Greenpeace directly criticise U.K. supermarkets for selling threatened fish species and urge them to sell seafood from sustainable sources only. Supermarkets are also criticised for stocking, and thereby promoting the development of, genetically modified (G.M.) products.
Some people may wish to boycott supermarkets completely in an effort to lead a fully sustainable lifestyle. Although all major U.K. supermarkets have undertaken promises to remove G.M. products, campaigners from major pressure groups point to some major problems with this:
- Meat products from animals reared on GM foods do not currently count as GM foods.
- Under current regulations, there is allowed to be a presence of 0.9% G.M. produce in a food that is labelled as 'non-G.M.'
- There are still traces of G.M. food in ready-made meals, that only have to be declared in very small print on the back of the packaging.
- Letting them know that you are dissatisfied with their policy on sustainability issues in general and particularly: policies regarding the sourcing of produce (which often comes from afar, demanding high fuel expenditure); their policy on G.M. food; their policy on sourcing fish and any other products that are threatened with extinction. You can let them know directly, by writing to their customer relations departments, filling out a comments form in-store, or lobbying your local M.P.
- Boycotting them.
- Rewarding supermarkets, such as Marks and Spencer's, who source food completely non-G.M. food products only. This will put further pressure on other supermarkets to change tact.
- Asda: Asda aim to sell organic produce at an affordable price, and are committed to sourcing products from local companies and currently offer 3,000 local products across the U.K.
- Marks and Spencer's sell the biggest range of organic meat products from animals that are reared on non-gm food. Not only are Marks and Spencer's eggs free-range, but all eggs used in their products are free-range too. Where possible, Marks and Spencer's source foods from the U.K.
- Sainsburys: Sainsburys have stopped selling Skate and Husk, which are endangered fish. They also are committed to sourcing their organic eggs from chickens free to roam in woodland. They sell organic beef, and have plans in place to shortly source 70% of all organic produce from the U.K.
- Waitrose claim that they use absolutely no G.M. produce in their own brand food. Waitrose sources 89% of its organic food from the U.K. and has the widest range of organic food on offer, out of all of the major supermarket chains.

There are plenty of soy or gluten products that look, taste and feel like meat which could be used instead.

An in store manager told me they had no GMO in their cheese production, I called customer services, they reiterated this claim. I told them I did not belief them, and could they tell me what rennin substitute they did use. He could not tell me, but said someone else would call me.
I was then contacted by M&S, again I was assured that no GMO was used in any of the vegetarian cheeses. I asked could he confirm this in writing, I was going to have the cheese tested.
I received a letter from M&S dated 3rd February 2011, in it they admitted they do in fact use the GMO ingredient chymosin in all their cheeses!!!!
Only for my persistence, and threat of having the cheese tested they would not have told me the truth! I have now contacted media, environmental health, food standards etc. As they by law should have it labelled GMO and they do not.
I myself had told people to use M&S because of the GMO policies. They have lied, lied and lied again to me, but eventually the truth came out.
If you want confirmation of this, I will gladly email you the letter I received from them.
I am now wondering if they have lied so blatantly about this, can we trust them with all their other GMO claims!
