With 4 kids, we've been buying milk by the gallon for the last 15 years. As 2 kids have moved out, we haven't dropped back to the smaller size container, and it now sits longer in the fridge. As Mrs BamaVol and I were finishing breakfast this morning, she made a face and asked what was the expiration date on the milk. I looked and it was 7 days ago. Both of us had a bowl of cereal with a half cup or so of milk. I hadn't noticed anything myself. She didn't until she took a spoonful of milk after the cereal was gone from the bowl. She sniffed the milk container and gagged.

It's 2 hours later, and other than a little "growly in the bowely", we're both ok.
I've always viewed the date on the milk as a sell by date.

When does the milk become dangerous?
