The U.S. Food and Drug Administration (FDA) has become aware of the potential for healthcare facility staff that reprocess and sterilize medical devices to misinterpret the indicators used to validate the sterilization of medical devices because there is no standard indicator color to indicate a sterilized device.

Healthcare facilities alerted the FDA that, among manufacturers of hydrogen peroxide vapor sterilization systems:
The 3M Comply Hydrogen Peroxide Chemical Indicator 1248 uses blue to indicate an unprocessed device and pink to indicate a sterilized device.
The Aesculap MD334 Process Indicator Card uses pink/magenta to indicate an unprocessed device and blue to indicate a sterilized device.
There have been no injuries reported to the FDA associated with the use of these indicators.
The FDA recommends healthcare facilities and reprocessing staff:
· Review the manufacturer’s instructions for the particular indicator bar or card being used and know the significance of the indicator colors.
· Enhance staff training on the indicators for all sterilization systems employed in the facility and reinforce that training with prominently displayed visual reminders.
The 3M Comply Hydrogen Peroxide Chemical Indicator 1248 Card uses blue to indicate unprocessed and pink to indicate processed.
The Aesculap MD334 Process Indicator Card uses pink/magenta to indicate unprocessed and blue to indicate processed.
During the COVID-19 pandemic, healthcare facilities are rapidly adopting conservation practices, including decontaminating disposable compatible N95 and N95-equivalent respirators for single-user reuse. Reprocessing staff may be using sterilization systems for the first time or concurrently using sterilization systems from different manufacturers. If staff assume that all manufacturers use the same color code to validate sterilization, they may mistakenly release contaminated devices for reuse.
There is no standard color to indicate validated sterilization. Each manufacturer has developed its own color scheme to validate the sterilization process, and the colors vary among manufacturers even though many are validated for the same cycle conditions.
The FDA is collaborating with manufacturers of sterilization systems to improve product labeling and explore standardization for colors used to indicate sterilization. The FDA will continue to keep healthcare providers, manufacturers, and the public informed of new or additional information.
The FDA encourages healthcare providers to report any adverse events or suspected adverse events experienced with any sterilization indicators.
· FDA Device manufacturers and user organizations must comply with the applicable Medical Device Reporting (MDR) regulations.
· Healthcare personnel employed by organizations that are subject to the FDA's user facility reporting requirements should follow the reporting procedures established by their organizations.
· Prompt reporting of adverse events can help the FDA identify and better understand the risks associated with medical devices.
