Two of the inpatients developed a type of renal insufficiency (hemolytic uremic syndrome) known to be associated with this particular bacterial species, E. coli O157: H7.
Bacteria typically produce a toxin within a few days of swallowing the beetle, causing symptoms such as bloody diarrhea, vomiting and stomach cramps. Usually, this dissolves within a week, but sometimes it can get worse.
Maryland health officials are waiting to see if E. coli in a unopened Ready Pac chicken Caesar salad package is genetically related to the causative bacteria in a patient's home. Patients in Maryland reported eating this particular brand, while others in other states did not. CDC recommends that people not eat or sell this product on October 31st with the "Best" date.
Bonduelle Fresh Americas said on Wednesday that the researched salads were Ready Pac Foods Bistro Chicken Grown with Antibiotic-Free Caesar Salad. 255406963, UPC # 7774527249. The company said it was sold only at Sam's Club.
The company has tested all green-leaf plants and said they are not positive, and said we continue to work with all regulatory agencies to monitor the source of this contamination as soon as possible to reduce potential impacts on consumers. Test results for E. coli O157: H7 over time period.
The CDC is investigating whether other products are linked to the outbreak.
