WAIT! You Must Know This Before Eating Romaine Again in NH

According to a news report from WMUR, it's okay to eat Romaine lettuce again!  Hooray!  It's the only type of lettuce I really like.  HOWEVER, the report goes on to say that they haven't found the source of the original contamination!!?  What?  Wait.

I don't know about you, but if the FDA doesn't know how the e-coli got to the lettuce to begin with, how are they going to prevent it from happening again?

Look, everybody makes mistakes and I generally don't think it's the worst thing in the world, but I'm in radio.  If I make a mistake, no one is POTENTIALLY GOING TO DIE because I played a song twice in one hour, ya know what I'm sayin'?  Having said that, if mistakes are made, I make it my mission to get to the bottom of it.  It bugs the be-geezus out of me until I find out what the cause was.  I cannot imagine that I would give the 'ALL CLEAR' if I was in charge of the romaine lettuce factory.
