Genetically Modified Organisms (GMO) Testing and Certification

Genetically Modified Organisms (GMOs) undergo DNA structure modifications through biotechnology. Food manufactured with or containing GMO ingredients is considered Genetically Modified (GM).

GM technology has developed in response to the challenges of feeding an ever-growing global population to create genetically engineered crops that are to be pest, virus or climate-resistant.  The potential risks, benefits and ethical concerns of the presence of GMOs in the food chain are still being debated and researched.  In response, GMO content in food is strictly regulated as consumers seek to make informed choices about the food they eat.

GMOs can enter the food chain in a variety of ways. Crops can be intentionally modified or GM ingredients can be added to animal feed, however they can also enter the food chain unintentionally - as an untested ingredient, for example, or through the windblown distribution of GM seeds. Alongside the need to meet regulatory and consumer demands, this makes GMO testing essential for producers, suppliers, distributors and retailers alike. 

At Intertek, we offer comprehensive GMO detection services for food and feed and a certification programme to verify GMO-free production.

We use qualitative methods to quickly determine the presence of target GMOs. Each testing gene specifies the target sequence. The identity of any detected target sequence can be verified by an appropriate technique (for example by restriction enzyme analysis, hybridization or DNA sequence analysis). A qualitative result clearly demonstrates the presence or absence of the genetic element under study, relative to appropriate controls.



Utilising the latest methods and technologies, we provide fast turnaround times and accurate test results that demonstrate compliance with statutory requirements.  Quantitative testing determines the amount of the GMO DNA present in the sample. We use polymerase chain reaction (PCR) based testing methods and apply rigorous controls to effectively eliminate false positives and negatives. This test is offered after samples test positive for GMOs ingredients in the qualitative test or can be used as the primary testing method if requested.



Complementing our testing and detection services, our industry recognised non-GMO certification programme can help verify that your processes and products are entirely GMO-free, through on-site inspections/audits, sampling and documentation reviews.



As well as GMO detection, our world-class specialists are engaged in ongoing research and development to understand and develop testing procedures for new and emerging GMOs.



Along with analytical expertise, we also offer day-to-day support and consultation services.  With our experience and cutting-edge facilities, you can be sure that you’re protecting your customers and brand while fully complying with food safety regulations.



GMO testing forms an essential part our organic food certification services and is just one of a suite of services we provide for ensuring the safety and quality of your products. Our full range of food testing services covers microbiology, shelf life testing, GMO and food authenticity, sensory analysis, allergens and legionella.
