Washington, DC -- July 23, 2026: The U.S. Food and Drug Administration (FDA) has opened a new Cyclospora outbreak investigation involving 72 epidemiologically linked illnesses, but officials have not identified the food responsible.
The new investigation, assigned FDA Reference #1392, was added to the agency's Investigations of Foodborne Illness Outbreaks table on July 22.
At this stage, these are the confirmed facts released by the FDA:
72 epidemiologically linked illnesses have been identified.
The illnesses have been assigned FDA Investigation #1392.
The product responsible has not been identified.
The FDA has initiated traceback efforts to determine a possible common source.
No recall has been issued.
No public health advisory has been issued.
What "Separate Outbreak" Actually Means
News reports have widely described Investigation #1392 as a "separate outbreak." While that description reflects how the FDA is currently managing the investigation, it should not be interpreted as proof that investigators have identified a different contaminated food.
The FDA has not announced a source for Investigation #1392.
Instead, the agency has opened a new investigation because, based on the evidence currently available, the 72 illnesses have not yet been linked to any existing Cyclospora investigation.
That is an operational classification, not a scientific conclusion.
Until investigators identify the contaminated product, several possibilities remain:
The illnesses could be linked to a completely different food.
They could ultimately be connected to an existing Cyclospora investigation.
They could involve the same product through a different supplier or distribution chain.
Investigators could later merge the investigations if evidence establishes a common source.
At this point, the FDA has not ruled in or ruled out any of those possibilities.
Investigation Continues
The FDA's public update provides little additional information beyond confirming that traceback activities are underway.
No product has been identified, no companies have been named, and no recommendations have been issued for consumers to avoid any specific food associated with Investigation #1392.
As investigators continue interviewing patients and tracing food distribution records, additional information could determine whether Investigation #1392 represents a newly identified food source or is eventually linked to another ongoing Cyclospora investigation.
For now, the only confirmed conclusion is that the FDA is investigating a cluster of 72 illnesses whose source remains unknown.
