Untreated canal water at a cucumber farm in Florida has been identified as one of the sources of the outbreak.
The outbreak involves 7 different Salmonella serotypes, 3 of which were found in samples from boxes used to ship poultry from hatcheries.
Four people required hospitalization, but there were no confirmed deaths in the outbreak.
Of the 12 people interviewed, 7 (58%) reported contact with a bearded dragon before getting sick.
The CDC and FDA are also investigating a second similar Salmonella outbreak that has sickened 184 people in 24 states.
Fifty-four people have been hospitalized, with no deaths reported.
The outbreak has sickened 109 people in 29 states, according to the CDC.
The illnesses were caused by Campylobacter, Salmonella, E coli, or Listeria monocytogenes.
The products, which appear pre-browned and cooked, are often cooked from a frozen state, which increases the chance that the raw chicken component may not reach a safe internal temperature.
Salmonella was detected in 52% of commercial farm samples and in 19% of backyard farm samples.
