A method of using an aseptic sampling arrangement. The sampling arrangement includes a septum cartridge and a securing element for use with a fluid enclosure. A locking arrangement is provided to allow selective access to the septum cartridge and the securing element. The sampling arrangement further includes a needle, a tube, and a collection bag. The sampling arrangement can be used to monitor the quality of a fluid product. The method of monitoring includes obtaining a fluid product sample from the fluid enclosure within the collection bag. The collection bag is then incubated for a period of time during which oxygen permeates the bag to simulate post-pasteurizing conditions and/or pre-pasteurizing conditions of the fluid product. The method further includes monitoring the level of contamination detected within the fluid product sample.

I claim: 1. A method of monitoring quality of a post-pasteurized milk product, the method comprising the steps of: a) providing an aseptic sampling arrangement including a septum and an oxygen permeable collection bag; b) obtaining a sample of the post-pasteurized milk product by aseptically collecting the post-pasteurized milk product in the collection bag; c) incubating the collection bag for a period of time including exposing the collection bag to oxygen such that the oxygen permeability of the collection bag permits oxygen saturation of the sample of post-pasteurized milk product; and d) monitoring the level of contamination within the sample of post-pasteurized milk product during the period of time, including: i) determining a level of gram-negative bacteria present within the sample of the post-pasteurized milk product wherein gram-negative bacteria is detected within approximately six days. 2. The method of claim 1, wherein the step of exposing the oxygen permeable collection bag includes simulating storage conditions of the milk product. 3. The method of claim 2, wherein the step of simulating storage conditions includes simulating an oxygen saturated milk product without adding oxygen to the sample of milk product. 4. The method of claim 1, wherein the septum is positioned within an aperture of an enclosure containing the milk product, and wherein the step of obtaining a sample of milk product further includes inserting a penetrating member into the septum to provide fluid communication between the enclosure and the collection bag, the penetrating member .and the collection bag being interconnected by a tube.
