Since the recent loss of dates I am struggling with buying fresh veg. I know if it looks ok, it is ok, but I have a ridiculous need to buy the freshest product on the shelf. Before that would be the one with the longest date, but now things are marked '015' '016' etc. Can anyone tell me if the higher number is simply the newest or if there is some sort of secret formula 
Just want to add I am not looking for opinions goading me into justification. I am autistic and genuinely can't help this nonsense when shopping.
