Only lamb and cattle that have been born and reared in Wales and slaughtered and processed at approved abattoirs and cutting plants will be able to use the description that the EU has awarded Welsh Lamb and Welsh Beef – Protected Geographical Indication (PGI).
HCC has therefore created a list of abattoirs and cutting plants authorised to slaughter and process these brands, to make businesses certify they are buying the right products.
Those who sell false products from unlisted abattoirs under these logos could potentially face prosecution.
HCC chief executive Gwyn Howells said: "The Welsh Lamb and Welsh Beef brands are seen as trustworthy by the public because of their quality and traceability and it is important that businesses do not mislead their customers about where their meat is from.
"Both Welsh Lamb and Welsh Beef are protected by the EU, and HCC will continue to work with enforcement authorities to ensure consumer confidence in the brands is not eroded by fraudulent activity," he added.
