摘要：
A method is described for treating consumable products, such as foods, drugs or dietary supplements, for example drugs enclosed in capsules, to detect contamination. A colorimetric indicator, which can react with a contaminating substance such as cyanide, is incorporated into the consumable product or the packaging for the product. When the indicator comes in contact with the contaminating substance, a readily detectable color signal is produced.
