Thank you, Madam Chair. Thank you for your question.
For us as well, the challenge is to continue to be aware of new scientific methods and all the international developments in this and other areas.
For us, I think it is that challenge of making sure we keep up with the science. At this moment, we're very comfortable that we've combed the world, that we have gathered the scientific experts and have built the linkages with our international partners. We are very much focused on the current state-of-the-art science. But we also know that just as nature will change and throw us new challenges, science will continue to develop very rapidly.
I think for us it's never a matter of a point in time. It's never a matter of just one disease--listeria versus salmonella or E. coli or others. It is really to keep on top of the totality of the challenges in the scientific world. That is, I think, what our experts do.
Madam Chair, perhaps I will ask Dr. Farber if he could expand on that.
