Purpose of the consultation

This consultation provides the opportunity for stakeholders’ views to be submitted on the authorisation of feed additives and PARNUTs. The FSA will consider stakeholder feedback to inform ministers in England and Wales, with the Minister of Health for Northern Ireland kept informed, before they make a determination.

We are seeking feedback on the proposed terms of authorisation, our assessment of the potential impacts detailed in the consultation pack, and any further evidence you may have on additional impacts that we should consider.  

A parallel consultation is being published by FSS to equally inform ministers' determination in Scotland.
