Tests have found horsemeat in school meals, hospital food and restaurant dishes in Britain, spreading the scandal over adulterated meat beyond frozen supermarket products.

Results were coming Friday after food safety officials ordered supermarkets and suppliers to test all processed meals labeled as beef for traces of horsemeat.

Whitbread PLC, Britain's largest hotel and restaurant company, said horsemeat had been found in lasagna and burgers served at its Premier Inn hotels and Brewers Fayre restaurant chain.

Officials also said horsemeat was present in cottage pies delivered to 47 schools in Lancashire county, northern England.

Horse also has turned up in hospital meals in Northern Ireland. David Bingham, of the health service's Business Services Organization, said the meals, from a supplier in the Republic of Ireland, had been withdrawn.
