Validation by U.S. Department of Defense
The CN-30 detector uses technology developed for the U.S. Department of Defense counter-terrorism agency, TSWG. The detector was developed as part of a larger Kit for detecting a wide range of poisons in food. Its function was independently and positively validated, and is the only set of detectors for poisons in food that has been positively evaluated by the U.S. Department of Defense.
You can see the CN-30 detector as part of the larger, KT-06 detection Kit, online at: http://www.tswg.gov/subgroups/cbrnc/detection/detection-of-toxic-adulterants-in-food.html.
Validation by North Carolina State University
An independent technical validation of the detection technology has also been performed by the Department of Food, Bioprocessing and Nutrition Sciences at North Carolina State University.
It concluded that "Our overall opinion is that (the) detectors for poison in food readily detect dangerous levels of poison yet they respond very rapidly an dare easy to use even by a layman".
