The repeal of 21 CFR 74.250 took effect. It was Orange B's only authorised use, so the dye now has no colour additive listing in the United States. The Electronic Code of Federal Regulations shows the section removed as of this date, and no stay of the order has been published.tag:foodadditiveindex.com,2026-07-23:event/US/orange-b/phase_out_announcedFDA revokes the Orange B listing, effective 8 September 20262026-07-23T00:00:00ZUnited States, 2026-07-23. The final order at 91 FR 46276 repeals 21 CFR 74.250. FDA's records show Orange B was last batch certified in 1978 and that no certification had been requested since; because a certified colour additive may not be used without certification, FDA concluded the use had been abandoned and the listing was outdated and unnecessary. This was not a safety finding: FDA said the safety of synthetic colour additives in general was outside the scope of the action. Objections were due by 24 August 2026.tag:foodadditiveindex.com,2025-09-17:event/US/orange-b/review_openedFDA proposes removing the Orange B listing as abandoned2025-09-17T00:00:00ZUnited States, 2025-09-17. The proposed order at 90 FR 44786 would repeal 21 CFR 74.250, which permitted Orange B for one use only: colouring the casings or surfaces of frankfurters and sausages, at up to 150 parts per million. FDA said certification data showed Orange B had not been certified for use in food marketed in the United States since 1978, so the authorised use appeared to have been abandoned. Comments were invited until 17 October 2025.
