Expiration date??????

If it is still nice and green, with few to no brown spots or dry patchy areas and as long as the stalks are still crisp, then it should be fine. If they are rubbery and you can bend them without the stalk snapping, then they are probably past due and I would throw them out. If the surface looks dry and shriveled or somewhat dimpled, then I would pass also.

Pull off a stalk, bend it in half and if it snaps, cut off the ends and eat it. If it nestles together in a "U", toss it.

If it looks and feel alright, then it should be alright. There is nothing to worry about.

if u have receipt I would return it. I am sure it is perfectly fine though.
