WASHINGTON (AP) - Three common ingredients in salsa are now the suspects in a salmonella outbreak that has hit 42 states.
It's the nation's largest foodborne outbreak in at least a decade.
But seven weeks into their investigation, federal health officials aren't shortening the list of potential culprits. Instead, they're adding to it.
Now jalapeno pepper producers are being investigated along with tomato distributors, even fresh cilantro is under suspicion.
Geography offers a potential clue.
Most of the sick are in the Southwest.
