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. An aseptic sampling arrangement for a fluid enclosure, comprising: a) a septum configured for receipt within an aperture of a fluid enclosure, the septum including a boot, the boot being constructed to seal the aperture of the fluid enclosure and provide for penetration of a needle therethrough; and b) a tamper-resistant locking arrangement that permits access to the septum only when the tamper-resistant locking arrangement is unlocked. 2. The sampling arrangement of claim 1, further including a securing element configured to secure the septum within the aperture of the fluid enclosure. 3. The sampling arrangement of claim 2, wherein access to the septum and the securing element is permitted only when the locking arrangement is unlocked. 4. The sampling arrangement of claim 3, wherein the securing element is a threaded nut. 5. The sampling arrangement of claim 1, wherein the locking arrangement includes: a) abase; b) a cover sized to fit over the septum; and c) a locking device arranged to secure the cover in relation to the base. 6. The sampling arrangement of claim 5, further including a securing element configured to secure the septum within the aperture of the fluid enclosure, wherein the base of the locking arrangement prevents access to the securing element. 7. The sampling arrangement of claim 6, wherein the septum and the securing element are enclosed within the base and the cover to prevent unwanted access to the internal volume of the fluid enclosure. 8. The sampling arrangement of claim 7, wherein the base includes sides extending outward from a main portion, and wherein the cover is sized to fit between the sides of the base to enclose the septum and the securing element. 9. The sampling arrangement of claim 1, wherein the septum further includes a cap piece and a penetrable layer at least partially covering a portion of the cap piece. 10. The sampling arrangement of claim 1, wherein the septum is configured for receipt within an aperture of a transportable fluid vessel. 11. The sampling arrangement of claim 1, wherein the septum is configured for receipt within a tanker truck. 12. An aseptic sampling arrangement for a fluid enclosure, comprising: a) a septum constructed to seal an aperture of the fluid enclosure and provide for penetration of a needle therethrough; b) a securing element sized to secure the septum within the aperture of the fluid enclosure; c) a locking arrangement that prevents unwanted access to the septum and the securing element, the locking arrangement including a cover positioned over the septum; and d) a locking device that locks the locking arrangement in relation to the septum and the securing element; e) wherein access to the fluid enclosure through the aperture is permitted only by unlocking the locking device and removing the cover. 13. The sampling arrangement of claim 5, wherein the securing element is a threaded nut. 14. The sampling arrangement of claim 13, wherein the locking arrangement further includes a base, the securing element being enclosed by the base and the cover such that the securing element is accessible only by unlocking the locking device and removing the cover. 15. The sampling arrangement of claim 14, wherein the base includes sides extending outward from a main portion, and wherein the cover is sized to fit between the sides of the base to enclose the septum and the securing element. 16. The sampling arrangement of claim 15, wherein the locking device is inserted through apertures defined by the sides of the base to secure the cover in relation to the base.
