FDA Closes Romaine Lettuce Salmonella Investigation: 43 Cases, Product Past Shelf Life When Source Was Confirmed
The U.S. Food and Drug Administration (FDA) has updated its table of foodborne illness outbreak investigations: the investigation into the Salmonella I 4,[5],12:i:- outbreak, reference #1402, is now closed. The outbreak sickened 43 confirmed patients, and epidemiologic and traceback investigations by the Centers for Disease Control and Prevention (CDC), FDA and state and local partners identified romaine lettuce as the likely source of illnesses. FDA says the outbreak has ended and there is no risk to consumers.
FDA collected and analyzed environmental samples as part of the investigation, but all samples were reported as negative for Salmonella. By the time investigators had enough information to confirm romaine lettuce as the source, the products were past their shelf life and no longer available for sale. FDA's closure notice did not name a brand or grower for the lettuce involved.
In the same update, FDA also closed its investigation into a Salmonella Newport outbreak, reference #1403, which had 119 cases and no identified source. A Cyclospora outbreak, reference #1392, was adjusted from 241 to 175 cases and closed, with parsley identified as its likely source, and a separated incident, reference #1396 with 66 cases, was also closed without a confirmed source. An active Salmonella Javiana investigation, reference #1424, rose from 59 to 65 cases, and FDA has initiated traceback.
