GMO content in food is highly regulated with strict labelling rules. We are both highly proficient in GMO testing and very familiar with the various standards that you are required to meet. With over 15 years’ testing experience, deep knowledge of the industry and extensive expertise in raw material supply chain assessment, we are ideally placed to partner with and advise you on the best approach for your business and food analysis.

Using DNA-based methodology, we perform both qualitative and quantitative testing.

Qualitative GMO detection

(positive or negative answer)

RSSL qualitative testing is UKAS (ISO/IEC 17025) accredited. We can screens raw materials and complex finished products for the presence or absence of GM soya and maize with a detection limit of 0.1%.

Quantitative GMO testing

(estimation of the amount present)

Quantitative GMO testing determines the proportion of the soya or maize DNA in a product or ingredient that is GM. We have accreditation of quantitative testing for four GM varieties: Roundup Ready Soya, Maize Bt176, Maize Bt11 and Maize Mon810.

We regularly participate in proficiency testing schemes so you can always be confident in the quality of our analysis.
