I can't speak for the entire industry but speaking for Richardson, I can say it's rare. I think that's the appropriate description.
Our system is based on taking representative samples at loading, at the end of the loading spout as it goes onto the vessel. It's at the very last point of contact in Canada with the exportable commodity. That is then analyzed. It's third party. It's Canadian Grain Commission certificate final. Then, if a phytosanitary certificate is required, those samples are submitted directly to the CFIA for their expert analysis and a phytosanitary certificate is issued.
I can't remember a situation in canola, in China, or in what one would traditionally consider to be our most quality conscious destinations like Japan, where we've had a problem that wasn't detected at point of load. I can't even remember one we've had at point of load. This is a very unique, unusual circumstance.
