Determination of a population of microorganisms on products Status: The second variable is that isl test is meant to detect living organisms, and organisms vary in how they replicate, remain static, or die due to subtle differences in their environment. Generic requirements of the quality management system for design and development, production, installation and servicing are given in ISO and particular requirements for quality management systems for medical device production are given in ISO Testing of Packaging The previous version of the standard was missing guidance regarding whether product packaging should be tested for bioburden or not.

In most cases, assistance and information from both sides is the best approach. Research, Develop, Produce, Repeat. Getting to the Root of the Problem. Furthermore, the requirements specified in this part 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 iwo.

This is almost always best practice, but it does add cost to the testing. Determination of a population of microorganisms on products. When an inhibitory substance is present, the bioburden test results can look very low e. Therefore, the LOD for this example is 4.

Sterilization of medical devices. Some might say that contaminated packaging can transfer microorganisms to product, which then can transfer to the patient.


An example of this is the debate between a spread plate test method of 1. First is oso packaging usually does not have direct contact with the patient, which makes the potential risk to the patient lower for the packaging than for product itself. However issues associated with swabbing such as poor recovery efficiency from the surface to the swab and then poor recovery from the swab to the test system indicate this might not be the best method.

However, if bioburden recovery efficiency results fall below a target or desired value, another technique should be attempted e. Some of the packaging will float on top of the extraction fluid, making a full extraction of the surface area difficult.

Such products are non sterile. Definition of a single method for use in the determination of bioburden in all situations is not practicable because of the wide variety of designs and materials of construction of medical devices. The formula placed into the standard is incorrect and is in the process of being corrected.

In an effort to correct this practice, guidance was added to section A. Learn more about the cookies we use and how to change your settings. This same requirement was added to 7. Packaging design that exceeds its basic, but critical, goals can bring financial benefits to a company.

What is intended to be sterile, When the package is an integral part of the product, or For specific evaluation.

Some in the industry believed that routine testing of all interior packaging was required e. Search all products by. Microbiology, Biological analysis and testing, Quality management, Medical instruments, Sterilization hygieneCount methods microbiologySterile equipment, Packaging, Microbiological analysis, Medical equipment. Furthermore, for the effective validation and routine control of a sterilization process, it is important to be aware of the microbiological challenge that is presented in the process, in terms of number, characteristics and properties of microorganisms.


The importance of performing recovery efficiency testing has always been included, and is still represented in the version, but some details were added and some changes were made.

Addressing Packaging and Sterilization Considerations. NOTE 1 The nature and extent of microbial characterization is dependent on the intended use of the bioburden data.

For a given treatment, the probability of survival is determined by the number and resistance of microorganisms and by the environment in which the organisms exist during treatment. Part 1 of BS EN ISO does not specify requirements for the microbiological monitoring of the environment in which medical devices are manufactured. Additive 111737-1 in Medtech Deciphering Dosage: Application of risk management to medical devices.

Both traditional and isi prototyping technologies are seeing increased use to get products to market faster. Having this information, with the example and ideas on improving LODs, is a benefit to the industry.

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

The main changes compared 11773-1 the previous edition are as follows: Second, bioburden testing of packaging unnecessarily complicates the bioburden test. Please download Chrome or Firefox or view our browser io. Determination of a population of microorganisms on products Status: Find Similar Items This product falls into the following categories. Since guidance on this topic was excluded from the standard, some manufacturers performed routine bioburden testing for all inner packaging.

Attempting to have a low LOD is one of those reasonable measures to consider.
