News Summary: Burger King drops tainted supplier

HAVE IT YOUR WAY: Burger King has stopped buying beef from an Irish meat processor whose patties were found to contain traces of horsemeat, potentially causing a Whopper shortage in restaurants in the U.K. and Ireland.

WHERE'S THE BEEF?: The supplier, Silvercrest, last week shut down its production line and recalled 10 million burgers from supermarket shelves in Britain and Ireland after horse DNA was found in some beef products.

NEW WORRY: Burger King says its patties are made from 100 percent beef, and officials say the horsemeat poses no risk to human health, but the episode has raised food security worries.
