"There were 16 significant or unusual multistate outbreaks of foodborne illnesses in the U.S. in 2011, with five of them involving fresh produce, according to the Centers for Disease Control and Prevention’s annual year in review.
Fresh produce involved was: romaine lettuce, cantaloupes (two outbreaks), whole papayas and alfalfa/spicy sprouts. Two outbreaks were related to nuts. One involvined Turkish pine nuts, the other was linked to hazelnuts.
“Our list of multistate foodborne outbreaks on the list for 2011 is not comprehensive — it just lists certain ones that may be unusual in terms of size, pathogen, etc., and whether we took a leading role in the outbreak,” leader of CDC’s outbreak response team Casey Barton Behravesh said Jan. 12."
