Me too. Long expiration dates on A2 milk products with no issues.

We buy lactose free milk and the expiration date is way further out than regular milk, not sure why. We keep it on the glass shelves and have never had a problem.

sometimes the milk can set outside on pallets when delivered to store...light is the worse thing for milk

Milk is usually good beyond expiration date, I have milk now with expiration date Dec 11, today is Dec 20.
I will finish the gallon today.
My temp in refrigerator 38*
4 things that contribute to milk going bad before expiration date.
1 Exposure to outside temp.before loading on truck, rarely the problem.
2 Delivery truck temp in route,rarely a problem
3 Exposure to outside temp. When unloaded to dock at store, how long on dock before loaded in cooler.
4 After you remove from store cooler, continue shopping, take to car, load in Fla Temp car, take home, unload and get in refrigerator, CRITICAL TIME IN FLA.TEMP. Yes never place on door,always on shelf. Big volume stores, such as WALMART,WINDIXIE. PUBLEX are pros in handling milk, turnover in milk is high.
My experience as a retired supermarket supervisor , is as many threads wrote,
I would put my money on 1 of the 4 things I mentioned.
The number 1 thing to try, is placement of milk on shelf, LOWER TEMP TO 38*
If you are buying milk at 1 of the 3 places I listed.
YOU may be the problem.
As In all food items, dates on products are used for stores to monitor rotation by stockers. Dont throw away a product unopened or with an expiration date reached, 99% of the time it is good way beyond that date.
EXPIRATION 101

Check your refrigerator temperature

Buy A2
 

While more expensive, A2 products last 4-ever. I buy the 2% variety. Well worth the money and often on sale at Food Lion (in my home town). I often buy two cartons at a time and keep the back-up in garage fridge. An open container can last up to two weeks and It has NEVER (ever) gone bad. I typically get the store brand 1/2 & 1/2; no issues there either -- also buy duplicates, keeping backups in garage fridge. All products stored on middle glass shelf in both locations.

Check the temperature in your fridge to make sure it is keeping things cool enough.

40 degrees is at the high end. Mine is set at 37, and milk is stored bottom shelf in the back. Problem solved.

Same here. We keep our fridge at 37 degrees also. We don't use much milk, mainly 2% for cooking, in 2-quart plastic bottles. The only time it goes bad is if it has been there three weeks or so and that is with a lot of bottle openings and closings.

My GE profile refrigerator recommend temp is 37^. I keep it at 35^. No problems with milk spoiling.

Our house is set at 77. We keep our milk on the refrigerator door. It is 1% milk purchased at Walmart. Never had a problem. The 1/2 gallon we bought on Sunday has a date of 1/2/23. Our refrigerator is set at whatever the manufacturer recommended. I guess I should find out what that is, just to know.

A sell by date of late January seems too far out to me. Hope the problems are resolved soon for those that have them. Seems like a variety of factors are in play here

You are correct. Maybe mention this to the store manager. I have had this experience too. This is not usual for milk, 1/2 & 1/2 creamers, etc. Even if the refrigerated trailer's AC did turn off the insulated walls are capable of holding the tempeture for a period of time if the doors are not opened.

Check your refrigerator

It sounds like your refrigerator is not working well enough. Put a thermometer in it to see if the temperature is as low as it needs to be. Clean out the lower area where dust and dirt might be clogging the refrigerator fins.

I have only used Parmelat milk. It is stocked with powdered or condensed milk. Prior to opening it requires no refrigeration and can be stored in a pantry. It comes in both whole and low fat versions. Give it a try!
