We've had risk assessments performed by Harvard University, which said that even if we did have a small number of cases in this country that the likelihood of it spreading or getting into any kind of human health problem is very, very small.

Great Britain had a much different situation than we do and did here in the United States, in that they had literally thousands of infected animals with human health risks. Their infectivity in this disease happened before very much was known about it.

I have to say that in this particular cow that we're dealing with, those parts of the cow were removed, and so we don't think there's any risk or very negligible risk to human health with this particular incident.

But the fact of the matter is that all scientific evidence would show, based upon what we know about this disease, that muscle cuts - that is, the meat of the animal itself - should not cause any risk to human health.

I think it's important that, as a matter of course, the brain and spinal column were removed from this cow, and that would be the material that would cause concern in terms of human health. And therefore we're confident in the safety of the food supply.
