Five Aspects of the ISO 11737-1:2018 Updates You Need to Know

The purpose of sterilization is to inactivate the microbiological contaminants and thereby transform the non-sterile products into sterile ones. Furthermore, the requirements specified in this ios of BS EN ISO are not intended to address the removal and detection of the causative agents of spongiform encephalopathies such as scrapie, bovine spongiform encephalopathy and Creutzfeldt-Jakob disease. Since guidance on this topic was excluded from the standard, some manufacturers performed routine bioburden testing for all inner packaging.

International standards that specify requirements for validation and routine control of sterilization processes, require, when it is necessary to supply a sterile medical device, that adventitious isoo contamination of a medical device prior to sterilization be minimized.

Attempting to have a low LOD is one of those reasonable measures to consider. The guidance provides explanations and methods that are regarded as being a suitable means for complying with the requirements. However, if bioburden recovery efficiency results fall below a target iao desired value, another technique should be attempted e. LOD can be improved by the following: We use cookies to make our website easier to use and to better understand your needs.

Successfully navigating the maze of foreign medtech regulations requires diligence and proactive planning. It is important isl note it is not required that companies establish a desired recovery sio for each product type.

Microbiological methods Tests of sterility performed in the definition, validation and maintenance of a sterilization process.

Worldwide Standards We can source any standard from anywhere in the world. For a given treatment, the probability of survival is ios by the number and resistance of microorganisms and by the environment in which the organisms exist during treatment. Manufacturers are usually recommended to test packaging initially, but in a separate container to determine the separate packaging bioburden counts from product bioburden counts.

Based on this detailed understanding a manufacturer might know for a fact there are no inhibitory substances on, or in, their product and can provide a written rationale for not performing the test.

Though the document has a number of changes, this article will highlight the top five things manufacturers need to know. Sterilization of health care products. Having this information, with the example and ideas on improving LODs, is a benefit to the industry.


The formula placed into the standard is incorrect and is in the process of being corrected. Thus, it is not possible to expect bioburden test results to be as accurate or precise as one would with an analytical chemistry test. kso
