Can deformed canned food should be discarded or eaten?

The box containing distorted processed foods is distorted, or the lid is inflated, reflecting the quality of the food contained in the box, which no longer ensures food safety and hygiene, which may be dangerous to the user's health.

The box is also distorted!

Many people choose ready-to-eat canned foods that can be used immediately for family meals, or on trips, because their convenience is instant, or just reheating through a microwave.

Most housewives said that if the box is slightly distorted, it is important that the quality of the food in the box.

Many people think that just need to care about the production date, but not expired but can also be a little canned.

Harmful health because poisonous bacteria invade

According to Mr. Luu Thi Le Thuy - Director of the Food Industry, Ho Chi Minh City, for ready-to-eat foods, packaging can play an important role in ensuring food hygiene and safety. The canned shell is distorted, or bulging due to the transport of impacted goods, this is a mechanical impact that sometimes makes the corners of the lid of the box open, the gap does not leak food water. in the box it is difficult to identify with the naked eye.

The box has openings, so the food inside will be affected. The box is not distorted but inflated on the lid or bulged on the bottom, then the cause of the bulge is because the process of making cans does not guarantee the process of cleaning the cans, does not guarantee safety immediately when canned. On the other hand, sometimes the cause of the quality of food in the box is not guaranteed, microorganisms decompose and produce toxic vapors causing swelling of the lid and box.

The type of bacteria that normally infects the canned food must include clostridium botulinum , which is often found in canned bacon, smoked canned fish . and cannot be sterilized at the right temperature and time. Eating this bacterium toxin goes straight to the blood and damages the nervous system. People who are poisoned will have dizziness, difficulty swallowing, and have difficulty breathing.

This type A toxin is one of the powerful toxins, which can lead to death in very small amounts. There are also some bacteria that cause diarrhea, vomiting, and food poisoning.

Associate Professor Ha Thuc Chi Nhan - Deputy Head of the Department of Materials Science, Ho Chi Minh City University of Natural Sciences, said that there are many types of materials used to make ready-made food containers. Plastic box if distorted, inflated when subjected to heat, then additive from easily decomposing box into toxic food . Box of tin material containing food, when left for a while, the bulging box is caused by The food in the box that has been invaded by microorganisms causes decomposition to form gas, release CO 2 , increase the pressure in the box, the box will expand and expand.

The box is bulging, or distorted, consumers need to think immediately about the food inside the box is broken.

With acidic food, the box surface must be coated with anticorrosion, if it is corroded, it will cause bulging, not at this time due to microbiological swelling but due to chemical swelling. The box is bulging, or distorted, consumers need to think immediately about the food inside the box is broken.

At the same point, MSc Nguyen Huu Quyen - Head of the Department of Food Technology, Ho Chi Minh City University of Food Industry said that canned foods are easily distorted and inflated, often because pasteurization is not guaranteed. The canned pasteurizer must create antagonistic pressure to help balance the pressure in the box, remove the gas in the box out to reduce the pressure inside the box, reduce the oxidation of nutrients, metal corrosion, emission development of aerobic microorganisms .
