(c) time/temperature control for safety food does not include:
(i) An air-cooled hard-boiled egg with shell intact, or an egg with shell intact that is not hard boiled, but has been pasteurized to destroy all viable Salmonellae;
(ii) A food in an unopened hermetically sealed container that is commercially processed to achieve and maintain commercial sterility under conditions of nonrefrigerated storage and distribution;
(iii) A food that because of its pH or Aw value, or interaction of Aw and pH values, is designated as a non-tcs food in Table A or B of this subsection;
(iv) A food that is designated as product assessment required (PA) in Table A or B of this subsection and has undergone a product assessment showing that the growth or toxin formation of pathogenic microorganisms that are reasonably likely to occur in that food is precluded due to:
(A) Intrinsic factors including added or natural characteristics of the food such as preservatives, antimicrobials, humectants, acidulants or nutrients;
(B) Extrinsic factors including environmental or operational factors that affect the food such as packaging, modified atmosphere such as reduced oxygen packaging, shelf life and use, or temperature range of storage and use; or
(C) A combination of intrinsic and extrinsic factors; or
(v) A food that does not support the growth or toxic formation of pathogenic microorganisms in accordance with (c)(i) through (iv) of this subsection even though the FOOD might contain a pathogenic microorganism or chemical or physical contaminant at a level sufficient to cause illness or injury.
