There has been a voluntary recall of romaine lettuce that spans across 19 states due to concerns over possible E-coli contamination.  Tanimura & Antle, which is based out of California, is recalling its Field Fresh Wrapped Single Head Romaine.  So, if you purchased that specific type, you need to return it to the grocery store you bought it from or toss it out.  Stores in New Jersey, New York and Pennsylvania are all dealing with this recall, as well as several provinces in Canada.  Puerto Rico is also dealing with the recall.
