Biological indicators are directly used to be able to validate sterilization processes in different industries, at this point, they turn out to be indicators that determine the lethality of a sterilization process.

As many of you already know, biological indicators are directly used to be able to validate sterilization processes in different industries, at this point, it should be noted that they turn out to be indicators that determine the lethality of a sterilization process, in short this means that they are responsible for indicating whether a material that undergoes a sterilization process is completely free of living microorganisms or not.

It is vitally important to explain that normally a biological indicator is clearly composed of a preparation of bacterial spores, the same that turn out to be highly resistant to the sterilization method to be used at that time, such spores are then those that are used as test organisms, which are exposed to the sterilization process at the same time as the material in question that is the one to be sterilized.

Therefore, after this sterilization process the biological indicator will be fully analyzed, in order to be able to determine whether there are still viable spores in it or not, in the case of surviving spores in the product, the sterilization process is automatically discarded, while in the opposite case, if there are no surviving spores, the sterilization process is validated as normal.

Then to analyze if spores survived after sterilization, biological indicators are incubated, for a short period of time, so at the end of this incubation period, the same biological indicators are observed, at this point if the liquid changes color or failing to observe turbidity in it, it confirms growth of spores , so the sterilization process should therefore be ruled out, instead if you do not notice any type of change in the appearance of the liquid is immediately validated from the sterilization process, here is also extremely important to note that today there are many presentations of biological indicators also contain a pH indicator, this in itself changes color if the spores grow , therefore this makes growth detection really much easier as it is clear.

Thanks to the high quality standards in both the pharmaceutical and food industry and health, there must currently be a wide or strict control for sterilization processes, with the sole aim of being able to avoid contamination risks, which can then affect in one way or another or the product or the user itself.

To conclude with this interesting topic, we have to tell you that in a nutshell a biological indicators are used to be able to validate that a certain sterilization process has actually been carried out correctly and therefore can give all the certainty that the material to be actually sterilized this 100% sterile after having exposed it to some sterilization process , we must also be very aware that today there are many methods to sterilize, that is why for each method there is a specific biological indicator that allows in itself to validate the process in question.
