NITROFURANS IN POULTRY: USE, CONTROL AND RESIDUE ANALYSIS - Agricultural Research Updates - page 36

precise.All the developments made during last decade allowed the imposing of
a Minimum Required Performance Limit (MRPL), set to 1g kg -1
concentration. Subsequently, the EU evolved towards zero tolerance, which
poses novel questions. This tendency implied the existence of guidelines for
the validation of both screening and confirmatory analytical methods, so as to
prevent the fluctuation of decision limits.
