Ozone's powerful disinfection capability has made it very useful in many areas of food processing and packaging. As concerns about the health effects of chlorine treatment by-products rise, ozone is gaining an important role in many food applications, including:

• Fruit and vegetable disinfection
• Poultry chiller water treatment
• Meat storage
• Spice and nut disinfection
• Seafood disinfection
• Food storage to extend shelf-life and prevent pest infestation (grains, potatoes etc)
• Ozonated ice for extending shelf-life of seafood, and produce
• Wheat tempering with ozonated water to reduce microbial count in flour
• Rinse fruits and vegetables for neutralization of residual
pesticides and fertilizers, and to kill surface
bacteria and virus.
• Rinse and soak meat and poultry in ozonated water to kill salmonella, E. coli and other harmful microbes, as well as to neutralize residual hormones. Preservation time is increased 2 to 5 times.
