The FDA and USDA have not issued a uniform federal definition of ultra-processed foods, despite seeking public input more than a year ago. The FDA has missed an April deadline for developing a definition, and the agencies have not said when they will release one.
The FDA has missed an April deadline to develop a federal definition of ultra-processed foods (UPF), and the FDA and U.S. Department of Agriculture have not yet issued the uniform definition they sought public input on more than a year ago. The delay leaves consumers, food producers and policymakers without a shared federal standard for identifying which foods fall into the category.
The FDA and USDA began seeking public input through a Request for Information more than a year before the report, asking for input to help establish a federally recognized, uniform definition of UPF. The request marked a step toward a common federal description, but the agencies have not published one, according to Food Safety News.
The report says the FDA had an April deadline for coming up with a definition and has already missed it. It does not specify the exact date or terms of that deadline, explain why it was missed, or identify a revised timetable. The USDA’s role in the effort is part of the joint work described in the report; the missed deadline is specifically attributed to the FDA.
Food Safety News says defining ultra-processed foods has proved difficult. It compares the agencies’ unresolved task with the phrase “I know it when I see it,” used by U.S. Supreme Court Justice Potter Stewart in 1964 when describing a test for obscenity. That is the report’s characterization of the difficulty, not an announced standard or a statement from either agency.
Why a Federal UPF Definition Matters
A shared definition could give federal agencies a common basis for discussing and identifying UPFs. Without one, public debate and policy proposals may use the same term in different ways, making it harder for readers to tell which foods are included and to compare claims that rely on the label.
The delay also matters because a federal definition could affect how food categories are discussed in government guidance and regulation. The source report does not say that a definition would automatically change product labels, dietary advice or regulatory requirements. Those outcomes would depend on later decisions, which have not been detailed.
For consumers, the immediate point is narrower: there is not yet a uniform federal definition in the reported development. The term may appear in public discussion, but the agencies have not supplied the requested shared federal framework. Until they do, readers should be cautious about treating every use of “ultra-processed” as if it followed an agreed government classification.

How the Federal Definition Effort Began
More than a year before the October 2026 report, the FDA and USDA issued a Request for Information seeking public input on a uniform definition of ultra-processed foods. The request was intended to inform the creation of a federally recognized definition. It was a call for input, not the publication of a final standard.
By the time Food Safety News published its report on Oct. 25, 2026, the definition remained unfinished and the April deadline had passed. The article was updated on Oct. 26. Its main topic is the federal definition effort; it also includes brief updates on foodborne illness investigations, a shellfish closure in Virginia, Dutch poultry measures and a court order pausing a USDA reorganization plan. Those separate items do not establish a timetable or explain the delay in the UPF work.

What the Agencies Have Not Said
The source material does not give a reason for the missed April deadline, a new target date, or details about the agencies’ progress. It also does not say whether the FDA and USDA plan to issue a joint definition, revise their approach, or hold additional public consultations.
The report does not include direct statements from FDA or USDA officials about the delay. It therefore cannot establish how either agency currently views the work or whether a draft definition exists. The precise scope of any eventual definition—and whether it would affect labeling, guidance or regulation—also remains unconfirmed.
Awaiting a Revised Federal Timetable
The next clear development would be an update from the FDA and USDA on the status of the definition effort, including whether they will set a new deadline or describe how they are using the public input already collected. The source report gives no date for such an announcement.
Until the agencies publish a definition or provide further details, the effort remains unfinished and its timetable unclear. Any claim about what the federal definition will include, or what policy changes might follow, would go beyond the information currently reported.
Key Questions
What is the current status of a federal UPF definition?
The FDA and USDA have not issued a uniform federal definition, according to the Oct. 25 report. The agencies had sought public input more than a year earlier.
Which agency missed the April deadline?
The report says the FDA missed the April deadline for coming up with a definition. It does not give the exact terms of the deadline or explain the delay.
Why is it difficult to define ultra-processed foods?
Food Safety News says the task has proved difficult, but the supplied report does not lay out the technical or policy disagreements behind that difficulty. It uses Justice Potter Stewart’s “I know it when I see it” phrase as an analogy, not as a definition.
When will the agencies publish a definition?
No revised date is provided in the report. The FDA and USDA have not announced a timetable in the supplied source material.
Would a federal definition change food labels or regulations?
The report does not say. A shared definition could provide a common federal reference point, but any effect on labels, guidance or regulation remains unclear and would depend on later agency decisions.
