Ozone not only destroys the bacterial cell, but it does it without leaving a residual effect.
As a comparison based on 99.99% of bacterial concentration being killed and time taken, ozone is:
Furthermore, ozone is at least ten times stronger than chlorine as a disinfectant. Chlorine reacts with meat forming highly toxic and carcinogenic compounds called THMs or tri-halomethanes – rendering the meat to a lesser quality product. THMs have also been implicated as carcinogens related to kidney, bladder and colon cancers. Chlorine also results in the production of chloroform, carbon tetrachloride and chloromethane. On the other hand, ozone does not leave any trace of residual product after its oxidative reaction.
