Tests confirming that a brand of lasagne contained up to 100 percent horsemeat sparked a wider food scare in Britain on Friday, with authorities ordering urgent tests on all beef products. The Food Standards Agency said criminal activity was likely to blame as consumers grappled with an escalating horsemeat scandal on the shelves of major British supermarkets. Food company Findus tested 18 of its beef lasagne products manufactured by French supplier Comigel and found 11 meals containing between 60 percent and 100 percent horsemeat, the FSA said.

FSA chief executive Catherine Brown told the BBC it was "highly likely there has been criminal and fraudulent activity involved."

* Tests ordered after horse meat found in beef * Horse meat not harmful, but supply chain questioned Feb 7 (Reuters) - Britain's horse meat scandal has prompted the Food Standards Agency to demand a more stringent meat testing programme from UK's retailers. The agency has demanded that food retailers and suppliers test all beef products such as burgers, meatballs and lasagne and present their findings to the agency by February 15.

As a Hindu who does not eat beef but craves other meat, Tashny Sukumaran discovered her new passion for pork burgers through her native Malaysia's vibrant food-blogging, or "flogging", scene. The Muslim-majority country's mainstream media shy away from references to pork and other foods objectionable to Islam, but blogs have helped spark a burger boom in a nation with sizeable ethnic Chinese and Indian communities. "I kept reading about pork burgers on 'flogs' but have never seen much in newspapers, I guess because it's non-halal," said Sukumaran, 22.
