@AMCLady :
He told me that you have to keep milk at 40 degrees or below to keep it from going bad.
All "refrigerated foods" should be kept at 41 degrees or below to retard bacterial growth....But they will "go bad"(experiance bacteria growth) after a time, the low temp only delays the process....
I like to shop for my milk at Krogers because they keep milk behind refrigerated doors.
The Aldi I shop keeps theirs in a cooler behind glass doors also...I can't think of any stores that do differently....But that is a good point, if I went into a store and saw milk displayed on refrigerated "open air" shelves, I'd definitely not even try to buy it....
