3, can't eat.
Some people like to eat half-baked eggs. The yolk of this half-baked egg is still fluid and has not reached the mature temperature. The fungi in this yolk are still not completely killed, and it is only suitable for fresh food. After being stored for one night, the protein in the egg is decomposed in large quantities, resulting in toxic substances. This egg is not suitable for eating.
