At least 35 people in 11 states have been infected with E.coli O157:H7, according to the CDC, and the FDA is investigating a likely link to these infections and chopped romaine lettuce from Yuma, Arizona. The reported illnesses occurred between March 22 and March 31, and 93% of the 28 people interviewed reported eating romaine lettuce (mainly from a restaurant) during the week that they became ill.
The FDA and CDC are advising consumers to ask restaurants and other food service establishments where they source their romaine lettuce from and to avoid any that came from Yuma, Arizona. In addition, they should not buy or eat it if they cannot confirm the source.
“Retailers, restaurants, and other food service operators should not sell or serve any chopped romaine lettuce from the winter growing areas in Yuma, Arizona. If you cannot determine the source of your chopped romaine lettuce, do not sell or serve it. The FDA currently does not have information to indicate that whole-head romaine lettuce or hearts of romaine have contributed to this outbreak.” – FDA
The agencies will continue to investigate this outbreak. FDA emphasized that this outbreak is not related to a multistate outbreak that occurred last November to December involving leafy greens, as those infections had a different DNA fingerprint of the E. coli O157:H7 bacteria.
