Bean_Sprouts.jpgAP reports a few moments ago that local German organic vegetable sprouts have been linked epidemiologically to the E. coli O104:H4 outbreak that has killed 30 people and sickened nearly 3,000 – nearly 750 with Hemolytic Uremic Syndrome. Reinhard Burger, president of the Robert Koch Institute, Germany’s national disease control center, said the pattern of the outbreak had produced enough evidence to draw that conclusion even though no tests of sprouts from an organic farm in Lower Saxony had come back positive for the E. coli strain behind the outbreak. Warnings have been lifted against lettuce, tomatoes and cucumbers.

“In this way, it was possible to narrow down epidemiologically the cause of the outbreak of the illness to the consumption of sprouts,” Burger said at a press conference with the heads of Germany’s Federal Institute for Risk Assessment and Federal Office for Consumer Protection:

“It is the sprouts.” 

Do not forget the 12,680 sickened in 1996 in Sakai, Japan from radish sprouts. Fukushima H, Hashizume T, Morita Y, Tanaka J, Azuma K, Mizumoto Y, Kaneno M, Matsuura MO, Konma K, and Kitani T. 1999.

From the CDC: Sprouts Not Healthy Food for Everyone

Children, the elderly, and persons whose immune systems are not functioning well should not eat raw sprouts, because current treatments of seeds and sprouts cannot get rid of all bacteria present.

Persons who are at high risk for complications from foodborne illness should probably not eat raw sprouts, according to an article in the current issue of Emerging Infectious Diseases, CDC’s peer-reviewed journal, which tracks new and reemerging infectious diseases worldwide.

Although sprouts are often considered a “health food,” the warm, humid conditions needed for growing sprouts from seeds are also ideal for bacteria to flourish. Salmonella, E. coli, and other bacteria can grow to high levels without affecting the appearance of the sprouts.

Researchers have treated both seeds and sprouts with heat or washed them in solutions of chlorine, alcohol, and other chemicals. Some of these disinfectants reduced the levels of bacteria, but a potential hazard remained, especially for persons with weak immune systems. High temperatures that would kill the bacteria on the seeds would also keep them from sprouting. Until an effective way is found to prevent illness from sprouts, they should be eaten with caution, if at all.

    I’ve been saying for a while, that all spout containers should have a label that says “Eat at your own risk”

  • doc raymond

    Does anyone know if this is the same sprouting operation where 2, maybe now 3, workers were ill with the same bacteria? And might that not support human contamination of the sprouts and/or facitlity as opposed to contaminated water or seeds coming into the facility?

  • I think it depends if the worker or workers were the index case or cases.
    German health officials investigating a large Escherichia coli outbreak released new findings today that cast more suspicion on bean sprouts, though tests on a cucumber found in a sick family’s compost reportedly yielded the outbreak strain.
    Gert Hahne, a spokesman for Lower Saxony state’s Consumer Protection Ministry, said 18 people who became will with the enterohemorrhagic E coli (EHEC) O104:H4 outbreak strain got sick after eating sprouts from an organic farm that were served in their company cafeteria in Cuxhaven.
    The latest findings push the number of illness clusters to seven, which include about 100 people who got sick after eating at four company cafeterias and three restaurants that are known to have received sprouts from the farm.
    On Jun 5, health officials in Lower Saxony state tentatively linked bean sprouts grown at an organic farm in the northern part of the country to the massive EHEC outbreak based on initial tests. But more extensive tests conducted so far on samples from the facility haven’t turned up the outbreak strain.
    Also, Hahne said three women who worked at the farm and helped package the sprouts were sick with diarrhea during the first half of May, and one of the women had a confirmed EHEC infection. He said that a sick worker could have contaminated the sprouts or could have been sickened by the sprouts on the farm.

    It’s still not too late to change the story once again, this time to poltergeist.
    Could mean a lucrative book deal and movie rights if poltergeist is the cause…no box office draw for grubby old bean sprouts and diarrheic greenhouse workers. Could use a portion of the book & movie proceeds to pay off Spanish organic E. coli-slathered cucumber producers!

  • Carl Custer

    Classic question:
    Did the workers bring the bug to the sprouting environment or did they get it from the sprouting environment?
    Anyone checking seeds for external or internal bugs?
    Where is the ruminate connection?
    “Cherchez la vache”

  • Gabrielle Meunier

    Poltergeist? That is hilarious. Perhaps all sprouts should be labeled that they are “potentially contaminated by Poltergeists. Eat at your own risk.” I know it is not a laughing matter at all, but Doc you made me laugh.

  • Pain is one that now not in the first page for the news.
    It seems that they do not like the good news of Spain.
    Been they have never infected cucumbers of Spain
    I hope that the compensation is so clay as the caused damage, to the economy and the image…
