Various information and list of all slaughterhouses and cutting plants in England, Wales, Scotland currently approved for halal or kosher production

Your request was about the following information:

Q1. A list of all slaughterhouses and cutting plants in England, Wales [Scotland] currently approved for halal or kosher production, with the name of the halal or kosher certifying body under which they are approved. 
Q2. Any records held by [FSA/FSS/DEFRA/APHA] that identify which certifying bodies are recognised for export purposes, and which UK establishments are approved under each of those bodies. 
Q3. If available, the volume of slaughter or processing carried out under each certifier, by establishment, for the most recent year available.
 

Food Standards Scotland (FSS) are unable to supply this information as we do not specifically approve Halal and Kosher production, and therefore don’t keep a log of the certifying body.
