Just to be clear, there has been a regulatory requirement in legislation for mandatory reporting of product positives. That has existed for an extended period of time.
Where we did not have that obligation on the part of industry was for the environmental testing, and that speaks more to this issue of prevention and how we get early detection and early assessment to determine there's not a persistent infection in the plant. So what did change with the new directives last fall was making the environmental testing mandatory, in terms of all positive results, to supplement what we were already getting on the end product.
