Summary

The FDA is delaying the effective date of its final order regarding the expanded use of spirulina extract as a color additive in human foods. This delay is in response to timely objections and a request for a hearing filed by Obelisk Tech Systems Inc. The agency will announce a new effective date or other administrative action later.

What changed

The Food and Drug Administration (FDA) has issued a final order to delay the effective date of its February 6, 2026, final rule concerning the expanded use of spirulina extract as a color additive in human foods. This delay is mandated by law following the submission of timely objections and a hearing request by Obelisk Tech Systems Inc. The original rule aimed to broaden the safe use of spirulina extract, lower heavy metal specifications, and add a cadmium specification. The FDA emphasizes that this delay does not alter its initial determination of reasonable certainty of no harm from the additive.

Compliance officers should note that the original effective date of March 20, 2026, is now indefinitely delayed. The FDA will publish a separate document to announce a new effective date or other administrative actions. Regulated entities involved in the use of spirulina extract as a color additive should monitor future FDA announcements regarding the final resolution of the objections and the establishment of a new effective date for the rule.

What to do next

  1. Monitor future FDA Federal Register publications for updates on the effective date of the spirulina extract color additive rule.
  2. Review the original final order and the objections filed by Obelisk Tech Systems Inc. to understand the basis for the delay.

ACTION:

Final order; delay of effective date.

SUMMARY:

The Food and Drug Administration (FDA or we) is announcing a delay of the effective date of our February 6, 2026, final order
to amend the color additive regulations to provide for the expanded safe use of spirulina (Arthrospira platensis) extract as a color additive in human foods generally (except for infant formula, certain foods subject to regulation by
the U.S. Department of Agriculture (USDA), and foods for which standards of identity have been issued under section 401 of
the Federal Food, Drug, and Cosmetic Act (FD&C Act), unless the use of the added color is authorized by such standards) at
levels consistent with good manufacturing practice (GMP); to lower the heavy metal specifications for lead, arsenic, and mercury;
and to add a specification for cadmium. The delay of the effective date is required by law following the filing of timely
objections and a request for a hearing on the final order. This announcement does not reflect a change in our determination
that there is a reasonable certainty of no harm from the use of this color additive under the conditions of its intended use.
In addition, this announcement does not constitute a determination that all of the issues raised in the submission constitute
objections or that a hearing is justified on any objections or requests for a hearing that have been filed.

DATES:

As of March 20, 2026, the effective date of the final order published February 6, 2026 (91 FR 5291) is delayed indefinitely.
The Food and Drug Administration will publish a document in the
Federal Register
announcing a new effective date or other administrative action on the order.

SUPPLEMENTARY INFORMATION:

In the
Federal Register
of February 6, 2026 (91 FR 5291), FDA issued a final order, Listing of Color Additives Exempt from Certification; Spirulina Extract, to provide for the expanded safe use of spirulina (Arthrospira platensis) extract as a color additive in human foods generally (except for infant formula, certain foods subject to regulation by
the USDA, and foods for which standards of identity have been issued under section 401 of the FD&C Act, unless the use of
the added color is authorized by such standards) at levels consistent with good manufacturing practice (GMP); to lower the
heavy metal specifications for lead, arsenic, and mercury; and to add a specification for cadmium. Specifically, the final
order amended § 73.530, titled “Spirulina extract,” (21 CFR 73.530). We issued the final order in response to a color additive
petition submitted by GNT USA, LLC. We gave interested persons until March 9, 2026, to file objections and requests for a
hearing on the final order.

Obelisk Tech Systems Inc. submitted objections and a request for a hearing. See Submission from Obelisk Tech Systems Inc.,
to the Dockets Management Staff, Food and Drug Administration, submitted March 7, 2026. In addition to the objections and
request for a hearing submitted by Obelisk Tech Systems Inc, we received another comment that opposed the final order, but
does not appear to be an objection under 21 CFR 12.22 nor does it request a hearing. We plan to address the objections and
request for a hearing in a future document.

Under sections 701(e)(2) and 721(d) of the FD&C Act (21 U.S.C. 371(e)(2) and 379e(d)), within 30 days after publication of
an order relating to a color additive regulation, any person adversely affected by such an order may file objections, specifying
with

  particularity the provisions of the order deemed objectionable, stating the grounds therefor, and requesting a public hearing
  upon such objections. The filing of the objections operates to delay the effective date of the final order until we take final
  action on the objections. [(1)]() Our announcement of the delay of the effective date of the final order does not reflect a change in our determination that
  there is a reasonable certainty of no harm from the use of this color additive under the proposed conditions of its intended
  use. In addition, this notification does not constitute a determination that all of the issues raised in the submission constitute
  objections or that a hearing is justified on any objections or requests for hearing that have been filed.

For access to the docket to read the objections received, go to https://www.regulations.gov and insert the docket number FDA-2024-C-3384 into the “Search” box and follow the prompts and/or go to the Dockets Management
Staff, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.
