The bacterium that has killed more than a dozen Europeans, sickened nearly 2,000 more and raised international alarms would be legal if it were found on meat or poultry in the United States.
If the bacterium were to contaminate fruits or vegetables grown here, there would be no way to prevent an outbreak, because farmers and processors are not required to test for the pathogen before the food heads to supermarkets.
“If somehow this strain got into that same environment and spread rapidly, it would represent a major disaster in terms of the U.S. food industry and risk to humans,” said J. Glenn Morris, a former official with the U.S. Department of Agriculture who directs the Emerging Pathogens Institute at the University of Florida. “The regulatory framework is a couple of steps behind.”
The strain that has emerged in Europe is a particularly virulent version of E. coli 0104 and, in the outbreak that began in early May, has been linked to more than 1,600 illnesses and 18 deaths. About 500 people — an unusually large percentage of those who have been sickened — have developed a life-threatening kidney complication known as hemolytic uremic syndrome, for which there is no treatment.
