I understand that when it comes to public health, consensus building isn't necessarily the model we want to look at.
I'm interested in your use of words, because I was going to raise the issue about what one sees in science, what's called the precautionary principle, with which not everybody is familiar. I'll ask Dr. McKeown to look at that.
You talked about it earlier and I thought you were leading to a precautionary principle, where one doesn't wait until we absolutely know it's either bean sprouts, tomatoes, or red peppers. We talked about the public issue rather than worrying about individual producers or suppliers of a product to make sure that we actually get that absolutely right. It doesn't mean to say we stop looking to find out what the product is that's contaminated.
So perhaps, Dr. McKeown, you could enlighten us about that. Should we be using that as a more frequent model, or is it something we should be ignoring?
