Using recombinant-based in vivo expression technology (RIVET), University of Florida researchers have discovered that tomato variety and maturity may influence the growth and prevalence of Salmonella enterica bacteria within the fruit. The findings, published August 31 in Public Library of Science (PLoS) ONE, suggest researchers may be able to develop tomato cultivars more resistant to Salmonella enterica contamination.

Also, by monitoring tomato ripeness, it may be possible to reduce the fruit’s susceptibility to contamination during and after harvest.

These findings support the concept that salmonella contamination is not solely caused by substandard handling procedures during and after harvest.
