I'd agree with Dr. Smyth. The first test is whether the product has been safety assessed in the market. To qualify as an LLP, it would have to meet that test first. Second, a risk assessment ensures that your regulators are able to demonstrate, based on the data that they have, full application of the technology provided that the product is safe, and it's an application in Canada. So you have a safety measure there. After that, I think a threshold level is mostly about commercial tolerances, and the operations, the grain-handling system. The lower you make that level, the more challenging and expensive it is for a grain-handling system to deal with it.
You are trying to apply a threshold when you know the product is safe, and then from a commercial point of view, what is realistic in terms of managing that product.
