I find the general report a touch disturbing.

The term 'unidentifiable meat' is very worrying. Rat, fox, cat.... we simply don't know do we?
I really think it time that trading standards named these sub-standard premises. They are there, after all, to protect the consumer. From this report, I'd also expect to see at least one prosecution. - I won't hold my breath.
You missed out Badger as possible mystery meat. ;)
I never buy takeaways, nor would I buy the frozen stuff from Iceland.
I think I'd better reconsider having a pizza now. Although Papa John's look pretty safe and clean. I usually get vegetarian to be on the safe side.
There's only one way to know what goes into your food, and that's to buy from reputable local sources and cook it yourself.
After the horse-meat fiasco I no longer trust the supermarkets with meat.
