A single Chilean blueberry supplier has now generated three separate U.S. product recalls across two grocery chains since early July, and federal regulators have placed its frozen blueberries on an import alert that allows shipments to be held at the border without physical testing. The pattern is what makes this story different from a routine recall notice, because it shows how long contaminated imported fruit can keep surfacing after the first illness is detected.
The outbreak strain of E. coli O145:H28 has now been confirmed in 17 people, with six hospitalizations and no deaths, according to the Centers for Disease Control and Prevention. FDA lists the cases in Florida and Georgia. Illnesses began as early as May 11, and the most recent onset recorded on the federal advisory falls in the first week of August. That is a span of nearly three months during which product from the same source stayed in circulation.
For households, the practical meaning is simple. Checking a freezer once in July was not enough, because the products under recall changed twice after that.
The Three Recalls and the Order They Arrived
The first action came on July 3, when Frutas y Hortalizas del Sur S.A. of San Carlos, Chile, recalled a single lot of frozen GreenWise Organic IQF Blueberries in 10-ounce packages, lot code 60401, sold at Publix in eight states.
On July 29, Publix went further and recalled all lots of GreenWise Organic Whole Blueberries and Whole Mixed Berries in both 10-ounce and 48-ounce sizes. That was the chain acting, not the supplier, and it followed an FDA remote regulatory assessment of the Chilean plant that raised concerns about at least one additional blueberry lot used in other GreenWise products.
On September 2, the supplier itself expanded again, adding one lot of Great Value Organic Triple Berry Blend sold at Walmart stores in 16 states. The Food and Drug Administration posted that notice on September 3 and updated its outbreak advisory the same day. Combined, the three actions cover 19 states of confirmed distribution.
Each step widened the product list without widening the illness list. Publix described its expansion as proactive, and FDA has not tied either the Publix expansion or the Walmart lot to a confirmed infection.
The Border Control Regulators Reached For
The most consequential regulatory step in this investigation has drawn less attention than the recalls. After conducting a remote regulatory assessment of the Chilean facility and collecting company records, FDA added the firm's products to Import Alert 99-35 in late July. Frozen blueberries from this supplier offered for entry into the United States may now be detained without physical examination.
That shifts where the burden of proof sits. Under normal conditions, imported produce enters unless inspectors find a problem. Under an import alert, the shipment is treated as having the appearance of a violation, and the firm must submit documentation showing it has resolved the conditions that led to the listing before entry resumes.
FDA also said it had concerns about other products from the firm that have not entered the U.S. market and communicated those concerns to the company directly. Nothing in the public record indicates that the agency has identified the specific point of contamination inside the facility.
The Distance Between a Grocery Shelf and a Chilean Packing Line
Chile is a major counter-seasonal supplier of berries to the United States, which is why a problem at one facility can appear under different brand names, in different package sizes and at different retail chains months apart.
It also explains the traceback lag. Investigators first had to link a cluster of Florida illnesses to a product, then to a supplier, then to individual lots, then to other finished goods made from those lots. The Florida Department of Health notified CDC of the illness cluster on July 1. The Walmart product was not identified until early September, roughly two months later and nearly four months after the earliest illness onset.
None of that reflects a failure to act. It reflects how long records-based tracing takes when a single ingredient moves through multiple processors and private-label brands. For readers, the takeaway is that recall lists tied to an open investigation should be treated as provisional rather than final.
The private-label structure adds a further layer. Great Value and GreenWise are store brands, which means the name on the bag identifies the retailer rather than the grower. A shopper comparing two bags from different chains has no way to know they came from the same Chilean packing line. That information exists only in supplier records, which is exactly what traceback work reconstructs.
Who Should Pay the Closest Attention Now
Households in the 19 states of confirmed distribution have the most direct reason to recheck their freezers against all three recall notices, not only the newest one. That is Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Minnesota, Mississippi, Missouri, North Carolina, Ohio, Oklahoma, South Carolina, Tennessee, Texas, Virginia and Wisconsin. FDA has cautioned that the product could have reached additional states.
The clinical risk remains concentrated. E. coli O145 causes severe cramping, diarrhea that may be bloody, and vomiting, usually starting three to four days after exposure. A minority of infections progress to hemolytic uremic syndrome, a form of kidney failure that falls hardest on young children, older adults, and people with weakened immune systems. Anyone in those groups who ate frozen berries and develops bloody diarrhea should seek care and mention the exposure, because Shiga toxin infections are managed differently from ordinary food poisoning.
FDA has said the investigation is ongoing and that additional products may be added. The next meaningful updates will come from the agency's outbreak advisory page and from CDC's case count, both of which have been refreshed roughly monthly since July.
Key Questions Answered
How many recalls has this supplier been involved in? Three actions since July 3: the original GreenWise blueberry lot, the Publix expansion to all GreenWise blueberry and mixed berry lots, and the Great Value Triple Berry Blend lot.
What is an import alert? It allows FDA to detain a firm's shipments at the border without examining each one. The firm must document that it resolved the underlying conditions before entry resumes.
Has the contamination source been identified? No. FDA has said it is working with state partners to determine the source, and the investigation remains open.
How many people are sick? Seventeen confirmed infections, six hospitalizations and no deaths, based on CDC and FDA figures published in early September. FDA lists the cases in Florida and Georgia.
Are the newer recalls linked to illnesses? No. Publix described its expansion as proactive, and the company called the Great Value action precautionary. Neither has been tied to a confirmed case.
Could this affect other brands? FDA has said additional products may be added to the advisory. Any further additions would be posted on the agency's outbreak investigation page.
Should shoppers avoid all frozen blueberries? No. The recalls cover specific brands and lot codes. Frozen berries from other suppliers are not part of this investigation.
