the week as the seven nuclear reactors that have been shuttered after the Japan nuclear emergency are widely expected to stay closed for good. Peakload prices for delivery in 2012 in bilateral over-the-counter trade rose around EUR2 a megawatt-hour to between EUR73.15/MWh and EUR73.35/MWh. On the Germany-based European Energy Exchange baseload for delivery in 2012 rose to EUR60.05/MWh, up around 1% on the day from EUR59.46/MWh. The 2012 baseload contract has gained nearly 13% since the March 11 earthquake and tsunami that triggered the nuclear disaster in Japan. In 2010, nuclear reactors accounted for around 23% of Germany's power production, making them the second-largest contributor to overall output behind lignite-fired power plants. The government said earlier Monday that it will end the use of nuclear energy by 2022 at the very latest. The country's seven oldest nucleardelivered to stores in Austria by German companies. "If anything is found to be left over, it will be tested and taken off the market," Austrian Health Ministry spokesman Fabian Fusseis said. While two German tourists have tested positive for enterohaemorrhagic E.coli, also known as EHEC, no so-called homegrown cases have been reported, he added. In Germany, where the death toll rose to 11 on Monday, officials said even though they know that Spanish cucumbers tainted with EHEC have carried the bacteria, they still have not been able to determine the exact source. "We have found the so-called EHEC pathogens on cucumbers, but that does not mean that they are responsible for the whole outbreak," Andreas Hensel, president of Germany's Federal Institute for Risk Assessment, said on ZDF television. Spanish Health Minister Leire Pajin, noting that no Spanish cases have been reported, urged Germany to speed up its probe and establish proof of what has caused the outbreak. Germany's allegations "create alarm and affect the producers of a country without any evidence," she said. In Poland, officials said Monday that a woman has been hospitalized in serious condition after returning from a trip to the northern German city of Hamburg, where at least 467 cases of intestinal infection have been recorded. On Sunday, authorities said those included 91 cases of the more severe hemolytic uremic syndrome, but the officials noted on Monday that the number of new diarrhea cases was declining. HUS is a rare complication arising from infection associated with the E. coli bacterium. Czech officials said tests on 120 potentially tainted Spanish cucumbers pulled off shelves on Sunday are expected to be concluded in two days. No illnesses have been reported. In Italy, meanwhile, the country's paramilitary Carabinieri tainted food squad has been on the lookout since Saturday for any contaminated cucumbers, checking imports from Spain, the Netherlands and other European countries. So far, lab analyses have come back negative, and no cases of food poisoning have been report
