Four people have been hospitalized after eating frozen blueberries contaminated with E. coli, part of a widening outbreak tied to a product recall at Publix supermarkets in eight states. The CDC says the true number of people sickened is likely far higher than the dozen cases reported so far.
The recalled product, GreenWise Organic frozen blueberries sold in 10-ounce beige bags, tested presumptively positive for E. coli O145, a potentially life-threatening strain. The berries were grown by Frutas y Hortalizas del Sur SA, a Chile-based company, and sat on Publix shelves from May 11 through June 5, the same window during which all 12 reported illnesses occurred.
Patients range in age from 2 to 88 years old. Eleven of the 12 cases are in Florida. One is in Georgia. Of nine people interviewed by investigators, seven confirmed they had eaten the frozen blueberries.
Federal investigators are treating this as a multistate event, even though confirmed cases have so far surfaced in only two of the eight states where the product was sold. The other six, Alabama, Kentucky, North Carolina, South Carolina, Tennessee, and Virginia, have reported no cases yet, but the CDC has warned that the picture is incomplete.
The agency stated plainly that the outbreak likely extends beyond current numbers:
"The true number of sick people in this outbreak [is] likely much higher than the number reported, and this outbreak may not have been limited to the states with known illnesses."
That warning matters. E. coli typically sickens people between two and eight days after exposure, and it can take three to four weeks to determine whether a sick person is connected to a specific outbreak or recall. Consumers who bought the blueberries weeks ago may not yet know they are part of the problem.
The CDC and FDA, along with public health officials in several states, are jointly collecting data. But neither agency has confirmed the presumptive positive E. coli test result with final lab analysis, at least not publicly. The contamination source also remains unidentified. The CDC's epidemiologic statement said only that the frozen blueberries "may be contaminated" and "may be making people sick."
Frutas y Hortalizas del Sur SA issued the recall after receiving reports of stomach illnesses from customers and getting a presumptive positive E. coli result from testing. In its recall notice, the company offered a single line of reassurance:
"Food safety remains a top priority for Frutas y Hortalizas S.A."
That is the entirety of the company's public comment. No explanation of how the contamination occurred. No description of corrective steps beyond pulling the product. No timeline for a root-cause investigation.
Publix, for its part, announced the recall and told consumers the berries were available in stores between May 11 and June 5. The recalled bags carry a best-before date of February 9, 2028, and lot code 60401, printed on the barcode. Shoppers have been urged to throw the product away immediately or return it to any Publix store for a full refund.
Neither Publix nor the grower has disclosed which two states the four hospitalizations occurred in, or the ages and conditions of those patients.
Consumers often assume that frozen food is safe by default. E. coli complicates that assumption. The bacteria stop growing below 45.5°F but can survive temperatures as low as negative 112°F. Freezing does not kill the pathogen, it merely pauses it. Once the berries thaw in a warm environment, the bacteria reactivate.
Contamination can occur when fruits are treated with water containing animal feces, though investigators have not confirmed that as the mechanism in this case. The source of the E. coli remains an open question, one that federal regulators have yet to answer publicly.
Roughly 90,000 Americans are sickened by E. coli every year. Around 100 die from the infection annually in the United States and the United Kingdom combined. E. coli O145, the strain identified here, is less commonly discussed than the well-known O157 strain, but it belongs to the same family of Shiga toxin-producing bacteria that can cause kidney failure, particularly in young children and the elderly.
The age range of patients in this outbreak, 2 to 88, suggests the most vulnerable populations are already being hit.
Several basic questions remain unanswered. Investigators have not disclosed the exact date the recall was issued, referring to it only as "earlier this month." They have not said whether any cases have emerged in the six states beyond Florida and Georgia where the product was sold. And they have not confirmed whether the presumptive positive lab result has been upgraded to a confirmed finding.
The FDA's ability to manage food safety investigations has come under fresh scrutiny in recent months. The agency has faced leadership turmoil and the departure of senior officials, raising questions about whether its regulatory infrastructure is keeping pace with the demands placed on it.
Meanwhile, the broader conversation about food safety and what Americans actually consume has gained political traction. The Make America Healthy Again movement has pushed food quality and transparency to the center of Republican primary debates, with candidates running explicitly on the promise of cleaner food and stronger accountability from producers and regulators alike.
Those political arguments tend to feel abstract, until a two-year-old and an 88-year-old end up sick from the same bag of frozen fruit.
The guidance is straightforward. Anyone who purchased GreenWise Organic frozen blueberries in a 10-ounce beige bag with lot code 60401 and a best-before date of February 9, 2028, should not eat them. Throw them away or return them to Publix for a refund.
In similar previous recall situations, consumers have also been advised to discard other foods that may have come into contact with the contaminated product and to thoroughly clean freezer surfaces. Anyone experiencing symptoms, severe stomach cramps, diarrhea, or vomiting, within two to eight days of consuming the berries should contact a healthcare provider and mention the recall.
The regulatory framework governing food imports and safety standards continues to face pressure from multiple directions, including ongoing debates over federal health policy that test how aggressively agencies act to protect consumers.
Twelve people sick, four hospitalized, a Chilean grower offering boilerplate, and two federal agencies still collecting data. The berries sat on shelves for nearly a month. Somewhere between the farm in Chile and the freezer aisle in Florida, the system that is supposed to catch this kind of thing didn't, and the people paying the price are the ones who trusted it.
