02-Feb-2009 (17 years 4 months 12 days ago)If only one of the parents is the named breed, then the product must be clearly labelled as being from a cross-breed. The advice comes from Lacors - the Local Authorities Coordinators of Regulatory Services.
This means that if a piece of meat is, for instance, labelled ‘Gloucestershire Old Spot’ or ‘Berkshire’ consumers will know they are buying pork from pure-bred animals.
