Sterilization is one of the most critical processes in the healthcare and medical device industry. It ensures that medical devices, pharmaceutical products, and healthcare materials are free from viable microorganisms before reaching patients and healthcare professionals. Among the many sterilization technologies available today, Ethylene Oxide Sterilization and Gamma Sterilization remain two of the most widely used methods globally. Although both methods achieve sterility as

After being involved in the medical device industry for more than 10 years, I found that despite newer technologies and sterilization methods that have come up to so call replace Ethylene Oxide as a sterilization agent, it still remains as the number one choice for sterilization of medical devices. This is of course mostly due to its unique compatibility with heat or moisture sensitive materials or with medical devices with complex geometries. The chemical structure of ethyle

Introduction Biological indicators (BIs) are widely recognized as the gold standard for monitoring the effectiveness of sterilization processes. Following exposure, BIs are incubated to allow any surviving microorganisms to recover and grow. Traditionally, international standards have defined seven days as the reference incubation period for established sterilization processes such as moist heat (steam) and ethylene oxide (EO). However, advances in spore production, culture

B/F test is a fundamental component of sterility method validation performed to ensure that a product does not interfere with the detection of viable microorganisms during sterility testing.

Introduction Sterility testing is critical in the pharmaceutical and medical device industries because it ensures that products intended for patient use are free from viable microorganisms. To perform sterility testing, two commonly referenced standards are available: USP <71> Sterility Tests and ISO 11737‑2: Sterilization of Health Care Products – Microbiological Methods, Part 2: Test of Sterility performed in the definition, validation, and maintenance of a sterilization p

Bioburden, the population of viable microorganisms found on a medical device, pharmaceutical raw material, or product prior to sterilization; is a critical parameter in medical device manufacturing. Determining the precise bioburden is essential for validating sterilization processes, ensuring product safety, and complying with stringent regulatory standards. The "best" testing method is not a one-size-fits-all solution; rather, it is a strategic choice based on the sample’s

Background Sterility testing is one of the most critical steps in ensuring the safety and compliance of medical devices, pharmaceuticals, and other healthcare products. However, before sterility testing can be performed, regulatory guidelines such as USP <71> Sterility Tests and ISO 11737-2 require a preliminary check called the Sterility Method Suitability Test, commonly referred to as the Bacteriostasis and Fungistasis (B&F) Test. Why is this step so important? Because cert

Today, we’re going deeper into the microbial identification process, specifically, how to determine the source of microbial contamination in your facility. While this method doesn’t guarantee pinpoint accuracy, it offers valuable insights that can guide your environmental monitoring and root cause analysis.

Microorganism identification is the process of determining the species of microbes found during bioburden or environmental testing.

This study found that after 6 days in the icebox with temperatures of roughly 20˚C, the EO recovery is still within an acceptable range. However, this does not extend to ECH and EG residues, which have a recovery rate of less than 80% after Day 1, possibly due to the increase in temperature above 10˚C.
