What kind of picture is honey bad?

Honey has a long shelf life and generally does not deteriorate and expire. If honey has expired for a period of time, but there is no solidification, whitening and other phenomena, you can still continue to drink. The nutrients in honey are not destroyed and there is no bacterial infection. But when honey becomes thin, white, even caked, or becomes liquid, you can't drink it at this time. At this time, honey has been fermented, its properties have changed, and it is infected by bacteria and viruses. If used again, it will cause diarrhea poisoning.
