Their website states:
“Current risk assessments combined with historical evidence indicate that soft targets such as the food and water supply may represent a point of entry for terrorist attacks. Detection of pathogens or toxic chemicals in food prior to consumption will require a systematic approach that yields an immediate and conclusive yes or no answer. Appealing Products, Inc. has developed a self-contained, deployable food security test kit that can detect sublethal concentrations of toxic chemicals (cyanides, azides, and sulfides) and metallic poisons (arsenic, mercury, lead, cadmium, thallium, and chromium) in a wide range of food matrices.”
