Radioactive contamination of food and feed can occur through air, soil or water, presenting serious risks to human health and to your business. Radionuclides, such as Cesium-137 and Iodine-131, can accumulate in crops, seafood and terrestrial animals, leading to import refusals, product recalls, danger to health, or long-term reputational damage.
Our advanced radionuclide testing services enable you to detect and quantify radioactive isotopes across a wide range of food and feed samples. With reliable data from our accredited laboratories, you can confirm compliance with global limits, protect consumers and demonstrate due diligence across your supply chain.
Verify that your food and feed products are free from unsafe levels of radioactive isotopes.
Meet international radionuclide limits and avoid costly import refusals or product withdrawals.
Identify contamination risks from soil, water, air, facilities or transport, ensuring full supply chain integrity.
Show your commitment to food safety with independent testing and certification.
As the global leader in testing, inspection and certification, we combine in-depth technical expertise in food safety and environmental science with an international laboratory network to deliver fast, reliable and comparable results. Our services cover radionuclide detection, quantitative analysis and certification programs, including the SGS Nutrasource Radioactivity Tested & Certified™ Program, giving you and your stakeholders confidence in product safety.
By partnering with us, you benefit from world-class capabilities, decades of experience in food testing and a trusted mark recognized worldwide.
Contamination can occur through:
We test for a wide range of radionuclides, including Cesium-134, Cesium-137 and Iodine-131, using advanced methods such as gamma spectrometry and liquid scintillation counting.
This program offers per-lot testing for I-131, Cs-134 and Cs-137, with strict limits below international thresholds. Certified products carry a visible mark, giving consumers assurance of safety.
