There are low-tech versions of spoilage alert. oxygen sensitive stickers that change color if too much o2 detected inside the package..

However - there is one food label that I have always wanted on meats: slaughter date, freeze/pack date, sell date, cook date, eat date.

So if I go to the store and there is meat in the freezer - when was that meat caught/slaughtered/packed/frozen.

Am I eating something a year old?

If you had that labeling - I would be willing to bet that healthier eating habits would ensue - not that the meat industry would prefer it though..
