The FDA and USDA have not established a federally recognized definition of ultra-processed foods, more than a year after requesting public input. The Sunday Edition report says the agencies have not adopted a definition, while the source does not provide a new deadline or explain what has delayed the work.

The FDA and USDA have not established a uniform federal definition of ultra-processed foods, more than a year after asking the public for input, according to a Food Safety News report published October 25. The delay leaves consumers, food producers and policymakers without a shared federal standard for identifying foods in this category; the report says the FDA had already missed an April deadline for producing a definition.

The agencies issued a Request for Information more than a year ago to gather public input as they worked toward a federally recognized, uniform definition of ultra-processed foods (UPF). The report describes that effort as unresolved: neither agency had announced a completed definition by the report’s publication.

The report says the task has proved difficult, but does not specify which scientific, regulatory or policy disagreements are holding up the work. It also does not identify a revised timetable. The missed April deadline applies to the FDA’s work on producing a definition, according to the report; the supplied material does not give the original deadline date or further details about its scope.

Rather than adopting a threshold along the lines of “I know it when I see it,” the agencies have not announced any official standard, the report says. That wording echoes a 1964 remark by Supreme Court Justice Potter Stewart about obscenity. It is used here as a description of the challenge, not as a formal test or a definition adopted by the FDA or USDA.

The developmentA Food Safety News report published October 25 says the FDA and USDA still have not set a uniform federal definition of ultra-processed foods after soliciting public input more than a year ago.

Why a Federal UPF Standard Matters

A common federal definition could give government agencies a consistent basis for discussing and classifying ultra-processed foods. Without one, different institutions or researchers may use different criteria when referring to UPF, making comparisons and public communication harder to interpret. The report confirms the absence of a federal definition, but does not detail how that gap is affecting specific regulations or programs.

The issue also concerns consumers and food businesses because a government-recognized category could shape how food products are described in public discussion and policy. At this stage, however, the report does not say that a definition would automatically change product labels, dietary guidance or food-safety rules. Those possible effects would depend on what the agencies eventually define and how they choose to use it.

The Agencies’ Request for Public Input

The current effort began with an FDA and USDA Request for Information seeking public views on a uniform definition. Such a request gathers input; it is not itself a final rule or a completed definition. More than a year later, the agencies had yet to produce the outcome described in the report.

The Sunday Edition report also places the UPF issue alongside other developments in food safety and federal policy. Those include reported foodborne-illness investigations, a shellfish-harvesting closure in Virginia and a court stay involving a USDA reorganization plan. They are separate items, not evidence that the UPF definition process is linked to those events.

The report’s headline and opening note frame the missing definition as an overdue federal action, with the FDA having missed an April deadline. The source material does not provide a detailed history of that deadline, a summary of the public comments, or the agencies’ response to the delay.

“The FDA has already missed last April’s deadline for coming up with a definition.”

What the Agencies Have Not Explained

The source does not say why the definition is delayed, whether the FDA and USDA disagree about its scope, or what criteria they are considering. It also gives no revised release date and does not report whether the agencies have published a response to the public comments.

It remains unclear what foods would fall within any eventual definition and whether the agencies plan to use it for labeling, guidance, research or other policy purposes. The report establishes that no uniform federal definition had been issued at the time of publication; it does not establish that the agencies have abandoned the effort.

Awaiting an Agency Definition

The next clear milestone would be an announcement from the FDA or USDA explaining the status of the work, the criteria under consideration and a timetable for a proposed or final definition. The source material does not report a scheduled announcement or another formal deadline.

Until the agencies publish further details, the Request for Information remains the stated basis for the federal effort, and the definition remains outstanding. Any claims about the eventual scope or policy consequences should be treated as unsettled until the agencies describe their approach.

Key Questions

Have the FDA and USDA defined ultra-processed foods?

No. The Food Safety News report says the agencies had not established a uniform federal definition as of its October 25 publication.

What did the agencies do to develop a definition?

More than a year earlier, the FDA and USDA issued a Request for Information to solicit public input on a federally recognized, uniform definition.

What deadline was missed?

The report says the FDA missed an April deadline for coming up with a definition. The supplied source material does not give the original deadline’s exact date or a replacement date.

Why is the definition delayed?

The report says defining UPF has proved difficult but does not explain the specific scientific or policy issues behind the delay. The agencies’ reasoning is not detailed in the supplied material.

When will a federal definition be released?

No revised release date is provided. The next step depends on the FDA or USDA sharing an updated timetable or publishing its proposed approach.
