I had a jar of Kraft mayonnaise go bad on me a couple of days ago. It was just reaching it’s “use by” date. I first noticed it did not taste quite right so I smelled it and sure enough it was bad. The thing which makes me a bit concerned is that my refrigerator is very cold. I had used about two thirds of it.
I called their toll free number and they are sending me a coupon. Still it should not have happened.
I’ve had Velveeta go bad before the expiration date. Now, it goes straight from the grocery store to the freezer.
