In july 2020 Ethical Consumer searched for information on Marks and Spencer's GM policy. A questionniare response that had been received from Marks and Spencer in March 2017 was still assumed to apply as no evidence could be found to the contrary.
In response to a question regarding the company's policy on genetic modification, it was stated: “M&S Food is not made with genetically modified ingredients nor the use of nanotechnology.”
In relation to genetically modified ingredients in animal feed, it was stated: “Due to a lack of non-GM animal feed available to UK farmers, we, alongside other retailers, do not stipulate the use of non-GM animal feed in our fresh meat supply chain.”
Ethical Consumer also viewed the M&S website which contained a policy on GM. It stated "Marks & Spencer are committed to providing foods which do not contain Genetically Modified (GM) ingredients or derivatives.Our definition of ingredients and derivatives covers any substance, including additives, used in the manufacture or preparation of a product which is still present in the finished product, even if in altered form." This was not considered to cover GM animal feed.
Due to the fact that the company was likely to be selling meat from animals fed a GM diet the company lost half a mark in the Controversial Technology category.
