The 1st tests from a north German farm suspected of being the source
of an _E. coli_ [O104:H4] outbreak are negative, officials say. Of 40 samples from the farm being examined, they said 23 tested negative.
Officials had said earlier that bean sprouts produced at the farm in Uelzen, south of Hamburg, were the most likely cause of the outbreak. The outbreak, which began 3 weeks ago and is concentrated in Hamburg, has left 22 people dead. Initially, German officials had pointed to Spanish cucumbers as the probable cause of the illness.
The moderator notes that just because the ones being tested are negative, it doesn’t rule out the farm as the source of the outbreak. Perhaps all the contaminated sprouts are gone, and if it was something wrong at the farm (contamination of the water by sewage or something similar), it may have resolved itself. Nevertheless, after the false start with the Spanish cucumbers, it would certainly be nice to get some kind of confirmation. Apparently the tests on the remaining 17 samples are still pending so it remains to be seen if there will be any proven connection, but it’s looking less likely. If they don’t find anything definitive, officials are going to have even more egg on their faces.
While the human cases seem to be slowing down, this is going to be bad if the source can’t be identified–and that gets more difficult to do every day that passes.
