Can Chlorine Dioxide be used with Organic Foods?

ClorDiSys is occasionally asked if chlorine dioxide can be used in organic foods or in organic processing facilities. The short answer is yes.  More specifically, according to 7 CFR part 205, SUBCHAPTER M—ORGANIC FOODS PRODUCTION ACT PROVISIONS, the use of chlorine dioxide is allowed, but it comes with some restrictions. Its use is permitted for Livestock Management Tools and Production Aids, for Processing Sanitizers and Cleaners, and for Crop Management Tools and Production Aids. The common restriction across all three applications is the residual chlorine levels in any final rinse water or water in direct contact with food products or animals. The water cannot exceed the maximum residual disinfectant limit under the Safe Drinking Water Act (0.8 mg/L or 800 ppb). Reference the label of the product you are using to establish proper use corresponding with such restrictions. Visit the websites below for additional information to see if your organic operation qualifies for chlorine dioxide usage.
