I gave up trusting supermarket meat some time ago. They are only interested in chasing profits, nothing else, so will buy from the cheapest supplier. Almost everything else they say is marketing.
Support your local butcher. I use two local butchers, went to one on saturday, had aged t-bone steaks, cut to the size I want. Both butchers only use local meat, Andrews in Marlborough has his own staff at the local abattoir and selects the best animals, so only the butcher touches the animals throughout the chain from when it comes into the abattoir.
You pay more than supermarket meat, but the flavour is better, it's butchered better and you have less wastage. You don't find a ton of skin or fat hidden under the meat in the cellophane wrapped product.
So it's a non issue really. The papers have an agenda to sell papers so will put a slant on a story, especially the rags recognising the rise of UKIP and their views etc.
The supermarkets will make as much profit as possible and cut corners etc where they can get away with it.
Which leaves discerning customers to vote with their feet and take their purchases elsewhere. It takes time and a little effort but the results are significantly better in the quality of food
Trouble is - most people are sheep, 1 hour in the supermarket, stock up for the week - job done, or worse - get it delivered so they have no contact with what they are buying other than to put it on their shelves, that's if it's not outsourced further to takeaways.
This country long ago lost any contact with food. Go to French local town markets, or Italy and see the quality. Even in the supermarkets the French are fussy consumers. Here the majority see it as a chore.
So don't moan, do your research. There's plenty of good sources of food out there, they just may not fit your terms of convenience.
