Three outbreaks of Salmonella infections associated
with eating Roma tomatoes were detected in the United States and Canada in
the summer of 2004. In one multistate U.S. outbreak during June 25–July
18, multiple Salmonella serotypes were isolated,
and cases were associated with exposure to Roma tomatoes from multiple locations
of a chain delicatessen. Each of the other two outbreaks was characterized
by a single Salmonella serotype: Braenderup in one
multistate outbreak and Javiana in an outbreak in Canada. In the three outbreaks,
561 outbreak-related illnesses from 18 states and one province in Canada were
identified. This report describes the subsequent investigations by public
health and food safety agencies. Although a single tomato-packing house in
Florida was common to all three outbreaks, other growers or packers also might
have supplied contaminated Roma tomatoes that resulted in some of the illnesses.
Environmental investigations are continuing. Because current knowledge of
mechanisms of tomato contamination and methods of eradication of Salmonella in fruit is inadequate to ensure produce safety, further
research should be a priority for the agricultural industry, food safety agencies,
and the public health community.
