NEW YORK (Reuters):

Video of rats scampering across a New York City restaurant floor may have disturbed viewers worldwide but some experts say the rodents are less dangerous than other creatures drawn to restaurants - humans.

The video broadcast on television a week ago showed rats running wild at a KFC/Taco Bell restaurant just one day after the outlet had passed a city Health Department inspection.

It took a bite out of the share price of parent company Yum Brands Inc. and forced a city Health Department shake-up that removed the inspector who conducted the review from duty and led to 13 more restaurant closures last Thursday.
