Definition of a single method for use in the determination of bioburden in all situations ixo not practicable because of the wide variety of designs and materials of construction of medical devices.

Manufacturers ios to understand the potential contribution to product bioburden that packaging can make. You may find similar items within these categories by selecting from the choices below:. Click to learn more. Averages or other ieo calculations using lso data are typically reported to one decimal place. The second variable is that the 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.

The guidance provides explanations and methods that are regarded as being a suitable means for complying with the requirements. An Examination of Converting, Labeling, and Printing. Sterilization of medical devices. Nor is it possible to define a single technique to be used in all situations for the removal of microorganisms in preparation for enumeration.

A Laser Focus on Precision. You may find similar items within these categories by selecting from the choices below:.

A knowledge of bioburden can be used in a number of situations as part of:. Once the data are gathered and it is determined that the results are acceptable, there is no need to test packaging on a routine basis. Find Similar Items This product falls into the following categories.

What medical device manufacturers need to know about the recent changes to the ISO bioburden standard. Examples of where it is the responsibility of both the manufacturer and laboratory include selection oso bioburden method, test method suitability for validation of the bioburden method, and kso technique.

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

Whereas, specification of acceptable bioburden ido and trending are the responsibility of the manufacturer and items such as preparation and sterilization of materials and microbial characterization are laboratory responsibilities. The Shrinking Supply Chain.


When there is added cost but little or no true benefit, continued use of the practice should be questioned. Thus, it is not possible to expect bioburden test results to be as accurate or precise as one would with an analytical chemistry test.

In an attempt to provide clearer guidance for both manufacturers and testing laboratories, a table of responsibilities has been included in Annex D. Even so, medical devices produced under standard manufacturing conditions in accordance with the requirements for quality management systems see, for example, ISO may, prior to sterilization, have microorganisms on them, albeit in low numbers. However, it is important to be aware that exposure to a properly validated and accurately controlled sterilization process is not the only factor associated with the provision of assurance that the product is sterile and, in this respect, suitable for its intended use.

Testing of Packaging The previous version of the standard was missing guidance regarding whether product packaging should be tested for bioburden or not.

Five Aspects Of The ISO Updates You Need To Know – Medical Product Outsourcing

First is that 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. Although it is not intended that these suggested values are exact cutoff points for either method, they do provide general guidance on when one might be more appropriate than the other.

The additions are specifically written so that a manufacturer might choose to omit performing the bioburden method suitability test if they have a detailed understanding of all components and manufacturing processes relating to their product.

Table of Responsibilities Although compliance with device standards is ultimately the responsibility of the manufacturer, there has been confusion in the industry regarding where some responsibilities lay. This table indicates where collaborative efforts between the manufacturer and the testing lab would ensure the best testing method is utilized for the product in question. Typically, it is sufficient to perform a bioburden determination on a product after its removal from its packaging system and to omit the packaging system from the determination.

The medical devices sterilization industry Why should you use this standard? Bioburden Method Suitability Bioburden test methods are dependent on the ability of microorganisms to replicate in the bioburden test system. Find Similar Items This product falls into the following categories. For this reason, sterilization processes are validated for use, the performance of the sterilization process is monitored routinely and the equipment is maintained.

Take the smart route to manage medical device compliance. It specifies requirements and provides guidance on the enumeration and microbial characterization of the population of viable microorganisms on or in a health care product, component, raw material or package.

NOTE 1 The nature and extent of microbial characterization is dependent on the intended use of the bioburden data. The effectiveness of the bioburden extraction process is determined in a recovery efficiency test. Both tests are in place to ensure there is nothing in the test system that will inhibit viable microorganisms from replicating. Methods other than those given in the guidance may be used, if they are effective in achieving compliance with the requirements of this part of BS EN ISO Determination of a population of microorganisms on products BS EN ISO Part 1 specifies the requirements to be met in the determination of bioburden.

Furthermore, the selection of conditions for enumeration of microorganisms will be influenced by the types of microorganism likely to be present on or in medical devices. Such products are non sterile. By using our website, you declare yourself in agreement with our use of cookies. The purpose of sterilization is to inactivate the microbiological contaminants and thereby transform the non-sterile products into sterile ones.

Search all products by. The main changes compared to the previous edition are isp follows: However, if bioburden recovery efficiency results fall below a target or desired value, another technique should be attempted e. This is almost always best practice, but it does add cost to the testing. To control bioburden, attention must be given to the microbiological status of these sources.
