A dozen people across two states have fallen ill from E. coli infections tied to frozen organic blueberries sold at Publix supermarkets, prompting a recall that spans eight states. Four of those patients required hospitalization. The outbreak, first flagged by Florida health officials on July 1, 2026, has drawn federal investigators to a single foreign processor and a single lot of 10-ounce bags still sitting in home freezers with a best-by date nearly two years away.
Twelve illnesses and a fast-moving federal response
The Florida Department of Health notified CDC partners on July 1 after patient interviews pointed to one product: GreenWise Organic IQF Frozen Blueberries purchased at Publix. Within days, Publix conducted an internal stop sale, pulling the product from shelves before a formal recall was announced. The CDC issued a food safety alert confirming 12 confirmed cases, four hospitalizations, and zero deaths in two states.
The speed of that sequence matters. Fewer than a week elapsed between the state health department’s notification and the company-initiated recall. Per the CDC, the recall was issued July 3, 2026, though the FDA’s recall index lists the posting date as July 6, 2026. That three-day gap likely reflects the difference between the company’s internal recall decision and the FDA’s formal publication of the notice, but neither agency has explained the discrepancy on the record.
The recalled product was manufactured by Frutas y Hortalizas del Sur S.A., a processor based outside the United States. According to the FDA, the specific item is a 10-ounce package bearing lot code 60401 and a best-by date of Feb. 9, 2028. That distant expiration date means affected bags could remain in consumer freezers for more than a year if buyers miss the recall notice. The product was distributed to Publix stores across eight states, though neither the FDA nor Publix has published the full list of those states or individual store locations.
What the O145 strain and a single lot code reveal
The contamination involves E. coli O145:H28, a Shiga toxin-producing strain that can cause severe kidney complications, particularly in young children and older adults. Symptoms commonly include severe stomach cramps, diarrhea that can become bloody, vomiting, and low-grade fever. While most healthy adults recover within a week, some infections progress to hemolytic uremic syndrome, a form of kidney failure that can be life-threatening without prompt medical care.
Unlike the more commonly reported O157:H7 strain, O145 infections are harder to detect with some standard laboratory screening methods, which raises the possibility that the 12 confirmed cases represent an undercount. People who experienced short-lived gastrointestinal illness after eating the blueberries may never have sought testing, and physicians may not always order the more specific assays required to identify non-O157 strains.
The single lot code, 60401, narrows the contamination window to one production run at Frutas y Hortalizas del Sur S.A. That concentration suggests the failure occurred at a discrete point in the supply chain rather than through a systemic breakdown across multiple harvests or processing lines. One plausible explanation centers on post-harvest wash water, a known contamination vector for frozen produce. If wash water used during the individually quick frozen (IQF) process carried the O145 strain, every berry passing through that cycle on the affected production day would have been exposed.
Another possibility involves cross-contamination from equipment or surfaces that were inadequately sanitized between lots. IQF systems move fruit along belts, chutes, and sorting tables; a single contaminated batch can leave behind bacteria that persist in hard-to-clean areas. Without detailed findings from on-site inspections, it remains unclear whether the breakdown stemmed from water quality, equipment hygiene, or an upstream problem at the farm level.
The FDA has opened a formal traceback and facility investigation, summarized on its outbreak investigation page. There, regulators note that patient interviews consistently identified frozen GreenWise organic blueberries from Publix as the leading food item consumed before illness. That language stops short of declaring the product the definitive source, a distinction that reflects the ongoing nature of the traceback and the need for laboratory confirmation from product samples.
Gaps in the traceback and what investigators still do not know
Several questions remain open. Federal investigators have not published whole-genome sequencing matches that would definitively link the clinical isolates from patients to bacteria found on or in the recalled blueberries. Without that genetic confirmation, the epidemiological link rests on interview data and purchasing records. While such data can be strong, especially when multiple patients report the same specific brand and product, it does not fully rule out other foods that may have been consumed around the same time.
The FDA has also not named the specific farm or farms that supplied berries to Frutas y Hortalizas del Sur S.A. for the affected lot, leaving the upstream contamination point unresolved. In outbreaks tied to fresh or frozen produce, contamination can occur at several stages: in the field through irrigation water or animal intrusion, during harvest and transport, or at the processing facility. Identifying the precise node in that chain is critical for preventing recurrence, but such details often emerge only after lengthy international coordination and review of shipping and production records.
The eight-state distribution footprint has been referenced repeatedly by federal agencies and public health researchers, but the full list of states has not appeared in any primary recall document reviewed for this report. That omission complicates the recall’s reach: consumers in Publix’s operating territory who bought store-brand frozen blueberries have no easy way to confirm whether their state is included without checking the lot code on the bag itself. Georgia’s Department of Agriculture reposted the recall alert for consumers in that state, signaling that at least one of the eight distribution states has taken independent action to amplify the warning.
Investigators also have not disclosed whether any unopened bags from consumer homes or retail distribution centers have tested positive for E. coli O145:H28. Positive product tests would strengthen the case for the blueberries as the outbreak source and could help narrow the contamination mechanism, depending on where in the bag or production run bacteria are found. For now, regulators are operating on a precautionary basis, assuming that all bags from lot 60401 pose a potential risk.
What consumers should do now
Anyone who has a 10-ounce bag of GreenWise Organic IQF Frozen Blueberries should check the back panel for lot code 60401 and a best-by date of Feb. 9, 2028. If both the brand and codes match, health officials advise not eating the product under any circumstances. The safest option is to throw the blueberries away in a sealed bag or container so that children, pets, or wildlife cannot access them.
Consumers can also return the recalled product to Publix for a refund, according to the company’s internal communications summarized in the FDA’s recall notice. Whether discarded or returned, the bag should be handled carefully. After disposing of the blueberries, people should wash their hands thoroughly with soap and warm water for at least 20 seconds and clean any surfaces, bowls, or utensils that may have come into contact with the frozen fruit.
Those who ate the recalled blueberries should monitor for symptoms of E. coli infection for up to 10 days, the typical incubation period. Anyone who develops severe stomach cramps, bloody diarrhea, or signs of dehydration should seek medical care and mention the potential exposure to frozen blueberries from Publix. Clinicians can then order appropriate stool tests and, if necessary, notify local health departments, which helps refine outbreak counts and guides further public health action.
Public health officials emphasize that frozen fruit remains generally safe, and no other GreenWise blueberry lot codes or sizes are currently included in the recall. Still, the episode underscores the importance of checking lot codes and best-by dates when recalls are announced, especially for long-shelf-life items that can linger in freezers for years. As the investigation continues, regulators may update case counts or expand the scope of implicated products; consumers concerned about exposure can follow CDC and FDA updates for the latest guidance.
