What do alfalfa sprouts, frozen rodents and pot pies have in common?

You guessed it–Salmonella I 4,[5],12:i:- (that’s pronounced four five twelve eye minus).  The recent Salmonella I 4,[5],12:i:- outbreak linked to sprouts served at Jimmy John’s restaurants is the third I 4,[5],12:i:- outbreak in the last two years.

Here are the summaries from the Centers for Disease Control and Prevention on the outbreaks:

After three outbreaks, don’t you think that Salmonella I 4,[5],12:i:- deserves a proper serotype name?  Hmmm, how does Salmonella Marler sound?
