My local Morrisons is bad for having mouldy food or opened/damaged packaging on their shelves. They need to pull their finger out and have someone constantly checking the shelves.
Many years ago, I did security for a Mr Kipling factory in the North West, They used to throw huge amounts of their produce away. Mainly because of damaged packaging, such as a slightly squashed box. It was padlocked in large cages so no one could get at it. (Maybe it was destined for Morrisons!)
