Authorities believe they have found the source of the European E. coli outbreak that has killed 22 people: a farm in northern Germany that produces bean sprouts. Authorities say the farm is the “likely source” and closed it; however, they are awaiting the results of testing. The farm grows a wide variety of vegetable sprouts including those from adzuki, alfalfa, broccoli, peas, lentils and mung beans. The farm's manager says he "can’t understand how the farm would be the source, since the plants aren’t fertilized." German authorities originally pointed toward Spain as the source of the outbreak.
