Introduction
There may be a large number of bacteria, such as Escherichia coli and Staphylococcus aureus, in expired milk. These bacteria may irritate the gastrointestinal tract, causing gastrointestinal discomfort symptoms such as abdominal pain, diarrhea, nausea, and vomiting. In severe cases, they may even cause food poisoning, with symptoms including dizziness, blurred vision, loss of appetite, and fever.
Generally speaking, milk that has expired by four months should not be consumed. The analysis is as follows:
There may be a large amount of bacteria present in expired milk, such as Escherichia coli and Staphylococcus aureus. These bacteria may irritate the gastrointestinal tract, causing gastrointestinal discomfort symptoms such as abdominal pain, diarrhea, nausea, and vomiting. In severe cases, food poisoning may even occur, presenting symptoms such as dizziness, blurred vision, loss of appetite, and fever.
After milk expires, its nutritional components, such as proteins and vitamins, may have already deteriorated and lost their original benefits. Additionally, the fat in the milk may oxidize due to prolonged storage, producing an unpleasant odor. Consuming such spoiled milk offers no benefits to the human body.
As milk expires, its taste also gradually deteriorates. Expired milk might emit a sour or foul smell and may even develop clumps or sediment. These changes indicate that the milk is no longer suitable for consumption. To ensure food safety, it is important to follow proper storage guidelines, such as keeping milk refrigerated and avoiding placing it near the door or heat sources.
