So I'm an expatriate at a totally new place, and all bread sold in here got 2~4 days expiry and I usually don't finish it in that short period of time, I always store all kinds of breads and pastry/bakery in the freezer, and get them out before using by few hours, then get the rest back to the freezer. So I was wondering is it safe to eat an expired bread? The color and smell of the bread never changed at all.
If it might make any difference, the type of bread I'm referring to is pita bread.
