Malachite green in food [PDF]

EFSA Journal, 2016
Abstract Malachite green (MG) has been used globally in aquaculture but is not registered for use in food‐producing animals in the European Union. The European Commission requested EFSA to evaluate whether a reference point for action (RPA) of 2 μg/kg for the sum of MG and its major metabolite leucomalachite green (LMG) is adequate to protect public ...
