Ozone in production surface sanitation:
Ozone can be used in food processing, distribution and retail centers as a surface sanitation on food contact surfaces. This is referenced in CRF 205.605, however it is made clear in the following document:
USDA wording from: The USDA National Organic Program Requirements for Food Retailers and Distribution Centers
The regulations identify some chlorine materials that may be used to sanitize food-contact surfaces, including calcium hypochlorite, chlorine dioxide, and sodium hypochlorite; hydrogen peroxide and ozone are also permitted. See 7 C.F.R. 205.605.
