If you come across a sterile tray that has no expiration date on it, what should you do?

• A. Consider it unsterile
• B. Use it anyway
• C. Autoclave again
• D. Discard

Answer: (A)

Sterility verification relies on an expiration date to guarantee that the packaging has remained intact and the contents are still sterile. If a sterile tray has no expiration date, you cannot confirm its sterility, and using it risks contamination and infection. The safest course is to treat it as unsterile and not use it. In practice, you would remove it from use and replace it with a verified sterile tray or follow your facility’s procedure for reprocessing only if you can confirm the packaging integrity and any required validation. Reautoclaving isn’t a guaranteed fix when the shelf life and packaging integrity are unknown, and using it anyway is unsafe.
