The FDA and USDA have not produced a federally recognized definition of ultra-processed foods, despite seeking public input more than a year ago. The FDA missed an April deadline, and the agencies have not said when a definition will be ready or what criteria it will use.
The Food and Drug Administration has missed an April deadline to develop a federal definition of ultra-processed foods, and the FDA and U.S. Department of Agriculture have not announced a uniform standard. The agencies solicited public input more than a year ago, but the work remains unfinished, leaving a key food category without the federally recognized definition they sought to establish.
The agencies issued a Request for Information more than a year before the October 2026 report, asking the public to weigh in as they worked toward a shared definition of ultra-processed foods, commonly abbreviated as UPF. The request was part of an effort to create a standard recognized across the federal government.
According to Food Safety News, the FDA had an April deadline to come up with a definition and missed it. The report does not give a revised deadline, explain which parts of the work remain unresolved, or say whether the agencies have selected a particular definition framework.
The development was included in the outlet’s October 25 Sunday Edition, a roundup of food-safety news. The report says the agencies have not abandoned the effort, but it does not cite a new agency statement or provide details about public submissions, internal discussions, or the next formal step.
Why a Federal UPF Standard Matters
A shared federal definition could give government agencies a common basis for referring to ultra-processed foods. Without one, the FDA and USDA have yet to establish the uniform standard their public-information request was intended to support. The missed deadline means that work is not complete on the timetable reported.
The issue may matter to consumers, researchers, food producers, and public officials who encounter the term in discussions of food and health. A government definition could help make references to the category more consistent, but the source report does not establish what the eventual definition would mean for food labels, regulation, or dietary guidance. Those possible effects should not be treated as confirmed policy changes.
For now, the concrete development is limited: the agencies sought public input, the FDA missed its April target, and no shared federal definition has been announced. The consequences of the delay depend on decisions the agencies have not yet made public.

How Federal Definition Work Began
The FDA and USDA began the process by issuing a Request for Information more than a year before October 2026. The request invited public input to help the agencies establish a federally recognized, uniform definition. The report does not provide the request’s publication date, summarize the comments, or describe a formal proposal released afterward.
Defining UPFs has proved difficult, according to the source report. It offers no detailed account of the competing approaches or specific disagreements behind the delay. The report uses a comparison to Justice Potter Stewart’s 1964 phrase “I know it when I see it” to convey the challenge, not as an official description from either agency. No such wording has been attributed to the FDA or USDA.
The Sunday Edition also covered separate food-safety developments, but those reports do not change the status of the UPF definition effort. The relevant timeline here is the agencies’ public request for input, the missed April deadline, and the absence of an announced replacement date as of October 25, 2026.
“I know it when I see it.”

Unanswered Questions on the Definition
The report does not say why the April deadline was missed, whether the agencies have agreed on a timetable, or when they might release a draft or final definition. It also does not identify the criteria under consideration or explain how the FDA and USDA would resolve differences in approach, if any.
It remains unclear what practical effect a federal definition would have. The source does not say whether it would be used in labeling, regulation, dietary guidance, research, or another area. No specific policy change tied to a definition is confirmed in the report.
The agencies’ continued participation in the effort is described, but no new agency announcement is included. Until they provide further details, the status and scope of the project remain uncertain beyond the missed deadline and lack of a published standard.
Awaiting an Agency Timetable
The next concrete step would be an update from the FDA and USDA explaining the status of their work and any revised schedule. The source report identifies no upcoming publication, meeting, or other milestone, so a release date cannot be stated.
Readers looking for a definitive federal standard will need to wait for the agencies to publish a definition or describe the next stage of the process. Until then, the confirmed position is that the April deadline passed and a uniform federal definition of UPFs has not been announced.
Key Questions
What does UPF mean?
UPF is an abbreviation for ultra-processed foods. The report concerns efforts to create a uniform federal definition; it does not provide a definitive list of which foods fall into the category.
Have the FDA and USDA published a shared definition?
No shared, federally recognized definition had been announced in the report published on October 25, 2026.
What deadline did the FDA miss?
The FDA missed an April deadline to come up with a definition. The report does not specify a revised deadline.
What happens next?
The agencies have not announced a next milestone in the source report. A timetable or further explanation would need to come from the FDA and USDA.
