Chlorine Dioxide & Food Contact Surfaces

As a residue free process, chlorine dioxide gas is safe for use on food contact surfaces. It is even on the National Organic Program's List of Approved and Prohibited Substances as an approved substance for use on organic foods. ClorDiSys has also been approved by the U.S. Food and Drug Administration’s (FDA) for antimicrobial fruit and vegetable rinses in both the gaseous and liquid states with more approvals in the works now.

Chlorine dioxide’s use is allowed under FDA jurisdiction as given in the following regulations: 
  • 21 CFR PART 173 -- SECONDARY DIRECT FOOD ADDITIVES PERMITTED IN FOOD FOR HUMAN CONSUMPTION
  • 21 CFR PART 178 -- INDIRECT FOOD ADDITIVES: ADJUVANTS, PRODUCTION AIDS, AND SANITIZERS
  • 21 CFR PART 137 -- CEREAL FLOURS AND RELATED PRODUCTS 
  • GRAS Notice 062, GRAS Notice 161

The above incorporate a variety of industry applications including chlorine dioxide’s use as an antimicrobial agent in water used in both poultry processing and for washing fruits and vegetables. It is also allowed as a sanitizing solution on food-processing equipment and utensils, to bleach whole wheat flour, and can be used in packaging materials for fresh fruits, vegetables, meats, poultry and seafood. 

Food Contact Notices (FCN) are required for any new food contact substance and uses which do not fall under the scope of the regulations above. A FCN is effective for the manufacturer, the Food Contact Substance (FCS), and the conditions of use identified in the notification and not effective for a similar or identical substance produced or prepared by another manufacturer. ClorDiSys has the following food contact notices in place: 
  • FCN 1665 – Chlorine dioxide as an antimicrobial agent used to fumigate fruits and vegetables, including raw agricultural commodities. 
  • FCN 1634 – Chlorine dioxide as an antimicrobial agent in water used in poultry processing and to wash fruits and vegetables, including raw agricultural commodities (RAC). 
  • FCN 1421 – Chlorine dioxide as an antimicrobial agent in air to treat fruits and vegetables. 
  • FCN 1400 – Chlorine dioxide as an antimicrobial agent in water used in poultry processing and to wash fruits and vegetables that are not raw agricultural commodities.
