According to a heavily redacted report just released, the FDA issued an import alert requiring border holds on an unnamed produce item linked to a deadly Listeria outbreak that stretched from April 2024 through at least June 2025.

The Food and Drug Administration investigated the outbreak with the Centers for Disease Control and Prevention, but did not release details about the businesses behind the specific foods linked to the outbreak that sickened 27 people, with 25 hospitalizations and one death reported. The agencies still have not reported what states the patients lived in of what their ages were.

According to the Executive Incident Summary Abstract released this week, the FDA said it could not identify the source of the outbreak, but also said “based on positive laboratory findings and related WGS of the (redacted) linked to (redacted), (redacted) remains the suspect vehicle for this outbreak.”

At least one of the outbreak patients became ill after a restaurant exposure.
