Welsh Ministers must work with local authorities to launch a thorough programme of testing of food to establish where horsemeat has been sold as beef.
Local authorities already have the power to intervene and prosecute a food business, which tries to pass off a product as organic, when it is not.
The law needs to come down equally hard on anyone who has knowingly deceived the public by selling a product, which is not as described.
Consumers must have confidence that the food they buy is safe and is accurately labelled so they can make an informed choice.
Approved supplier Welsh Bros Foods confirmed a sample of its frozen minced beef has 'potentially tested positive' for above 1% horsemeat.
The Welsh Government says it is working with the police to ensure allegations of horse meat at a plant in west Wales are dealt with.
