The only time Ive ever heard how long a Wal-Mart cake stays sitting in the freezer was here. I kind of always assumed the person who first said it probably didnt know that for a fact but the 6 month things has stuck and has been repeated forever since Ive been here.
Two of my BILs work for two different food distribution companies here in my state. I get all kinds of fun stuff from them anytime some guy drops a pallet and the boxes are damaged. Ill gladly take a billion pounds of butter just because the top of the box has a dent in it One time one of them offered me a bunch of chocolate sheet cakes that were supposed to go to one of the grocery stores around here but the box they were in got smashed up so they were giving them away to the guys as the warehouse. None of them knew what to do with them since they werent iced. I didnt want them either and from what I heard they threw them out. But they did sit in the warehouse for a long time while the guys up top tried to get someone to get rid of them.
From what Ive heard from my BILs sometimes the food will sit around in their warehouses for a while. I dont know exactly how long though. I can't imagine something sitting around in a freezer for 6 months before getting shipped out though.
I have never worked for Walmart, but I have worked for Meijer and Biggs, doing cakes. When I needed cake, I would don my winter coat and grab a huge cart, and head back to the freezer. At Meijer the freezer was kept fairly organized, but we would scare up 3 cases of heart shaped cakes left over from Valentines Day and turn them into Santas at Christmas.
At Biggs, I had to climb up the side of boxes stacked 20 feet high, crawl across the tops of them to the back of the freezer and dig through flattened, damaged boxes to get cakes that would literally crumble from freezer burn, even when frozen. Sometimes I dug boxes out that were 2 years expired, and the other decorator, who came from Walmart, had no problem using them. I refused. I got fired after they listened to me complain about quality and safety standards for 4 months. I thought they'd find my frozen dead body in that freezer one day.
That is disgusting. And I stand corrected.
