EFSA estimated the highest intake at 3.3 µg/kg body weight per day (adults, 95th percentile) and judged the margin of safety against kidney damage in mice sufficient, given the conservative estimates and limited uses. EFSA concluded that E586 is acceptable for preventing melanosis (black spot) in shrimps and related crustaceans, provided residues in crustacean meat do not exceed 2 mg/kg.
