A New Zealand manuka honey producer who has offered to test what he calls a “rip-off” of manuka honey says fake versions of the health product cost the industry millions.

And he says educating consumers is the key to fighting the misleading claims on the labels of these shonky products.

Cornwall beekeepers have imported manuka plants from New Zealand to produce their own version of medicinal manuka honey which they are selling at £5 ($13) a teaspoonful.
