Latest version.
  •   (1) Chemical sanitizers, including chemical sanitizing solutions generated on-site, and other chemical antimicrobials applied to food-contact surfaces shall:

      (a) Meet requirements specified in 40 CFR 180.940 and 40 CFR 180.2020; and

      (b) Be used in accordance with the EPA-registered label use instructions.

      (2) Chlorine sanitizer solutions shall have a minimum concentration and temperature:

      (a) of 25 to 49 mg/L at 120 degrees F,

      (i) with an associated contact time of 10 seconds;

      (b) of 50 to 99 mg/L at 100 degrees F, pH of 10 or less, or 75 degrees F, pH or 8 or less,

      (i) with an associated contact time of 7 seconds; or

      (c) of 100 mg/L at 55 degrees F,

      (i) with an associated contact time of 10 seconds.

      (3) Iodine sanitizing solutions shall have a:

      (a) Minimum temperature of 68 degrees F;

      (b) pH of 5.0 or less of a pH no higher than the level for which the manufacturer specifies the solution is effective;

      (c) Concentration between 12.5 mg/L and 25 mg/L; and

      (d) Contact time of at least 30 seconds.

      (4) Quaternary ammonium compound solutions shall:

      (a) Have a minimum temperature of 75 degrees F;

      (b) Have a concentration as indicated by the manufacturer's use directions included in the labeling;

      (c) Be used only in water with 500 mg/L hardness or less or in water having a hardness no greater than specified by the EPA-registered label use instructions; and

      (d) Have a contact time of at least 30 seconds.

      (5) Hot water sanitization, without the use of chemicals, shall be accomplished by:

      (a) Manual immersion for at least 30 seconds in water held at a minimum temperature of 171 degrees F or higher;

      (b) Being cycled through equipment which:

      (i) the temperature of the sanitizing rinse as it enters the manifold may not be more than 194 degrees F or less than 165 degrees F for stationary racks or 180 degrees F for all other machines; and

      (ii) achieves a utensil surface temperature of 160 degrees F as measured by an irreversible registering temperature indicator.
