I may ask the experts who are here with me today to help with that, but it can vary tremendously. The evidence we have to this point, based on the one positive sample, is that we are looking at a very, very low rate of infestation on those Alberta farms, but keep in mind that these are very small organisms and very large fields, in some cases. This is how sampling works. If you find a positive, it doesn't mean it's the only one in the field. It's indicative of the presence, albeit at a very low level.
