Thank you very much for the question.
Let me begin on the issue of the statement that was made. The statement said that with the current restrictions we have in place, we are removing upwards of 99% of known infectivity for BSE from the food chain. So in terms of those tissues that are defined as specified risk materials--brains, spinal cord, eyes, various other nerve bundles, tonsils, and certain parts of the small intestine--the cumulative work of research suggests that although there may be micro other elements in the animals that we will still find with additional research, the materials that we have defined and are removing cover about 99-plus per cent of all known infectivity. And in removing that, again, as we said, we have done the modelling and we would be pleased to share with you and the committee the modelling work that has been done and previously published in various fora around the timeline projections of having moved to that level, how that decreases the eradication time period. So we will be pleased to provide that to you and the committee.
With respect to implementation and update and further discussion around the work of the industry and governmental working groups in terms of the assessment of the impacts and suggestions, again, with the permission of the chair, I would ask Mr. Libby to come back to the table, if that's possible.
