Exploration of Expiration: How Long Food and Other Storebought Items Last

Last year we had a box of frozen salmon I had purchased at our local grocery store the week before. MrsO cooked it up and served it. I took a bite and it was like cardboard. YUCK. Not edible. Checked the package and the due/use by date was 2009 ! Complaints at the store got me a $25 gift card, to the frozen fish company a coupon for two new meals. I check things like milk and juice, but who would have thought I needed to check frozen food? I do now. I would hope the folks that stock the frozen food section rotate the products carefully.
