Can I still eat the rice bag I bought that day when it is sour?

If the rice bag bought that day is sour, it is recommended not to eat it. Because sour food may irritate the mouth and digestive system, causing discomfort. In addition, if the rice bag has deteriorated, bacteria may breed, and eating deteriorated food may cause health problems. Therefore, in order to ensure your health and safety, I suggest that you don't eat sour rice buns.
