A number of councils across South and West Wales have withdrawn certain meat products from their schools and care homes today after a sample of an approved supplier's meat tested positive for horsemeat.
Newport company Welsh Bros Foods confirmed a sample of its frozen minced beef has 'potentially tested positive' for above 1% horsemeat.
The company says it is 'deeply shocked' but believes it is an isolated incident. Further tests will now be undertaken.
The news broke as ministers and officials were reassuring AMs about their handling of the horsemeat scandal.
