Ask your supermarket to Feed you the Truth

Let your favourite supermarket know that you care what the animals that made their eggs, dairy, meat and fish have been eating.

What you can do

Go shopping

Visit one of the ten supermarkets featured in our Feed me the Truth campaign and ask if the meat, eggs and dairy products on sale are from animals that have been GM-fed.

You could ask staff at the meat or cheese counter if they know the answer, or go to customer services. If you have time, ask to speak to the manager. Whoever you talk to, please be polite but don't be fobbed off with an answer about organic products. Organic standards exclude the use of GM feed so you want to know which non-organic products you can buy without supporting GM. Tell them that:

  • You want better information about which products are - and are not - GM-fed
  • You want to buy own-brand products that come from animals that have not been fed GM crops

Please ask about own-brand products (with the supermarket's own name or logo somewhere on the packet) and focus on basic eggs, milk, dairy products (eg cheese, buttter, cream), poultry, red meat or farmed fish. Feed me the Truth banner

Write to head office

Let supermarket head offices know how much you care about this issue

We have contact details for all ten supermarkets featured in the campaign. Let them know that you want to be able to buy own-brand products from animals that have not been fed GM crops and that you already know that organic products meet this standard.


  • Ask nicely and get straight to the point. A short, polite letter usually gets better results than a long or angry one.
  • Explain why you are writing and what you would like done about it. Remember you are writing about non-organic GM-fed products – don’t get fobbed off with replies about GM ingredients, or the fact that their organic ranges are non GM-fed – they have to be so that’s really missing the point!
  • It’s also a good idea to thank the company for dealing with your complaint as it ends the letter in a positive manner.

Background to this action

GM Freeze is urging the UK's top ten supermarkets to Feed me the Truth about GM animal feed.

Most non-organic farm animals in the UK are given genetically modified feed, despite the fact that none of the crops they are fed can legally be grown here. The crops they are eating are designed to either tolerate repeated spraying with particular weedkillers (usually glyphosate) or produce pesticides within their own cells. They are associated with some of the most damaging farm practices in the world and are harming people, animals and the environment.

GM ingredients have to appear on the label, but GM feed does not need to be mentioned so consumers are being kept in the dark.
