Reducing Salmonella detection times

The winners of the U.S. Food and Drug Administration’s first ever Food Safety Challenge managed to reduce the 24- to 48-hour Salmonella detection waiting time to between 30 minutes and three hours, according to a story on Refinery 29. The winning team from Purdue University uses small filters, and the runner-up team from Pronucleotein uses portable, DNA-based technology. The challenge sought to find faster methods for detecting Salmonella in minimally processed fresh produce.
