This all makes massive sense to me. The people in my life treat any date on food as an expiry date and throw out massive amounts of perfectly edible food. Also, people do not seem to have any concept about the rate at which different food products spoil. Some things can be used way past the dates I see. Others really are going off by then.
Meanwhile we have gotten rid of expiry dates here in the UK. And I have bought fruits and vegetables that all look fine on the outside but inside are rotten. Not only frustrating this then wastes my time and my money. Items do need expiry dates, sugar does not, fresh produce and vegetables do. However, educating that your food isn't instantly bad when it's gone pass would encourage people to waste less food.
It's great! Now the supermarkets can blame us for waste.
Fortunately, every supermarket does still have labels that show a coded date - so that their staff can remove products that are too old.
If you search for the particular store online, you should be able to find their system.
I shop in Sainsbury's usually. Their system is pretty simple. A letter shows the month (A = January, B = February etc.) and two digits show the day of the month.
