Studies have shown that frozen foods such as meat, fish, seafood, etc. are easily deteriorated if stored for too long. It is difficult to be destroyed even when heated at high temperature. After people eat it, it will cause gastrointestinal poisoning, causing nausea, vomiting, abdominal pain, diarrhea and other symptoms of varying degrees.
It is also reported that a Yersinia bacterium that is widely present in poultry and livestock animals can still grow and reproduce in a low temperature environment of 0°C to -4°C. The refrigerator has become an excellent breeding ground for it. Food stored in the refrigerator for too long, and contaminated food is not fully heated before consumption, can also cause intestinal infection.
To this end, relevant experts remind people: every few days to clean up the family refrigerator. Especially for fish and seafood that have been stored for a long time, you should carefully identify whether their color and shape have changed; for food that has been frozen for more than 2 to 3 months, you must be cautious when eating. Don't think that food is safe in the refrigerator. In fact, the refrigerator is not a "safe".
