Once meat and fish is cooked it last quite a while in fridge. However, since on diet I am very careful about eating fresh and healthy food. I usually buy my meat or fish the day that I’m going to eat it. If I’m buying Salmon I ask them to cut it into smaller portions. I will stick them in the freezer to pull out and eat. If you are unsure..get rid of it. You don’t want to feed this monster. I don’t have good advice because I grew up on a farm and it seems the meat would last forever…if put in salt, smoked etc. Be safe not sorry. I even cook chicken and slice it into smaller servings and freeze to eat on salads later. I don’t let it sit around too long…mostly out of fear.
