The pig's head cooked at nine o'clock in the evening will go bad the next morning if it is not put in the refrigerator at about 19 degrees.

Pig's head meat is not completely cooled after it is cooked at 9: 00 p.m. If it is kept at room temperature all night, the weather will be about 19 degrees, which will lead to food deterioration. When food is exposed to room temperature, bacteria will grow rapidly and lead to corruption. Especially animal foods such as meat, it is very important to preserve them at the right temperature and time.
