Agriculture is one of the industries that crosses all boundaries from countries to economic status. Over the decades, safety organizations around the world have continued to monitor and set limits for harmful contamination, additives, and pathogens in our food supply.

Our standards assist agricultural and food safety laboratories around the world in monitoring and assessing the state of global food and agriculture. Inorganic standards range from elemental impurities and inorganic species to macronutrients and packaging contaminants. Our organic standards, designed around analytical needs and international methodologies, range from pesticide testing to targeted fragrance and flavor compounds. Molecular biology kits help analysts extract DNA for species identification or allow for the testing of foodborne illness pathogens.
