The number of Americans affected by salmonella-contaminated tomatoes has reached 756 in 43 different states. The source of the contamination continues to be a mystery. No deaths have been attributed to the illness, the US Food and Drug Administration (FDA) said in a statement. At least 95 people have been hospitalized, according to CDC.

It was estimated a number of 22,600 potential illnesses in the tomato outbreak.

“However, a man in his sixties who died in Texas from cancer had an infection with the outbreak strain of Salmonella Saintpaul at the time of his death. The infection may have contributed to his death,” the CDC said, according to Reuters.

The majority of the infections have occurred in Texas, with more than 300 people becoming ill.  

The FDA continues to warn consumers to avoid raw red plum, red Roma and round red tomatoes which are linked to the contamination.

Salmonella Saintpaul infections cause fever, diarrhea, nausea, vomiting and abdominal pain. The CDS estimates about 400 cases of Saintpaul infections in humans each year. More people are expected to become ill because the outbreak is still on, health officials said. Symptoms appear within 36 hours of exposure, and usually last four to seven days. The prevention of Salmonella as a food illness involves effective sanitizing of food contact surfaces.
