Genetic Modification (GM)


Genetic modification (GM) is a technology which can be used to produce plants with particular characteristics, for example resistance to pests or greater tolerance to drought. You can read more about GM on the Food Standard Agency website.

Our approach

We do not allow the use of GM ingredients in Tesco branded products. Any non-Tesco branded products which contain GM material are clearly labelled in accordance with EU and UK legislation so customers can make informed choices about the products they buy.

We do not prohibit the use of GM feed in the production of our non-organic meat, eggs and milk. We offer an organic range for those customers who prefer to avoid products from animals who may have had GM feed. Animals used to produce all our own-brand organic range of meat, eggs and milk are reared on non-GM feed.

Before a GM organism can be marketed as food or feed in the UK or Europe, it must be authorised. The authorisation procedure includes a safety assessment by the European Food Safety Authority (EFSA) for products sold in EU member states and Northern Ireland, and by the UK Authorities for products sold in GB.

We will continue to listen to our customers, monitor scientific research and be guided by the European Food Safety Authority and UK Food Standards Agency’s advice on this issue.
