We have a presence in China. They may not necessarily visit the field directly. We have done audits. We have dispatched Canadian auditors to China in response to verification of activities of how the inspection system is operated in China, to validate the regulatory controls, to regulate how they do their testing programs, to follow up in terms of the certification processes.
As I say, we do have a full-time presence in certain regions of the world currently that collaborate with our partners, whether it's the U.S. or the EU. When they conduct audits they share their information of compliance with us. We adjust our border measures accordingly.
Behind that we also have, as we've talked about, the ability to do residue monitoring at the border or post-entry. If we have a suspicion, if information comes to our attention, either through sources such as INFOSAN or if there is an international recall of a product, we have the authority to stop at the border, to hold and detain and do further testing either at the border or inland, to validate that there is in fact no contamination of the product coming in.
