London looks to get ahead of disease threat

LONDON (Reuters) - If someone's stomach is churning and cramping after eating a burger or club sandwich from a pop-up vendor at the London Olympics, Brian McCloskey plans to be among the first to hear about it.

As the man in charge of disease surveillance during the Games, he says the greatest risk will be food poisoning from people eating street snacks in warm weather, failing to wash their hands and using the same toilets as millions of others.
