According to Der Spiegel, German authorities have traced the lethal outbreak of e-coli to a single organic farm in Germany:

Health authorities in Germany have finally been able to show that the pathogens which caused the deadly EHEC outbreak came from sprouts at an organic farm in the Uelzen district. According to SPIEGEL ONLINE information, the breakthrough was made by scientists in the state of North Rhine-Westphalia. Final verification, however, is still pending.

As of Friday it remained unclear how the dangerous bacteria came to be present at the farm.

The death toll so far is 29 people.

Kate at Small Dead Animals quips:

"One German organic farm has killed twice as many people as the Fukushima nuclear disaster and the Gulf Oil spill combined. Crickets."
