E. coli outbreak in Europe

The source of an E. coli outbreak in Europe that has killed 22 people and sickened more than 2,200 is still not known. German authorities at first blamed it on cucumbers grown in Spain, causing outrage among Spanish farmers. They are claiming they lost tens of millions of dollars due to a slump in demand. Tests showed that Spanish cucumbers did not contain the dangerous strain. Bean sprouts from a farm in Germany are now being tested, though the first tests did not find the contamination. Cases have shown up in at least 10 countries and have left more than 600 in intensive care.(30 photos total)

The number of people sickened by a mysterious killer bacteria grew, two weeks after the outbreak in Germany, while fears over tainted vegetables hit European farmers hard. Scientists and health officials say they have identified the E. coli bacteria responsible for the outbreak, which has mainly affected northern Germany, but are unable to say what caused it or who was responsible.

The source of the killer bacteria remained elusive on June 6 after Germany announced that initial tests on suspected organic sprouts had proved negative and the outbreak's death toll grew to 23.

The sign reads, "Benalmadena with the Andalusian farmers". (Jon Nazca/Reuters)

The ministry of consumer affairs said a nationwide special warning had been issued, adding that investigations were underway to track the origin of contaminated vegetables which have been ordered withdrawn from the market.

A farmer throws out his cucumber crop after it was impossible to sell in El Ejido, near Almeria in southeastern Spain, on May 31, 2011. Spain said on Monday there was no proof that cucumbers from its growers had caused an outbreak of E.coli in Germany that had killed 14 people and that it would be demanding to know why its farmers had been blamed. An E. coli outbreak linked to contaminated cucumbers that has also made more than 300 seriously ill in Germany has spread to other north European countries and is expected to worsen in the coming week. The E. coli pathogen has been identified on cucumbers imported from Spain but it is unclear if they were contaminated there, during transport or in Germany. (Fabian Bimmer/Reuters)

armer Tobias Haack drives a tractor over 100,00 heads of romaine, iceberg, and 10 other types of lettuce in order to mulch them back into the ground at one of his fields on June 4, 2011 near Hamburg, Germany. Vegetable farmers in northern Germany are facing a crisis as public reaction to the current enterohemorrhagic E. coli, also known as the EHEC bacteria, outbreak has brought vegetable sales to a near halt. Haack says he usually sells 1,000 crates of lettuce a day, though currently he is selling about 40. "I hope they don't leave us hanging," he says of the German government, and considers current discussions of low-interest loans to stricken farmers unhelpful. He says if the crisis continues he will face severe financial problems within two to three weeks. (Sean Gallup/Getty Images)
