DEL Ozone Food Safety Systems are Performance Validated  

It is critical (and required by law) for food safety sanitation or disinfection treatment systems to effectively kill pathogens in all food processing environments. For 30 years, DEL Ozone has partnered with or commissioned accredited third-party testing and validation organizations, as well as university food scientists, to verify that specific ozone applications achieve the intended outcome. Testing and Validation are Core Values at DEL.
 

Ozone Outperforms Traditional Disinfection Treatments

Ozone is an effective antimicrobial oxidizer that can be safely applied as a disinfectant/sanitizer wherever traditional chemical or thermal sanitation methods are used. It is used in either as a gas, or dissolved in water and used as an aqueous solution. Ozone is validated to kill all known food and human pathogens, as well as safety-validated for facility workers and facility environments.

Ozone has been third-party validated by scientists since 1906 for a multitude of pathogens in an array of applications.  However, almost all validations are concerning the same pathogens that are considered critical to food safety. These include (but are not limited to): E. coli, Listeria, Salmonella, Staphylococcus, Campylobacter, Pseudomonas, Cryptosporidium, Bacillus, Aspergillus, Norovirus and Adenovirus.

Studies have proven that ozone is more efficient and has a higher oxidation potential than most traditional disinfectant/sanitizers (e.g. chlorine, hydrogen peroxide, peroxyacetic acid and chlorine dioxide), and its use eliminates the need to rotate sanitizers because contaminants cannot build a tolerance to ozone. Ozone is non-corrosive to facility surfaces, does not negatively affect the organoleptic qualities of food and leaves no residual (never needs a final fresh water rinse).
