Thank you for your question.
The demonstration projects that we're trying to facilitate right now have basically two elements.
One element is that they would measure in the environment, where the vaccine is being used, the reduction of E. coli. Again, it's naturally coming out of the cattle; it can naturally get into aquifers, it's on their hide, and it can be carried into packing plants. We would be measuring the actual reduction of the E. coli that could potentially be at risk of being exposed to humans.
The other element we're looking at is really more of a trade issue, in that we believe there are customers, both internationally and domestically, who, if they knew there were supply chains of cattle available that had a further risk reduction procedure done to them, might get a premium, or it might get them preferential supplier status. That again would be a favourable signal to the farming community that something like this could help them in their marketing.
