When we look at allowing the use of a pesticide, our act is very clear. We have to look at human health, and we look at human health from a number of perspectives. So yes, we look at whether the residues in the foods consumed present a concern. That's dealt with in international trade through the establishment of maximum residue limits.
We also have to look at occupational health and safety issues and bystander health and safety issues. We also have to look at environmental issues. You can have, and have lived through, incidents where we've been concerned about the environmental risk of a product or the occupational health exposure of a product but were not concerned about the dietary exposure of a product, because the nature of the risk is different.
