In October 2021 Ethical Consumer viewed a questionnaire received from Suma in October 2021. This stated "uma does not stock foods that would need to be labelled as containing genetically modified organisms under current legislation. Our policy is not to purchase or stock any raw materials, packaging or finished product that contains / may contain any GMO materials or that may have been contaminated with any materials of this nature. All the foods we sell are GM-free. Please see the buying policy on our website: http://www.suma.coop/about/ethical-policy/".
The company sold one variety of long-life dairy milk, which was organic, so was not from animals fed GM feed.
Suma was considered to have a positive policy in relation to a Controversial Technology issue.
