The FEED-CODE method: a reliable DNA-based approach to feed authenticity.

Feed for producing animals represents the first ring of the human food chain. EU Regulations apply to feed the same labeling requirements as for food, but the only accreditated method for the determination of feed composition is based on light microscopy and microdissection. In the framework of the EU project Feed-code, we developed and validated a modular method for the authentication of feed botanical composition.
