Recently I was doing some research on the use of ozone on E.Coli O157 H7 Reduction. I found more information than I expected, so, I though I would share it with the world.

The reason for the research is due to a paper we are writing on some testing we recently performed on using ozone gas for E.coli reduction on ground beef. The research was successful and I will share the data and paper soon. I was looking for references for this paper, I found more than I expected.

E.coli O157:H7 is one of the main strains of bacterium that causes food borne and waterborne illness. Although most strains of E.coli are harmless and live in the intestines of healthy humans and animals, this strain produces a powerful toxin and can cause severe illness.

Here are the titles and links to the papers I found. I will be getting the full abstracts up on our website soon.  Each of these papers covers the use of ozone as an antimicrobial agent for use on E.coli O157:H7

Utilization of Ozone for the Decontamination of Small Fruits

Effectiveness of ozone for inactivation of Escherichia coli and Bacillus cereus in pistachios

Application of Ozone for Inactivation of Escherichia Coli O157:H7 on Inoculated Alfalfa Sprouts

Efficacy of Ozone Against Escherichia coli O157:H7 on Apples

Efficacy of aqueous ozone for the decontamination of Escherichia coli O157:H7 and Salmonella on raspberries and strawberries.

Inactivation of Escherichia coli O157:H7 and Natural Microbiota on Spinach Leaves Using Gaseous Ozone during Vacuum Cooling and Simulated Transportation

Decontamination of Escherichia coli O157:H7 and Salmonella enterica on blueberries using ozone and pulsed UV-light.

And finally, the U.S. EPA has a page specifically answering your questions regarding E.coli O157:H7
