The FDA says they are now investigating cilantro, serrano peppers and jalapenos as they continue to search for the cause of the salmonella outbreak.

The number of salmonella cases keeps growing. The government says the record outbreak has now sickened 943 people, putting at least 130 in hospitals.

Tomatoes are still the leading suspect, but other types of fresh produce are being tested as well.

Investigators aren't saying exactly what vegetables are getting tracked but that they're looking at items commonly served with fresh tomatoes.

The Food and Drug Administration is looking at several possibilities. Maybe tomatoes and other produce shared a common packing or shipping site where both might become contaminated. Or multiple foods might have been tainted while being grown on adjoining farms or with common water sources.

Officials say some patients have told the Centers for Disease Control and Prevention they ate raw tomatoes in fresh salsa and guacamole.
