(i) Microorganisms capable of reproducing in the food under normal nonrefrigerated conditions of storage and distribution; and

(ii) Viable microorganisms, including spores, of public health significance; or

(b) By the control of water activity and the application of heat, which renders the food free of microorganisms capable of reproducing in the food under normal nonrefrigerated conditions of storage and distribution.

(5) "Commercial sterility of equipment and containers used for aseptic processing and packaging of food" means the condition achieved by application of heat, chemical sterilants, or other appropriate treatment that renders the equipment and containers free of viable microorganisms having public health significance, as well as microorganisms of nonhealth significance, capable of reproducing in the food under normal nonrefrigerated conditions of storage and distribution.

(6) "Critical factor" means any property, characteristic, condition, aspect, or other parameter, variation of which may affect the scheduled process and the attainment of commercial sterility.

(7) "Flame sterilizer" means an apparatus in which hermetically sealed containers are agitated at atmospheric pressure, by either continuous, discontinuous, or reciprocating movement, with impinging gas flames to achieve sterilization temperatures. A holding period in a heated section may follow the initial heating period.
