The apparatus for indicating biological content within a container of claim 8 , wherein the electronic sterility indicator monitors the biological content within the interior compartment and records a quantity data corresponding to at least one of the monitored biological content, the sterilization process and a characteristic associated with the sterilization process.

10. The apparatus for indicating biological content within a container of claim 9 , wherein the characteristic associated with the sterilization process includes at least one of a sterilization process temperature and a sterilization process duration.

11. The apparatus for indicating biological content within a container of claim 1 , further comprising an angled mounting portion within the cover, wherein the pressure-activated biological indicator is mounted proximate to the angled mounting portion, and wherein the angled mounting portion is sized to drain a quantity of condensate away from the pressure-activated biological indicator.

12. The apparatus for indicating biological content within a container of claim 1 , wherein the pressure-activated biological indicator further comprises a flexible membrane, wherein the flexible membrane is deformed when a pressure level of the pressurizable, enclosable, sterilizable interior compartment is greater than the atmosphere exterior of the medical sterilization container.

13. A method for indicating biological content within a container, the method comprising the steps of:

subjecting a medical sterilization container having a cover removably attached to the medical sterilization container to a sterilization process, wherein the medical sterilization container has a pressurizable, enclosable, sterilizable interior compartment formed by the medical sterilization container and the cover, wherein the interior compartment is sized to house at least one medical instrument; and

indicating a biological content within the pressurized, enclosable, sterilizable interior compartment with a pressure-activated biological indicator affixed within at least one of the cover and a wall of the medical sterilization container and in communication between both the interior compartment and an atmosphere exterior of the medical sterilization container after a completion of the sterilization process and after the atmosphere exterior of the medical sterilization container is substantially at an atmospheric level.

14. The method for indicating biological content within a container of claim 13 , further comprising the step of affixing the biological indicator in a location within the cover that allows it to be viewable from a position external to the interior compartment when the cover is attached to the medical container.

15. The method for indicating biological content within a container of claim 13 , further comprising the step of positioning an additional biological indicator fully within the interior compartment.

16. The method for indicating biological content within a container of claim 13 , further comprising the step of indicating with an additional biological indicator the presence of a biological content by a change in temperature, wherein the additional biological indicator is viewable from a position external to the interior compartment when the cover is attached to the medical sterilization container.

17. The method for indicating biological content within a container of claim 13 , wherein the step of indicating a biological content within the pressurized, enclosable, sterilizable interior compartment with the pressure-activated biological indicator further comprises the step of contacting a colored membrane having a first color with the pressure-activated biological indicator, thereby producing a second color when the pressure-activated biological indicator contacts the colored membrane.

18. The method for indicating biological content within a container of claim 13 , further comprising the step of indicating with an additional biological indicator the presence of a biological content with a an electronic sterility indicator at least partially located within the interior compartment.

19. The method for indicating biological content within a container of claim 18 , wherein the step of indicating with the additional biological indicator the presence of a biological content with a an electronic sterility indicator further comprises the steps of:

monitoring the biological content within the interior compartment;

recording a quantity data corresponding to at least one of the monitored biological content, the sterilization process, and a characteristic associated with the sterilization process; and

communicating at least a portion of the quantity of data corresponding to the at least one monitored biological content to a receiver.

20. The method for indicating biological content within a container of claim 13 , wherein pressure-activated biological indicator further comprises a flexible membrane, wherein the step of indicating a biological content within the pressurized, enclosable, sterilizable interior compartment with the pressure-activated biological indicator further comprises the steps of:
