A preform (31) is sterilized by a preform sterilizer (11). The preform (31) is blow-molded by a blow-molding device (13) to manufacture a container (30). Next, the container (30) is filled with a culture medium by a filling device (20) without sterilizing the container (30) by a container sterilizer (15), and the container (30) is plugged by a plugging device (21). Thereafter, it is verified how much microorganism survive or propagate in the culture medium in the container (30). A degree of sterilization in the container sterilizer (15) is adjusted on the basis of a verification result.

A system for simultaneously forming and filling a container from a thermoplastic polymer preform with a carbonated liquid at ambient temperature. The system includes a mold that encloses the thermoplastic polymer perform, a stretching member that stretches the thermoplastic polymer preform, an injection head that inject the carbonated liquid, and a pressurization system. The pressurization system is configured to, with the carbonated liquid beverage at room temperature (68 F. to 77 F.), increase pressure of the carbonated liquid beverage to a pre-load pressure that is greater than the defined partial pressure of dissolved carbon dioxide in the resultant filled and sealed container at room temperature, to maintain the carbonated liquid beverage at rest and at the pre-load pressure prior to injecting into the preform.
