Watch out for bagged lettuce:
"SPRINGFIELD, Ill. – Dr. Damon T. Arnold, Director for the Illinois Department of Public Health is warning Illinoisans about iceberg lettuce distributed by Aunt Mid’s Produce Company. The Illinois Department of Public Health (IDPH) has identified Aunt Mid’s Produce Company as the distributor of iceberg lettuce consumed by six Illinois residents during late August to mid-September who have been diagnosed with E coli 0157."
Of course, I don't know about you, but I've never seen this band in stores, and from the description of the 'industrial sized' bags they are probably destined for Food service. The outbreaks have been mostly in Michigan.
Nothing so far linking this to supermarket lettuce, but all the same I'm glad I get my lettuce at the farmer's market.
