For a healthcare product to be considered sterile the traditional options that have been accessible to a manufacturer are either terminal sterilization to a maximal sterility assurance level SAL of 10 6 or aseptic processing.

Sterility assurance level SAL refers to the probability of a microorganism surviving the sterilization process making the item non-sterile. For aseptic processes a SAL is not applicable as accidental 56 contamination caused by inadequate technique cannot be reliably eliminated by monitor ing control or. The concept of what constitutes sterile is measured as a probability of sterility for each item to be sterilized.

In practice the sterile state cannot be proven. Which in terms of 10-n the SAL indicates the expected probability of finding a viable microorganism on a medical device.

Sterility Assurance Levels SAL A sterile medical device is free from all viable microorganisms. This probability is referred to as a sterility assurance level SAL. Instead sterility is expressed as the probability of a single viable microorganism occurring on an item after sterilization.

Selection of an appropriate Sterility Assurance Level SAL for medical devices. Appropriate known-to-be-sterile finished articles should be employed periodically as negative controls as a. Sterile hospital instruments must undergo sterilization and SAL.

A SAL of 106 SAL6 is considered the standard for medical devices and defines the probability of 1 in 1 000 000 that a device is not sterile 108. For each additional two.

Sterility Assurance Level SALs are used to quantify the level or probability of sterility achieved through a certain sterilization process. This probability is commonly referred to as the sterility assurance level SAL of the product and is defined as the probability of a single viable. Read more about the sterility assurance level HERE.

Generally in sterilization it is required to achieve a SAL sterility assurance level of 10 6 and an additional 6 log reduction. Sterility Assurance Level and Aseptic Manufacturing Process in Pharmaceuticals Yasir Mehmood Faculty of Pharmacy University of Central Punjab Lahore Pakistan E-Mail. Whether sterilization takes place using thermal effects heat photo effects UV energy or nuclear effects irradiation each level of increasing efficacy costs energy and well as time.

Free from viable microorganisms. Indicators of health services. The sterility of a product is defined by the probability of a single viable microorganism occurring on an item after sterilization.

Many factors go into this selection but since the choice of SAL is directly related to sterilization dose this decision is critical to making a sterile claim on any product and one must consider the impact on the product design materials selection customer. This means there is a one in ten thousand 10-4 chance of a single viable Bst spore surviv-ing the process. Steam Sterilization Principles of at least 20 minutes at 121C 250F for a Sterility Assurance Level SAL of 10-4 assuming a starting population of one million 106 organisms.

This TechTip provides information on the selection of an appropriate Sterility Assurance Level SAL for medical devicesMany factors go into this selection but since the choice of SAL is directly related to sterilization dose this decision is critical to making a sterile claim on any product and one must. The current standard for pharmacopoeial sterilization procedures requires a probability of one viable microorganism or less in one million sterilized items of the final product and that means a SAL of 10. Other specifications may include sterilant residues and endotoxin levels.

This figure expresses the probability of a single itemin a batch being non-sterile after being subjected to a sterilization process. Sterilization techniques based on bioburden destruction by heat or irradiation require a. Approach to Sterility.
