GM on the shelves

In the UKmother and child looking at a jar of jam in the supermarket GM products have to be labelled but the text is not always easy to read. This page lists the GM products that we’re aware of, for sale in UK shops.

See our GM for sale page for tips on the most effective ways to let shops know that you don’t want to see GM on the shelves.

GM trick no treatHallowe’en Horrors

One of our supporters spotted these GM sweets on sale in Waitrose, in October 2022.

Special ranges like those that flood the shops in advance of Hallowe’en, Christmas and Easter can be more likely to include GM ingredients, especially if they include items imported from the United States.

Keep your eyes peeled and let both the staff in the store and those at headquarters know that you don’t want to see these scary sweets on the shelves.


Packet of M&Ms CrispyM&M’s Crispy –  RECALLED

In August 2021, various specific bags of M&M’s Crispy products (in blue bags) were recalled by major supermarkets including Asda, Sainsbury’s and Tesco due to the presence of an undeclared GM ingredient.

We understand that GM rice flour, which is not authorised for sale in the UK or across Europe, was illegally imported from India and used in the production of these sweets. If this is true it is a serious breach of food safety laws and may affect other products. We will update this page if we find out more.


Soylent meal replacement drink

This controversial US product, made from GM soya, is apparently on sale in the UK from 20 September 2018. The formula had to be adjusted to comply with our regulations but, as far as we know, it will still be based largely on a GM crop.


Illegal GM petunias

Unauthorised, untested orange GM petunias were spotted on sale in garden centres in the UK in 2017. We are told that they have now been withdrawn but as there are no naturally orange petunias, if you spot any orange ones we recommend steering clear and letting staff know that they may be unwittingly selling illegal GM flowers.


KTC cooking oil

Side of packet of KTC blended olive pomace oilMost KTC products are not GM but some of their cooking oils are. Watch out for olive pomace oil, extended life cooking oil and oil marked simply vegetable oil, all spotted in Tesco, Sainsbury’s and Asda.

Watch out for GM cooking oil used in restaurants and take-aways. It should be declared on the menu, but we know that some establishments are not doing so.
