ACU Program Announces Second Annual GOLD Day

Controlled Substances Drugs Guidelines Policies

Second Annual GOLD Day on May 3, 2024 icon

The Animal Care & Use (ACU) Program is pleased to announce that its second annual GOLD Day will take place on Friday, May 3, 2024.

Launched in 2023, GOLD Day is a unique opportunity for laboratories to set aside dedicated time for personnel to:

Go, Organize, Label, and Dispose of drugs, medical materials, surgical supplies, agents, and other substances administered to – or used in – ANY animal procedure.

The following list of tools and resources has been carefully curated to help laboratories structure their GOLD Day activities and assist with navigating the many nuanced requirements for the proper use of drugs and other medical materials in animal studies.

GOLD Day Resources

  • All drugs and other medical materials (including biologics, fluids, vehicles, supplies, etc.) must be stored in accordance with:
    • Manufacturer recommendations
    • U-M requirements
    • State of Michigan/DEA regulations (where applicable)
  • Items must be clearly labeled as expired AND segregated from non-expired items until they can be appropriately discarded (see Dispose tab below)
  • Review the Controlled Substances in Research Monitoring Program website for information about securing and storing controlled substances
  • Create and maintain a regular (e.g., monthly) schedule for reviewing substance expiration dates in your laboratory
  • Assign an individual, or individuals, in your laboratory to routinely monitor and organize substances, including a regular check of expiration dates. This individual should also serve as the point person for questions or concerns others in your laboratory may have about applicable policies and procedures

  • Check that all drugs, pharmaceuticals, and medical materials are current with labels that clearly indicate expiration dates
  • Verify that all sutures and dated medical supplies are within their expiration date OR segregated AND clearly labeled for in-vitro or terminal use only
  • Some pharmaceutics (e.g., items removed from their original container for dilution or combination with other agents) may have a “Use By Date” that differs from the product’s original expiration date. When a product’s shelf life is modified (i.e., shortened) based on when the product is opened for use/dilution, use whichever date (either “Use By Date” or “Original Expiration Date”) OCCURS FIRST to determine the product’s expiration
  • For supplies that do not have expiration dates, consider writing ‘No Exp’ on the bottle or package to easily identify these materials
