Section 18 AAC 34.070 - Sanitizing(a) Except as provided in (b) of this section, the concentration level of each chemical or compound used in sanitizing must comply with the manufacturer's instructions for the sanitizing use indicated in the instructions. The processor shall verify the concentration is correct with a test kit, test strip, or other device.(b) A processor may use the following sanitizing and testing methods:(1) immersion for at least 30 seconds in clean water at a temperature of 170º Fahrenheit or above;(2) immersion for at least 30 seconds in one of the following clean sanitizing solutions at a temperature of 75º Fahrenheit or above: (A) 50 ppm of available chlorine as hypchlorite;(B) 12.5 - 25 ppm available iodine with a pH no higher than 5.0; or(C) quaternary ammonium compound at a concentration specified by the manufacturer and included on the label, with a pH no less than 6.0 and water hardness no greater than 500 ppm, following the manufacturer's instructions regarding use of a final rinse after sanitization;(3) sprayed- or wiped-on (A) chlorine solution containing at least 100 ppm of available chlorine as hypochlorite; or(B) iodine, quaternary ammonium compound, or another sanitizer solution approved by the department; the sanitizer solution must be used at a concentration specified by the manufacturer for air drying; or(4) sprayed or wiped on chlorine solution containing at least 200 ppm available chlorine as hypochlorite, iodine, or quaternary ammonium compound at a concentration specified by the manufacturer for a contact time of at least 20 minutes before a final rinse.(c) Table 1 of this subsection represents the ratio of water to chlorine that will give 50 ppm of free chlorine residual: TABLE 1
WATER TO CHLORINE RATIO
Amounts of chlorine are shown in tablespoons required to give 50 ppm of free chlorine residual. For 100 ppm of free chlorine residual double the amounts below. For 200 ppm of free chlorine residual four times the amounts below.
