Food Standard Officials have today issued some robust guidelines to public institutions amid the horsemeat contamination scandal.
They have made it clear that suppliers of meat to schools and hospitals are to be included in a UK-wide system of checks.
The companies that supply public bodies will be subjected to new "verification and validation" tests. Schools and hospitals have been told to require their suppliers undertake tests.
The new document has gone to schools, prisons, hospitals and the armed forces.
The key advice is they must "seek assurances" from all their meat suppliers.
They have also been told to take a hard line and "reject or ... withhold stock" from any firm that they are not fully satisfied can give the right guarantees.
