18 AAC 31.985 - Potentially Hazardous Food

(1) a food of animal origin that is raw or heat-treated, a food of plant origin that is heat-treated or consists of raw seed sprouts, cut melons, or garlic-in-oil mixtures that are not modified in a way that results in mixtures that do not support pathogenic microorganism growth or toxin formation; and

(2) except for a food for which the department has granted a variance under 18 AAC 31.930, a food that, because of the interaction of its water activity and pH values, is designated as PA in Table L or M of this section.

(1) a hard-boiled egg with shell intact that has been air-cooled, or an egg with shell intact that is not hard-boiled, but has been pasteurized to destroy all viable Salmonellae;

(2) food in an unopened hermetically sealed container that is commercially processed to achieve and maintain commercial sterility under conditions of non-refrigerated storage and distribution;

(3) food that, because of its pH or water activity value, or interaction of water activity and pH values, is designated as a non-potentially hazardous food in Table L or M of this section; or

(4) food that is designated as PA in Table L or M of this section, if the department has granted a variance under 18 AAC 31.930.
