Generally your local health inspectors do that kind of checking. Most items say "Best if used by _____" rather than listing as a don't use beyond date. The exceptions to this are fresh meats, where the look of expired meat is generally going to be a turn off to purchase. In reality, even vacuum packed materials are dated well before a time when they might be dangerous. Many canned and dried materials will be good for years past their 'expiration' if stored properly in a cool, dry place. So it really comes down to the store themselves to police/patrol this stuff. The other issue is that some products have a 'packed on' date rather than a 'use by date'.
The Albertson's that used to be in my market had a policy that items were 'its fresh or its free'. They were huge abusers, especially in meats, of selling out of date product. While initially they gave you the out of date product free, either public pressure or health department pressure was brought to bear and if it was out of date you got a fresh dated one free. I used to wander through their meat department and load my cart with two similarly priced items--the out of date one and the fresh dated one--to head for the register. I did not dare show my hand in the meat department or they would run ahead of me pulling out of date materials because they KNEW what was out of date but were trying to sell it anyway. I did not dare leave my cart unattended because as soon as the meat department spotted me I would be shadowed through the store and out of date products were literally removed from my cart and 'disappeared'. We did a lot of hams and sausages and corned beefs as my kids were growing up based on the 'fresh or free' promotion. In the early days of it there were times when I left the store with hundreds of dollars worth of free meat, eggs and cheese.
These days most groceries in my area either give stuff to the Food Bank as it is approaching expiration or mark it down a day or two in advance of expiration. I recently picked up several 'family packs' of Purdue chicken breasts and thighs where there are interior freezer packs that are the perfect portion for 2 people. These were "Use or freeze by" dated 2 days in advance and were marked down to less than half price. They were obviously part of a big over order mistake as they were being brought out from the back still solidly frozen and popped into my freezer still solidly frozen. One of the few times in recent history I spent money on groceries that was not reimbursed for a shop.
Edited to add: As for Food Lion . . . they are no longer around here, though I understand they still exist in some markets. I was in the store one day when the deli gal was pulling the vacuum pack cheeses such as Kraft, cutting the mold off and rewrapping them in saran to sell as house branded loose chunks at a per pound price higher than the original Kraft. I put back the groceries I had in my cart and left empty handed.
