The European Food Safety Authority (EFSA) has proposed a reduction of the maximum permitted content of zinc in feed for all animal species, including fish. EFSA said the reduction in maximum permitted content of zinc in feed ensures consumer safety, animal health and welfare, and does not affect animal productivity.
The currently authorized maximum zinc content in complete salmonid aquafeed is 200 mg Zn/kg; the new proposed level is 150 mg Zn/kg.
It estimated that the new proposed levels would reduce the amount of zinc in manure released in the environment by about 20 %. To complete its risk assessment, EFSA reviewed relevant available literature as well as data received from national authorities of European countries and from stakeholders.
