Biological indicators are directly used to validate the sterilization process in different industries, and at this point, it has proven to be the most important indicator to determine the sterilization process.

It is well known that the direct use of biological indicators can verify the sterilization process in different industries, at this point, it should be noted that they are indicators that determine the lethality of the sterilization process, in short this means that they are responsible for showing that the material has undergone a Whether there are live microorganisms during the sterilization process.

In other words, biological indicators that are usually extremely important are obviously prepared from bacterial spores that are highly resistant to the sterilization methods used, these spores and then those that serve as test organisms, and they are exposed to the sterilization process at the same time as the material's The problem, is a sanitization.

Therefore, post-sterilization treatment biological indicators will be fully analyzed to determine whether viable spores are still present or not, in the case of surviving spores in the product, the sterilization process is automatically discarded, and in the opposite case, if no surviving spores For spores, the sterilization process is normal for verification.

If the spores survive after sterilization and the biological indicators hatch, for a short time at the end of the incubation period, the same biological indicators are observed, at this time if the liquid changes color or fails to observe the turbidity, it confirms the growth of the spores, so the sterilization process should be To be ruled out, on the contrary, if you do not notice any type of change in the appearance of the liquid immediately verify the sterilization process, it is also extremely important to note that there are a lot of lectures on biological indicators today that also contain acid-base indicators, which themselves change color if The spores grow, so this makes growth detection much easier as it is unambiguous.

Due to the high quality standards in the pharmaceutical and food industries and health, it is now necessary to have a wide or strict control of the sterilization process, the sole purpose of which is to be able to avoid the risk of contamination, thereby affecting in one way or another either the product or the user itself.

We have to tell you that in short biological indicators can be used to verify that a certain sterilization process has actually been carried out correctly, so that all materials can actually be sterilized after this 100% sterility is exposed to some sterilization process, today There are many methods of disinfection, which is why each method has a specific biological indicator that itself validates the process in question.
