oil: The usual shelf life is 18 months, which is provided that the packaging is unopened. The shelf life of edible oil will be shortened accordingly after opening, and it is best to consume it within 3 months.

Rice noodles: The shelf life of rice noodles at room temperature is 6 to 12 months. If it is in the north, as long as it is not placed in a hot and humid place, the storage conditions are also normal, and it can be extended to 24 months. However, once the rice noodles become moldy, they should never be eaten.

Alcohol: 11 degrees and 12 degrees for provincial high-grade cooked beer for 4 months, ordinary cooked beer for 2 months; degree of cooked beer for 50 days; 6 months for fruit wine; 3 months for sparkling wine.

Bread and pastry: generally 7 days in winter, 3 to 5 days in spring, 1 to 2 days in summer. Because it contains moisture, if it is not stored properly, bread and pastries may become moldy the next day, and once moldy, they must be discarded.

Eggs: There is no fixed shelf life, 3 to 5 weeks are generally no problem, but every week that passes, the quality of eggs will drop by a grade, and they must be used as soon as possible.

The hazards of consuming expired food include the following. First of all, it is easy to cause digestive diseases, some expired foods will breed a large number of bacteria due to spoilage, and the human body will cause bacterial infection of the digestive system after consumption, causing diseases, common diseases include acute gastroenteritis, bacterial dysentery, Helicobacter pylori infection, etc. Secondly, it can increase the risk of cancer, for peanuts, cakes, rice and other expired foods after a series of chemical reactions, it is easy to produce carcinogens such as aflatoxin and nitrite compounds, after these harmful substances enter the human body, not only will cause different degrees of damage to the liver system, and even lead to malignant tumor diseases in local tissues of the human body.

Therefore, in the daily diet, it is necessary to pay more attention to the specific expiration date of the food and avoid eating expired food.

Eating expired food can lead to impaired gastrointestinal function and gastroenteritis, which is mainly manifested as abdominal pain, bloating, diarrhea, nausea, vomiting, fever, loss of appetite and other symptoms. When you usually buy food, you must pay more attention to the production date and never buy expired food. If you accidentally eat expired food and cause clinical symptoms, you can take some norfloxacin, enteritaning, and smecta orally**.

If the situation is serious, go to the hospital in time**.

Eating expired and spoiled food will definitely cause harm to the human body, but if the intaker's resistance is strong, he can slowly dissolve the toxin, and if the resistance is weak, he may suffer from acute gastroenteritis, toxemia and other diseases.

It is indeed harmful, in fact, some of the production dates of food are advanced, that is, the production today may be the next month's order, and the date is printed as the future date.

How many months are referring to.

If there is only one month or less left in the date, then eat with caution.

Manufacturers always advance the production date by a long time.

Eating expired food can lead to poisoning, dizziness, headache, nausea, vomiting, diarrhea and other poisoning symptoms, and may also lead to kidney failure, heart failure and other symptoms, and in severe cases, it will be life-threatening.

What are the effects of eating expired food? 3 types of expired foods that we need to know about are commonly eaten.

1. The shelf life is not equal to the last edible time, after the shelf life, some foods are still edible from the perspective of safety, but its quality may decline to some extent. For example, after the frozen food expires, the pathogenic bacteria may not exceed the standard, and there is no adverse reaction after cooking, but due to the storage time for too long, the flavor and texture have undergone some changes, the taste is not fresh, the vitamin content has also decreased, and the fat may be slightly oxidized.

2. Eating nucumberic orange poisoning is divided into two categories: biological type and chemical type. Biological poisoning refers to the infection of expired food with Salmonella, Vibriobacteria, Escherichia coli and other bacteria, causing nausea, vomiting, diarrhea and even respiratory and circulatory failure.

In addition, expired food may also undergo chemical changes when infected by bacteria, producing aflatoxin, nitrosamines, acrylamide and other substances, resulting in chemical poisoning, inducing cancer, cardiovascular diseases and even genetic mutations.

3. Food that has passed the expiration date does not necessarily mean that it can no longer be eaten, which is like a machine that has passed the expiration date, although it can also be used, but the risk increases. However, you should not eat expired food, because even within the expiration date of food may shorten the shelf life due to the opening of the packaging or improper storage, so you should pay special attention.

4. In order to extend the shelf life of the product and prevent it from sensory changes, manufacturers may add some chemical raw materials, such as preservatives. Eating it can cause chronic poisoning, especially to children and pregnant women.
