That's the word on the street, er, Yahoo News, anyway:

MADRID, Spain - Spain plans to impose stricter rules on production of a staple of the national diet and increasingly popular export -- ham from free-range pigs that feed on acorns and herbs -- in order to weed out stable-bound impostors, a newspaper said Sunday.

The salt-cured ham, like Italian prosciutto but darker and chewier, is produced around Spain from a breed called the Iberian pig, a dark, long-legged creature with a pointy snout.

But because of ambiguous laws, the techniques used in many provinces do not comply with traditional standards for the ham to receive a certificate of quality, much like the 'denomination of origin' used in the wine industry, El Pais said.

Avast ye, ye swine!
