Dutch find different E. coli, pull beet sprouts (AP)

AMSTERDAM � Dutch authorities recalled red beet sprouts from three countries Thursday after samples were found to be contaminated with a strain of E. coli bacteria that was apparently less dangerous than the one causing Europe's deadly E. coli crisis.

German health officials, meanwhile, reported that three more people died of the ailment Thursday, raising the toll to 29 in less than six weeks.

The Dutch Food Safety Authority said laboratories were still trying to identify the Dutch strain of E. coli, but said there have been no immediate reports of serious illness from it.

Still, the agency said it was definitely not the same E. coli strain that killed 29 people, sickened 2,900 others and left hundreds with serious complications, most of them in Germany. The cause of that outbreak has so far eluded German investigators.

Only one Dutch grower, a company called Hamu, was found with contaminated beets, and other produce grown on its farms were cleared of suspicion, said Esther Filon, a spokeswoman for the Dutch regulation agency.

"It's not the same as in Germany. You can become ill, but as far as we know at this moment, it is not lethal," she told The Associated Press.

She said the authorities were trying to trace all shipments from the grower.

The agency said Hamu, based in the town of Kerkdriel, 44 miles (70 kilometers) southeast of Amsterdam, had exported beet sprouts to Belgium as well as selling them on the Dutch and German markets.

There are hundreds of E. coli bacteria strains in nature, but only a few are deadly to humans and the bacteria is more commonly known as a source of food poisoning or severe stomach problems.

People naturally carry several harmless E. coli strains in their intestines and the bacteria is also widely found in cows, sheep and other mammals. Strains which are harmless to animals can sometimes be lethal for humans. Experts worry about E. coli's constant evolution, which may result in dangerous mutations for humans.

The European Union informed the Netherlands late Wednesday that contaminated beet sprouts had been found in Germany, and tests in the Netherlands confirmed it.

Harald Wychel of the National Institute for Public Health said authorities are still investigating whether anyone has fallen ill from the Dutch strain.

In Berlin, the Robert Koch Institute said the rate of new illnesses was declining in the deadly E. coli outbreak. It said 2,808 people have been sickened in Germany, 722 of whom are suffering from a serious complication that can cause kidney failure. But it was not clear whether the epidemic was waning, or people were just successfully shunning fruit and vegetables.

The World Health Organization says 97 others have fallen sick in 12 other European countries, as well as three in the United States.

Germany's Lower Saxony state health ministry said two more people died after being infected � a 20-year-old woman and an 68-year-old man.

At least five people were hospitalized following a family gathering for a 70th birthday late last month south of Hannover, and investigators were probing the catering firm for possible leads to the outbreak's source, the state ministry said.

European Union farmers say they have been losing up to euro417 million ($611 million) a week as ripe produce rots in fields and warehouses. The EU pledged Wednesday it would offer farmers compensation of up to euro210 million ($306 million) for the E. coli losses.

Russia and Saudi Arabia have issued a blanket ban on vegetable imports from the European Union.

Spanish farmers have been among the hardest hit, after authorities in Hamburg issued a warning that Spanish cucumbers could be the source of the outbreak. Further tests showed that while the Spanish vegetables did carry E. coli, it was not the strain behind the outbreak.

Spain's Secretary of State for European Affairs, Diego Lopez Garrido, said the compensation being offered by the EU is not enough and blasted the Russian ban on all EU vegetables as "inappropriate." Russia is a huge market for EU produce.

Study finds why smokers gain weight when they quit (AP)

WASHINGTON � Scientists say they've finally discovered why smokers tend to gain some weight when they kick the habit.

It turns out that nicotine can rev up brain cells that normally signal people to stop eating when they're full, researchers report in Friday's edition of the journal Science.

The weight connection isn't huge: On average, quitters gain less than 10 pounds. Still, it's a worry that many smokers cite when asked why they don't try to quit. Now the question is whether the discovery might lead to better treatments to help them quit without worrying about weight.

Yale University associate research scientist Yann Mineur stumbled onto the connection while studying a nicotine-related substance in mice � and the animals suddenly started eating less.

Nicotine hooks onto a variety of receptors, or docking sites, on the surface of cells. That's how it triggers addiction in one part of the brain.

But when it comes to weight, the Yale research found that both nicotine and the related drug cytisine were activating a different receptor than the one involved in addiction. This one is located on a small set of neurons in the hypothalamus, a region that regulates appetite.

When they gave nicotine to mice without that cellular pathway, it didn't help them lose weight like it did normal mice.

Smoking causes cancer, heart attacks and a host of other ailments so worry about modest weight gain shouldn't deter someone from quitting. But smokers who do have that concern should try nicotine-based smoking-cessation treatments, said study senior author Marina Picciotto, a Yale professor of psychiatry and neurobiology.

The other drug used in the mouse experiments, cytisine, is sold in Eastern Europe for smoking cessation but not in the U.S., and she'd like to see if there's data on the weight of smokers abroad who've used it.

Developing a drug to target only these specific receptors would be difficult, she cautions, because they're also involved in the body's stress responses in ways that could lead to such side effects as high blood pressure.

Dutch find different E. coli on beet sprouts (AP)

AMSTERDAM � Authorities say they have halted sales of beet sprouts from a Dutch grower after some were found to be contaminated with a strain of E. coli bacteria that is different from the one causing Europe's deadly E. coli crisis.

The Dutch Food Safety Authority said the European Union informed it late Wednesday that illness-causing Dutch vegetables had been found in Germany. It said beet sprout samples inspected in the Netherlands also confirmed instances of E. coli contamination.

But the agency said it was not the same E. coli strain that has killed 27 people, sickened 2,900 others and left hundreds with serious omplications, most of them in Germany.

The name of the producer was not released.

THIS IS A BREAKING NEWS UPDATE. Check back soon for further information. AP's earlier story is below.

BERLIN (AP) � Germany's national disease control center says another person has died in the European E. coli outbreak and 160 more people have been reported ill, but that the rate of new sicknesses is continuing to decline.

The Robert Koch Institute said Thursday that 2,808 people, 722 of whom are suffering from a serious complication that can cause kidney failure, have now been reported sickened in Germany, the country at the epicenter of the E. coli outbreak whose origin has not yet been found.

The World Health Organization says 97 others have fallen sick in 12 other European countries, as well as three in the United States.

A total of 27 people have died � 26 in Germany and one in Sweden.

Though the number of those sickened is still rising, the Koch institute says the new cases being reported have been dropping for several days.
