On April 29, 2024, the FDA held the sixth medical device sterilization town hall and discussed:

  • Suggestions the FDA received on potential topics for the sterilization town hall series.
  • How the FDA will pivot the format of the series to support more engaging discussions on topics of interest.


Sterilization is a critical step in the manufacturing process for certain medical devices. Sterilization of medical devices helps prevent serious infections. Inadequate sterilization can lead to life-threatening infections.

Medical devices are sterilized in a variety of ways including using moist heat (steam), dry heat, radiation, ethylene oxide (EtO) gas, vaporized hydrogen peroxide, and other sterilization methods (for example, chlorine dioxide gas, vaporized peracetic acid, and nitrogen dioxide).

Ethylene oxide is the most commonly used method to sterilize medical devices in the United States, and it is widely used by medical device manufacturers and contract sterilizers worldwide. Other existing sterilization modalities cannot currently replace the use of EtO for many devices. While some novel technologies hold promise, innovative alternative sterilization methods are still in early phases of research and development.

The FDA is committed to reducing reliance on EtO sterilization use while ensuring the integrity of the supply chain so that patients and providers have continued access to the sterile devices they need. To meet this goal, FDA continues to take a multipronged approach, including regulatory flexibilities, supply chain analysis and mitigation, collaboration, innovation, and communication, including this regular series of town halls.
