At the start of the week, 167 cases of illness had been reported in 17 states. States where new cases have been reported are Florida, Georgia, Missouri, New York, Tennessee and Vermont.
The Center for Disease Control and Prevention on Thursday acknowledged that the salmonella may have been a contributing factor in the cancer-caused death of a 67-year-old Texas man.
Nearly 25 people have been hospitalized during the outbreak, caused by a relatively rare strain of salmonella known as Saintpaul.
The federal agency said the latest known illness struck on June 1 and urged consumers to avoid eating or handling raw red plum, raw red Roma, and raw red round tomatoes unless they come from a state or country deemed safe by government food inspectors. The list includes 28 states and seven countries.
Tomatoes should not be consumed unless they were grown in specific states or countries that has gotten clearance from the FDA. These farms were not harvesting or selling when the outbreak began that sickened many people.
Grape tomatoes, cherry tomatoes and tomatoes sold with the vine still attached are also considered safe by the FDA. Nineteen Florida counties are safe to ship their tomatoes again but some top-producing counties, such as Collier and Dade, still are under investigation.
Most Florida growers are shipping again. The Florida agriculture department has issued certificates verifying the origin for an estimated several thousand loads, state officials said.
