Abstract

We propose a system utilizing small color-coded plastic particles to identify acute toxicants in digestive tracts and baits without chemical analysis. Test results show that the coded particle is suitable for incorporation into various baits, does not cause bait aversion, and is readily recovered from digestive tracts and fecal samples without loss of code integrity. Toxicant identification in coyotes poisoned secondarily after eating rodents is demonstrated. The proposed concept of toxicant identification is feasible. We suggest that the identification system be included in the manufacture of toxic baits.
