The Public Inquiry was set up by the National Assembly for Wales to undertake a thorough investigation into the outbreak and is being led by Professor Hugh Pennington.
Chairman of the Inquiry Professor Hugh Pennington said: 'We know of many people and organisations that were affected by the outbreak or involved in it, and we are in the process of contacting them for information. However, there may well be others who have relevant information on the outbreak or the way it was handled. As I've said before, I am committed to involving the public in the Inquiry and this is one way in which it can reach out to people. This way, anyone who feels that they have any information that could help the Inquiry in its work has an opportunity to come forward.'
