As of August 1, 2014 a total of 19 persons infected with the outbreak strain of Shiga toxin-producing Escherichia coli O121 (STEC O121) were reported from six states. The number of ill persons identified in each state was as follows: California (1), Idaho (3), Michigan (1), Montana (2), Utah (1), and Washington (11).
44% of ill persons were hospitalized. No ill persons developed hemolytic uremic syndrome (HUS), and no deaths were reported.
Epidemiology and traceback investigations conducted by local, state, and federal officials indicated that contaminated raw clover sprouts produced by Evergreen Fresh Sprouts, LLC of Idaho are the likely source of this outbreak.
The FDA conducted an inspection of Evergreen Fresh Sprouts’ facility on May 22-23, 2014; May 27-30, 2014; and June 6, 2014. During the inspection, FDA investigators observed a number of unsanitary conditions, including condensate and irrigation water dripping from rusty valves; a rusty and corroded mung bean room watering system; tennis rackets that had scratches, chips, and frayed plastic” used to scoop mung bean sprouts; a pitchfork with corroded metal being used to transfer mung bean sprouts; and a squeegee with visible corroded metal and non-treated wood being used to agitate mung bean sprouts inside a soak vat.
Also, according to CDC, from April 12 to July 5, 2011, a total of 25 persons infected with the outbreak strain of Salmonella Enteritidis have been reported from five states. Results of the investigation indicate a link to eating alfalfa sprouts and spicy sprouts manufactured by Evergreen Fresh Sprouts. On July 1, 2011, Evergreen Fresh Sprouts LLC of Moyie Springs, Idaho, announced a recall of specific lots of alfalfa sprouts and spicy sprouts because these products have the potential to be contaminated with Salmonella.
