When it comes to eating turkey bacon, there are some things to look for. The natural pink color of turkey bacon is due to the fat in the meat. If the turkey bacon is beginning to spoil, its color may change from pink to a gray or brown shade. This color change will start slowly and can be subtle.
The smell of turkey bacon is another way to determine if it’s rotten or good. Fresh turkey bacon will have a unique smell, but a rotten one will be sour or fishy.
