(12)The European Union Reference Laboratory for Animal Proteins in feeding stuffs (EURL- AP) validated in 2012 a new diagnostic DNA-based method (PCR) which is able to detect ruminant material that may be present in feed. The validation of this method permitted the re-authorisation in 2013 of the use of non-ruminant processed animal protein in feed for aquaculture animals as set out in Commission Regulation (EU) No 56/2013note.
