II. Pure Milk

Pure milk is a popular breakfast choice for many, as it is rich in protein and trace elements such as calcium. However, in some cases, pure milk can spoil before its expiration date.

If the outer packaging of pure milk shows signs of bulging or other abnormalities within its shelf life, it indicates that the milk has been contaminated with bacteria.

Bacteria multiply in milk, producing gas and causing the packaging to bulge. Milk in this condition should absolutely not be consumed; drinking it may cause food poisoning symptoms such as vomiting and diarrhea.

In addition, even if the milk packaging looks normal, if the milk becomes thick or has lumps after opening, it means that the milk has spoiled.

Pure milk has strict requirements for storage temperature. If the temperature is not properly controlled during transportation or storage, problems can easily occur.

We must always pay attention to the condition of pure milk. If there are any abnormalities, it should not be consumed and must be discarded.
