Section 18.31.424. Sanitizing.

	(a)  The operator of a food establishment shall ensure that food-contact surfaces are sanitized before use after washing and rinsing as follows:  
		(1) for manual warewashing that uses hot water to sanitize, immersion for at least 30 seconds in clean water at a temperature of 170_  F or above;  
		(2) for mechanical warewashing that uses hot water to sanitize,  
			(A) by being cycled through equipment that is designed, constructed, installed, and maintained as specified in 18 AAC 31.412;  
			(B) by achieving a utensil surface temperature of 160_ F or above at the end of the sanitizing cycle as measured by an irreversible registering temperature indicator; and  
			(C) by maintaining the final rinse temperature of the fresh hot water sanitizing rinse as it enters the manifold at   
				(i) not more than 194_ F, except high pressure and temperature systems with wand-type, hand-held, spraying devices used for the in-place cleaning and sanitizing of equipment; and   
				(ii) not less than the temperature specified in Table H in 18 AAC 31.423;  
		(3) for manual or mechanical warewashing that uses chemicals to sanitize, including the application of sanitizing chemicals by immersion, manual swabbing, brushing, or pressure spraying methods using one of the sanitizing solutions specified in Table I of this section, or another approved exposure time used in relationship with a combination of temperature, concentration, and pH that yields sanitization.
