Feed safety : Research : Botanical impurities
The mandatory monitoring programs in the member states of the European Union contain monitoring of undesirable substances of botanic origin. The extent to which this monitoring is actually conducted has recently been investigated. The report can be down loaded from this page.

There is an overwhelming amount of publications on the chemical analysis of phytotoxins. Special interest goes to the opportunities in which visual and chemical analysis complement each other.
