At-Line Analysis of Lead in Animal Feed using ED-XRF Spectroscopy
Lead ingestion is a common cause of farm animal poisoning. Even a trace can cause death, malaise, degraded performance, and render their meat unfit for human consumption. Lead can enter the animal food chain in many ways but among the most preventable methods of reducing lead contamination is to minimize its introduction into animal feed.
To reduce animal feed contamination, the Dutch feed industry twenty years ago developed a toxicology certification scheme, which is now widely adopted as an international standard. The stringent standard defines acceptable levels of contaminants however meeting the requirements, until recently, required time-consuming laboratory analysis with expensive, high performance instruments.
This paper explains how to use new, portable instruments for rapid at-line analysis that easily meets the standard.
