Something interesting they wrote up was:
DECODING EXPIRATION DATES
(Known to those in the supermarket as “Pull Date”)
The “Sell By” date is most common with dairy products, packaged salad mixes and is also found on your favorite Hillshire Farm Lunchmeat container. This is the date that your store must remove the item from the shelves if it has not been purchased. Rest assured, if it is January 3 and you are staring at a “Sell By” date of January 4, it is ok to go ahead and buy the product, if you will consume it within the next 2-3 days.
Typically found on packaged dry goods, condiments and some canned goods, the “Best If Used By Date” is a suggestion for getting the best taste out of the food. The important thing to remember about “Best If Used by Dates” is that it is all about the freshness and taste of the food.There are three different terms used to let you know when your food is no longer edible. Why are there three, you ask? Understand that this information was not created to confuse you (that’s just a cheerful side effect) but actually to help you. And we want to help you help yourself:
While all of the codes are typically referred to as “Expiration Codes,” a true “Expires On” label is usually only attributed to baby formula and food, over-the-counter drugs and vitamins. Expiration dates are serious business and mean the absolute last date that a product should be used

Ever since I was a teenager, I worked at a dairy company.
Milk, Ice cream, eggs and bread-the whole 9 yards. I have experience from the most lowly part-time clerk in a retail convenience store to Senior Staff Accountant, Dairy Plant Cost Accountant and Assistant to the Controller (25 years later)
I still cannot spell but I assure you all that there is no, there never was and there never wiill be a TIME BOMB in your food.
(Such a concept is simply not cost effective)
Your milk, eggs, bread etc…will not automatically go ‘off’ on a certain date.
Trust me on this-and use this information to your own personal ‘profit’. I ALWAYS shop the ‘Managers Special’. Even meat. Even CHICKEN!
I will give you a good ‘rule of thumb’. Maximum shelf life is contingent upon proper handling. Especially with highly perishable meats and dairy. (Don’t even get me STARTED on ice cream-ice cream is delicate….like fine caviar.)
Barbee’s rule: USE YOUR NOSE. It smells okay-it’s probably okay.
Pork smell like fish-don’t eat it.
Crab smell like ammonia-don’t eat it.
You get the idea?
Know this: A 1/2 gallon of milk can conceivabaly last ONE MONTH under proper conditions. You leave that same 1/2 gallon of milk out on the kitchen table for an hour in the Summer-you got garbage.
Barbee those are words of wisdom. I have sour cream in the garage fridge that is a month or two outdated. Someone is probably going eewwwww right about now, but what exactly do you think “sour cream” is!? When I open the lid on these expired containers I know it is a one date use. I won’t save it when it is that outdated because my experience is it quickly goes bad once the plastic seal on top is compromised. Until then, I will continue to stock-up on free sour cream and use it whenever I get around to it.
