Good to Eat?

Eighteen years ago, a packet of Nestle Clusters fell down the side of the cupboard. I’ve just managed to get it out now by virtue of a length of string and a pebble-weighted piece of discarded plastic packaging with a hefty layer of glue on the bottom.

Question is – will the cereal be good to eat? The packaging hasn’t been opened and the expiry date is only March 2003.
