Microbiologist Ching-Hsing Liao of the USDA Agricultural Research Service has developed a potential new way to clean produce. The method utilizes beneficial bacteria that can prevent the growth of pathogens. He found that produce that had been dipped into solutions containing the good bacteria were protected from Salmonella and E. coli. Further research is being prepared to find which strains of bacteria are most effective. Full story: USDA
