Taco Bell, the US-based fast food company, has withdrawn its taco beef products from sale in British and Spanish outlets after finding some beef contained more than 10% horse DNA. The move came as Birds Eye confirmed that two ready meals it removed from supermarket shelves as a precaution last week have proved to have "low levels" of horse DNA.
