Ray is Emeritus Professor of Food Safety at the Natural Resources Institute, University of Greenwich, and owner of Raymond Coker Consulting Limited.

He has been involved with the international management of food & feed safety for over thirty years, specialising in the control of mycotoxins (potent fungal toxins) in food and feed throughout the globe. He has advised a variety of national and international bodies including the Food Standards Agency (UK), EU, Department for International Development, USAID, and UN agencies (including FAO, WHO & IAEA), and has led a variety of international, multidisciplinary projects.

Ray has worked in Europe, South & S E Asia, China, Africa and North & South America.

He founded ToxiMet Limited in 2005, in order to develop simple, affordable, accurate and robust technology (the ToxiMet System) for the accurate measurement of mycotoxins in foods & feeds, throughout the global supply chain.

Ray established a further company, Raymond Coker Consulting Limited, in 2013.

Ray has contributed over one hundred articles to learned journals, books and other specialist publications, as well as attending international conferences in Europe, Asia, Africa, North & South America as an invited lecturer. He has eight granted patents or patent pending.

Ray is a natural products chemist who initially studied medicinal plants. Subsequently, he devoted the rest of his career to addressing the occurrence and control of mycotoxins in foods and feeds, throughout global supply chains, including the development of:

• Sampling and sample preparation methods for the production of accurate analytical samples, of a variety of foods and feeds, from small batches to batches of tens of thousands of tonnes.
• Methods (e.g. TLC, HPLC, HPTLC, ELISA, biosensor) for the quantitative analysis of mycotoxins in a wide variety of commodities.
• Surveillance procedures for the accurate evaluation of the mycotoxin contamination of food and feeds in specific regions.
• A commercial process for the detoxification of aflatoxin-contaminated animal feeds.
• Biological methods (e.g. using engineered baker’s yeast) to evaluate the toxicity of a variety of mycotoxins.
• Patented technology (ToxiMet System) for the accurate measurement of mycotoxins, by non-scientists, at factories, warehouses, docksides etc throughout the global supply chain.
• Distributed ledger technology (e.g. blockchain), as a platform for the enhancement of the efficacy of tools employed in the management of food & feed safety systems.
• Patented soil testing technology (Safe Soil Tester) to simply & rapidly detect contaminants on brownfield sites, prior to attempted remediation.
