French-German E. coli link seen in sprouted seeds

Dutch and British health officials advised people to avoid raw salad shoots and seeds on Monday after scientists linked an outbreak of E.coli in France to a highly toxic one in Germany that has sickened more than 3,900 people and killed 47.

A British health safety expert said it was very unlikely to be pure coincidence that sprouted salad seeds have been identified as the probable source of both outbreaks.

Two more people were hospitalized in Bordeaux on Monday, taking the total now being treated for infection with the E.coli bacteria to nine, French authorities said.

One of those admitted was a returning patient who had been allowed home after being hospitalized last week. The other was a new case who was taken to hospital with bloody diarrhea.

Earlier in the day, another patient was moved out of intensive care, while the condition of a 78-year-old woman was said to have changed to stable from serious. The other five patients are said to be stable.

French authorities say at least two of those affected have been found to have the same rare strain that has infected thousands in Germany.

"We've got a new emergent infection that has rarely been described before and it's cropped up twice in the same food product," said Paul Hunter, an E. coli expert and professor of public health at Britain's University of East Anglia. "That cannot be coincidence."

Britain's Food Standards Agency (FSA) said sprouted seeds such as alfalfa, mung beans -- usually known as beansprouts -- and fenugreek should only be eaten if they have been cooked thoroughly "until steaming hot throughout."

"They should not be eaten raw," it said in a statement.

'Same contamination'
Initial investigations into the outbreak of E. coli in France have suggested a possible link to sprouting seeds from a British company, Thompson & Morgan.

The firm said on Monday it was withdrawing a number of varieties of seeds from sale and advised people not to eat or grow them. However, it was not yet recalling any of its products.

"Thompson & Morgan is keen to reassure its customers that so far no substantive link has yet been established between the consumption of sprouted seeds and the outbreak of E. coli," it said in a statement.

Health authorities in Germany have linked the epidemic there to contaminated bean sprouts and shoots from a German organic farm sold to consumers and restaurants for eating in salads.

Latest data from the European Center for Disease Prevention and Control, which monitors disease in the region, show that at least 3,919 people have been infected in the outbreak.

"Although this has not been proven, it's almost certainly going to be the case that seeds in both the French and German outbreaks were probably contaminated at the same place â€" either where the seeds were grown or very soon afterwards," said Hunter.

The FSA said that to date, no cases of food poisoning have been reported in Britain linked to the outbreak in France.

The Dutch ministry of health said it was advising people not to eat raw fenugreek, mustard seeds and other sprouts. Nine cases of E. coli with direct links to the German outbreak were recorded in the Netherlands but Dutch officials said so far no-one else has become ill.

E.coli bacteria thrive in nutrient-rich environments like the guts of humans or cows. This strain â€" known as STEC O104:H4 â€" has been found to be particularly sticky, making it likely to be able to cling on to leaves, seeds and other foodstuffs.

Hunter, who noted that E.coli outbreaks linked to sprouts are a fairly regular event in Europe and America with two or three a year, said the germs can survive for several months on seeds prior to sprouting and are almost impossible to detect.

"I know a lot of people like raw sprouting seeds, but if you want them then you've got to decide whether or not you're prepared to take the risk," he said.
