If your chicken expires on 14/7, would you still cook it and feed your family?
I would not cook it and feed to my family, i would not risk my stomach even it's on the fridge it can cause diarrhea. I just buy new and fresh meat in the market.
You are not going to have stomach problems by cooking a meat or chicken that has expired one day ago.
Companies are giving slack expiration dates for this reason. They want to protect their brands as well.
