Maryland Department of Health investigate E. coli cluster of illnesses linked to romaine lettuce

The Maryland Department of Health is investigating a cluster of Escherichia coli O157:H7 (E. coli O157) illnesses in seven patients in Maryland. All seven consumers reported eating Ready Pac Bistro® Bowl Chicken Caesar Salad purchased from various Sam’s Club locations in Maryland. There has been one hospitalization and no deaths associated with these cases.  The same salads are also sold at many other retailers. One unopened salad that had been purchased by one of the patients identified in the outbreak was tested, and the presence of E. coli O157 was detected in the salad’s romaine lettuce. There was no recall of the product because, by the time the investigation was completed,  the products identified are already significantly past their use-by dates. @ https://health.maryland.gov/newsroom/Pages/Maryland-Department-of-Health-investigating-E--coli-cluster.aspx
