The lettuce in question contains a single head of romaine in a package with the UPC number 0-27918-20314-9.
No one has become sick from eating the lettuce as of now, according to the FDA.
A total of 3,396 cartons of potentially affected product were distributed to the 20 states. The product was shipped in cases packed in either 12, 15, 18 or 24 heads per case, according to the FDA.
E. coli O157:H7 causes a diarrheal illness, including the symptom of bloody stools. Although most healthy adults can recover within a week, some people can develop a form of kidney failure called Hemolytic Uremic Syndrome (HUS).
