I use wardley's shrimp pellets. I can't recall if there is an expiration date on the can, but it won't hurt to check. I suspect the can in the initial post sat on a shelf too long.
However, wardleys' pellets are not going to be for sale much longer as a couple months ago they announced they were discontinuing them for some reason - which I don't believe had anything to do with bad product.
