Should a Volcanic Mineral Be Approved for Livestock Feed Pellets?

Official title: Share your thoughts: Proposed new livestock feed ingredient – Dactic tuff breccia

Closed Regulations & Permits Agriculture & Food
The CFIA asked whether dacitic tuff breccia—a volcanic mineral—should be approved as a pelleting aid in livestock feed. The agency's evaluation found it safe for animals, workers, and the environment. If approved, feed manufacturers could use up to 2% of this ingredient to help bind feed pellets together.

Why This Matters

This one's pretty niche. Unless you work in livestock feed manufacturing or supply feed ingredients, it probably won't affect your daily life. The ingredient helps pellets stick together—not exactly dinner table conversation.

What Could Change

If no major concerns were raised, dacitic tuff breccia will be added to the Canadian Feed Ingredients Table. Feed manufacturers will be able to use it as a pelleting aid at up to 2% of the feed. Labels will need to include worker safety warnings about potential eye, skin, and respiratory irritation.

Key Issues

  • Is the proposed description for dacitic tuff breccia accurate?
  • Is there additional scientific data that should be considered before approval?
