As the beef crisis deepens in Europe, butchers in the Athens area have banned the sale of beef after demanding meat and feed undergo stricter checks for mad cow disease, Carlton TV reports. The ban covers butcher shops and meat stalls in Athens and surrounding areas home to close to half of Greece's nearly 11 million people. It does not effect supermarkets or other parts of the country. A statement from the Athens area butchers' union demanded that EU health officials enact 'measures to protect the health of the consumer and not the economic interests of the powerful.' The decision was made after health inspectors confiscated 50 tons of livestock feed suspected of containing banned animal products.
