So far, the CDC has been unable to pinpoint the source of the outbreak but health officials believe it was caused by contaminated tomatoes or other fresh vegetables. The CDC is continuing its investigation but has stated "there is little evidence of continuing risk to the public."
The states involved in the outbreak were Arkansas, Connecticut, Georgia, Indian, Kentucky, Maine, Massachusetts, Michigan, Minnesota, North Carolina, New Hampshire, Ohio, Pennsylvania, Rhode Island, Tennessee, Virginia, Vermont, Washington, and Wisconsin.
This outbreak of salmonella is not associated with the outbreak of E. coli-tainted spinach in September that sickened almost 190 people and is confirmed to have killed an elderly Wisconsin woman.
