If a biological indicator shows growth after a sterilization cycle, what does this indicate?

Biological indicators are the definitive test of whether a sterilization cycle actually kills microorganisms. If the indicator shows growth after the cycle, the spores survived, meaning the cycle did not achieve the required spore kill. Sterility cannot be guaranteed for the load, and the process must be revalidated and the items reprocessed under proper parameters. Chemical indicators only confirm exposure to the sterilant, not that all organisms were killed, and while improper packing can contribute to issues, growth in a biological indicator specifically signals a failure of the sterilization process itself.
