Researchers develop technologies to devour food pathogens

coli, is found in the intestines of warm-blooded animals, it does not naturally contaminate most produce. Therefore, following more stringent sanitary policies, as well as practicing better manure and water management, can go a long way to help prevent future outbreaks, Linton said.

E. coli is especially problematic because it only takes as few as 10 cells to infect humans. Other pathogens, like salmonella, need thousands or millions of cells to cause infection.

As of Sept. 26, 183 cases of illness were reported due to spinach contamination with a virulent strain of E. coli.

"What is happening is unacceptable," Linton said.

Bhunia's technology is further described in an article published this summer in the Journal of Biomedical Optics. Linton and Morgan have been working with chlorine dioxide for years, and have several published studies, one of which appeared in the Journal of Food Protection in 2004.
