Food Safety said it had issued an immediate recall of the cucumbers that also applies to tomatoes and eggplants. The agency said that some of the vegetables may have been sold and it is urging consumers to throw them away. The Czech Agriculture and Food Inspection Authority said cucumbers from a contaminated shipment also went to Hungary and Luxembourg. There were no immediate reports of illness there. The cucumbers transited Germany, where at least nine people have died and almost 300 have been sickened by hemolytic uremic syndrome. HUS is a rare complication arising from infection associated with the E. coli bacterium. Almost a dozen people with HUS have been hospitalized in Sweden in the past two weeks after travel to Germany. In Denmark, eight people are hospitalized with E.coli infection that could be linked to the outbreak. A spokesman for the European Union said Sunday that two greenhouses in Spain that were identified as the source of the contaminated cucumbers had ceased activies. The water and soil there are being analyzed to see whether they were the problem or the contamination occured elsewhere, said Frederic Vincent, the spokesman. The results of the tests are exptected Tuesday or to better understand the relationship between computer and alcohol use, the researchers say. "Children are being exposed to computers and the Internet at younger ages," said study researcher Jennifer Epstein, a public health researcher at Weill Cornell Medical College in New York. "For this reason it's important that parents are actively involved in monitoring their children's computer usage, as well as alcohol use.” The study is published in the journal Addictive Behaviors. Teenage drinking Epstein and colleagues surveyed more than 200 adolescents between the ages of 13 and 17 about their online activity and alcohol use. Teens who drank alcohol in the last month spent, on average, 16 hours online per week excluding schoolwork activities. Those who didn't drink alcohol in the last month spent 12.7 hours online per week excluding schoolwork. No link was found between playing online video games or shopping online and drinking. It's important that parents realize their children face enticements online that may encourage underage drinking, the researchers say. Pros and cons of the Internet The study adds to a growing body of research that has found both pros and cons to teen Internet use. A recent report from the American Academy of Pediatrics described a new phenomenon known as "Facebook depression," in which children and teenagers spend too much time on social networking sites, then develop symptoms of depression. And other studies have linked Internet use in general to an increased risk of depression and loneliness among teens. But Internet use can benefit adolescents as well. In addition to helping with homework, studies have found online activities help teens maintain ties with friends. And one study found those who di
