So I had chicken in my fridge which expired today. Last night I cooked it, made it with pasta. Before cooking I could tell the chicken had a slight smell to it nothing rancid mind you but i've smelt chicken with that smell before. anyway i made sure it was cooked and today i had some and some of it tasted funny so i chucked it. Got some gi symptoms like flactuence etc not sure if they can start this soon (had it less than an hour ago) ? it didnt' expire until today so can't believe it would go bad before the expiry date.
