tomatoesFox News reports that contaminated fresh tomatoes served in restaurants were the cause of a recent salmonella outbreak that sickened dozens of people in 21 states, health officials said Friday.

The outbreak, now over, sickened at least 183 people, according to the Centers for Disease Control and Prevention. There were no reports of deaths, although 22 people were hospitalized. Interviews with victims, including detailed surveys of what they had eaten and where before falling sick, led investigators to suspect restaurant tomatoes as the cause.

"We have identified tomatoes eaten in restaurants as the cause of this outbreak. We don’t have any information that a name or a certain type of restaurant is involved. As far as we can tell, it’s across the board,"said Dr. Christopher Braden, a foodborne outbreak and surveillance expert with the CDC.
