Bacteria are microscopically small, single-cell creatures that have a primitive structure which is a body sealed by a relatively solid-cell membrane.  Ozone oxidises the cells,  through inhibiting and blocking the operation of the enzymatic control system. A sufficient amount of ozone breaks through the cell membrane, and destroys the bacteria.

Viruses are small, independent particles, built of crystals and macromolecules, Unlike bacteria, they multiply only within the host cell. They transform protein of the host cell into proteins of their own. Ozone destroys viruses by diffusing through the protein coat into the nucleic acid core, resulting in damage of the viral RNA.  At higher concentrations, ozone destroys the capsid, or exterior protein shell by oxidation so DNA (deoxyribonucleic acid), or RNA (ribonucleic acid) structures of the microorganism are affected.

It is important to note that Ozone machines generate concentrated gas at the source of the machine and as the gas disperses it breaks down . However it is equally important to note just how much ozone is required to kill the most resilient viruses and bacteria

As example

Hepatitis A virus  99.5% reduction at 0.25 mg/l for 2-seconds in a phosphate buffer
0.25mg/1 is equal to 0.25-PPM

Ecoli 99.5% reduction at 0.25 mg/l for 2-seconds in a phosphate buffer
0.25mg/1 is equal to 0.25-PPM

The illustration below shows how ozone attacks bacteria and quick the kill is. This applies to viruses both non enveloped and enveloped  and has equal kill times.

  Bacteria  Ozone approaching bacteria

  Ozone ( O3 ) bonds with the organic compounds in the cell wall and starts to destroy the integrity of the cell wall       

  In milliseconds, the kill is complete, and Ozone continues to oxidise the bacteria and any released organics.

Ozone gas is the most effective way to kill viruses and bacteria in food without leaving harmful residues
