We have to do whatever we can to ensure that no child dies of diarrhea.

I think hygiene is so important.

We're going to do everything possible to make sure that food safety is always paramount, and that we work with the industry as aggressively as we can to make sure that we're paying attention to the food-safety issues.

Hygiene is important. That's one of my failings. So I'm always being called on that.

We continue to be vigilant.

I think it's important to watch out for our environment and to be careful.

In the week before a race, I try to stay away from germ areas. I keep disinfectant wipes in my bag for when I have to use a supermarket trolley or something like that.

The health of the people is of supreme importance. All measures looking to their protection against the spread of contagious diseases and to the increase of our sanitary knowledge for such purposes deserve attention of Congress.

Those who store, package, and sell the food we serve our families have a responsibility to maintain basic standards of cleanliness in their facilities.

I think it's always important to be vigilant of what you're doing and aware of your surroundings.
