Summary of United States Regulation - Hypochlorous Acid
FDA Food Contact Notification - Hypochlorous Acid at up to 60 ppm for Produce, Fish & Seafood, Meat and Poultry Sanitation
Hypochlorous acid may may be used in processing facilities at up to 60 ppm for use in process water or ice which comes into contact with food as a spray, wash, rinse, dip, chiller water, and scalding water for whole or cut meat and poultry, including carcasses, parts, trim, and organs; in process water, ice, or brine used for washing, rinsing, or cooling of processed and pre-formed meat and poultry products as defined in 21 CFR 170.3(n)(29) and 21 CFR 170.3(n)(34), respectively; in process water or ice for washing, rinsing or cooling fruits, vegetables, whole or cut fish and seafood; and in process water for washing or rinsing shell eggs.
FDA Guidance for Industry: Guide to Minimize Microbial Food Safety Hazards of Fresh-cut Fruits and Vegetables
The antimicrobial activity of a chlorine-based disinfectant depends on the amount of hypochlorous acid (also called “free chlorine”) present in the water. The amount of hypochlorous acid in the water depends upon the pH of the water, the amount of organic material in the water, and, to some extent, the temperature of the water. If the amount of hypochlorous acid is not maintained when the amount of organic material increases, the antimicrobial agent may lose effectiveness in maintaining water quality. If a fresh-cut processor uses a chlorine containing compound as a disinfectant, we recommend that the processor monitor the processing water for free chlorine or hypochlorous acid concentrations.

EPA: Food-Contact Surface Sanitizing Solutions - Allowance of Hypochlorous Acid at up to 200 ppm
The following chemical substances when used as ingredients in an antimicrobial pesticide formulation may be applied to food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils. When ready for use, the end-use concentration of all hypochlorous acid chemicals in the solution is not to exceed
200 ppm determined as total available chlorine.

Food Contact Notification
Hypochlorous acid is cleared by the FDA for use on meat, poultry, fish & seafood, fruits & vegetables and shell eggs as a no-rinse sanitizer.
FCN is a Food Contact Notification (FCN) from the FDA for using electrolytically generated hypochlorous acid as an antimicrobial agent in an aqueous solution in the production and preparation of whole or cut meat and poultry; processed and preformed meat and poultry; fish and seafood; fruits and vegetables; and shell eggs.

USDA - National Organic Program
This memorandum clarifies that electrolyzed water (hypochlorous acid) is a type of chlorine material that is allowed in organic production and handling.
On June 9, 2014, the National Organic Program (NOP) published a policy memorandum (PM 14-3) on the status of electrolyzed water under the USDA organic regulations at 7 CFR Part 205. Following the release of PM 14-3, stakeholders provided additional technical and regulatory information on electrolyzed water to the NOP. Chlorine materials are allowed to be used in organic production and handling. The National Organic Program (NOP) Handbook includes guidance… READ MORE
