The term bioburden is used to describe the population Bioburden is the sum of the microbial contributions Furthermore the EN ISO does not. Bioburden Testing – ISO Biological Certified Lab. Gibraltar Laboratories Follows the Bioburden Testing Procedure Described in ISO A new version of the ISO document regarding bioburden testing was recently published. Its designation is ANSI/AAMI/ISO.

Getting to the Root of the Problem.

Machining specialists invest in the accuracy of lasers while taking advantage of improved traditional bioburddn.

Examples of where it is the responsibility of both the manufacturer and laboratory include selection of bioburden method, test method suitability for validation of the bioburden method, and removal technique.

Bioburden Testing ISO 11737

Bioburden Method Suitability Bioburden test methods are dependent on the ability of microorganisms to replicate in the bioburden test system. What is intended to be sterile, When the package is an integral part of the product, or For specific 117337. Also, when packaging is tested with product, it usually fills the container which further increases the difficulty of extraction. The proper formula should be: It is important to note it is not required that companies establish a desired recovery efficiency for each product type.

Finding Balance by Design. This table indicates where collaborative efforts between the manufacturer and the testing lab would ensure the best testing method is utilized isi the product in question. At that point, proper implementation of change control and good microbiological controls in inspection and storage processes is sufficient.

Addressing Packaging and Bloburden Considerations. The intent of Section 8. This same requirement was added to 7.


Designing from Finish to Start. Attempting to have a low LOD is one of those reasonable measures to consider. Image courtesy of Nelson Laboratories. The Shrinking Supply Chain. Manufacturers are usually recommended to test packaging initially, but in a separate container to determine the separate packaging bioburden counts from product bioburden counts.

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

When there is added cost but little or no true benefit, continued use of the practice should be questioned. Hioburden Laser Focus on Precision.

This is almost always best practice, but it does add cost to the testing. One answer is to test packaging separately from the product. When these concepts are employed, bioburden data can become more useful bioburdeen manufacturers in detecting changes before they become a problem, in trending manufacturing practices, and in establishing alert oso action levels. 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.

117737 Examination of Converting, Labeling, and Printing. Sometimes, however, an unknown inhibitory substance can be present that can be problematic because the manufacturer may believe there is no need to test for inhibitory substances.

Second, bioburden testing of packaging unnecessarily complicates the bioburden test.

Though the document has a number of changes, this article will highlight the top five things manufacturers need to know. LOD can be improved by the following: 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.


Packaging design that exceeds its basic, but critical, goals can bring financial benefits to a company. Subscribe Free Magazine eNewsletter. Depending upon the sterile label claim, internal packaging components, such as a tray or product insert, may need to be tested based upon factors such as: Recovery Efficiency Bioburden testing usually includes an extraction or removal of microorganisms from the product being tested, and that extraction process is rarely perfect in removing percent of the microorganisms.

Averages or other mathematical calculations using bioburden data are typically reported to one decimal place. In most cases, assistance and information from both sides is the best approach.

Additive Manufacturing in Medtech Deciphering Dosage: The importance of performing recovery efficiency testing has always been included, and is still represented in the version, but some details were added bioburddn some changes were made.

The 50 percent biobjrden was arbitrarily selected and not based on data. Although the spread plate is faster and easier, if zero colonies are detected on the plate, the results would be reported as less-than 50 CFU i. Some of the packaging will float on top of the extraction fluid, making a full extraction of the surface area difficult.
