"The holy grail of fresh-cut produce is finding a wash step that's going to be more effective than chlorine at reaching those bacteria that chlorine can't quite reach," said David Gombas, senior vice president of food safety and technology at the United Fresh Produce Association, a trade group.
The place uses ozone-sanitation technology, which its managers say is more effective than chlorine.
Fresh Express said that its new cleaning mixture was 750 times as effective as chlorine in killing bacteria suspended in wash water.
It is also at least nine times as effective as chlorine in killing bacteria that has become attached to the leaves of produce.
Equivalent Effective Stratospheric Chlorine (EESC) is a parameter designed to estimate that component of ozone variability in the stratosphere that is driven by changes in the long-term abundances of Ozone Depleting Substances (ODSs) in the atmosphere.

Orue et al. (2013) reported that extracts from oregano and lime are as effective as chlorine based disinfectants for decontamination of Salmonella, Shigella and Escherichia coli O157 H7 on leafy vegetables.
But we haven't used it because we have traditional weapons which are more effective than chlorine".
Unbeknownst to scientists and water utilities at the time, says Johnnie Hemphill, interim director for public affairs at DCWASA, pH adjustments are not as effective without chlorine.
The laser annealing treatment was found to be effective in promoting Chlorine diffusion and improving the optical and morphological properties of CdTe thin film devices.
