FDA Rejects Bid for Hearing on Red No. 3 Ban
The Food and Drug Administration has rejected a request for a public hearing regarding the agency’s final order to revoke authorizations for FD&C Red No. 3 in food and ingested drugs. The agency’s decision closes the door on an objection filed by Micro-Tracers, a company that utilizes the dye in tracer compounds for medicated animal feeds.
Science and Law Behind the Decision
The revocation of the color additive listings was not driven by concerns about the safety of Red 3 in its authorized uses, but rather by a legal mandate. FDA officials determined that high doses of the dye cause cancer in rats through a mechanism that does not apply to humans. Consequently, the agency moved to repeal the regulations based on the Delaney Clause of the Federal Food, Drug, and Cosmetic Act, which prohibits the approval of any substance found to induce cancer in humans or animals.
The objection submitted by Micro-Tracers contested the scientific basis for this revocation. The company argued that FDA failed to consider the specific use of the dye in tracers and requested an exemption or a new safety tolerance for that application. The agency addressed these concerns directly, stating that the repeal was a legal decision rather than a determination of safety for a particular intended use. FDA also rejected the argument that the tracer use was not subject to the Delaney Clause because it was neither a color additive nor a food additive.
Officials clarified that Red 3 was added “for purposes of imparting color during a quality assurance testing phase,” which classifies it as a color additive. Even if it were not considered a color additive, the filing noted that it would still be classified as a food additive because it is intentionally added to the feed.
While the filing of the objection had temporarily paused the repeal through an automatic stay, FDA’s denial of the request has lifted this restriction. The agency confirmed the effective dates for the removal of authorizations. The ban on Red 3 in food products will take effect on January 15, 2027, while the restriction on ingested drugs is set for January 18, 2028.
Given the strict nature of the Delaney Clause, the agency’s refusal to grant a hearing suggests a rigid adherence to statutory requirements. It remains to be seen if companies relying on tracer technology will develop alternative methods for quality assurance that do not require FDA-approved color additives, or if they will seek to challenge the classification of their specific applications through other legal avenues.
Regulatory bodies often update job contract rules, which can impact how companies manage their workforce. Companies like Micro-Tracers may need to adapt to these changes. For instance, Ontario court updates job contract rules affect how labor disputes are resolved.
