Can Wuxi manna herring be eaten if its package is leaking?

It is recommended not to eat, because the requirements of vacuum-packed food are still different from those of daily stored food. Vacuum packaging, also known as decompression packaging, is to pump out all the air in the packaging container and seal it to keep the bag in a highly decompressed state. The lack of air is equivalent to the lack of oxygen, which makes microorganisms have no living conditions, so as to achieve the purpose of fresh fruit without disease and rot.

Therefore, after the vacuum-packed food leaks, the food comes into contact with the air and is easy to oxidize, leading to food deterioration. So don't eat it.
