Frozen Blueberries Sold at Publix Recalled Over E. coli. Here’s Why Freezing Didn’t Make Them Safe.

The short version: In July 2026, Frutas y Hortalizas del Sur S.A., a grower and packer based in San Carlos, Chile, recalled GreenWise Organic IQF (individually quick frozen) Blueberries because they may be contaminated with E. coli O145:H28, a toxin-producing strain that can cause serious illness. The recall is tied to an outbreak that sickened 12 people — 11 in Florida and 1 in Georgia — with four of them hospitalized, according to public health investigators. The blueberries were sold under Publix’s organic store brand, GreenWise, across eight Southeastern states. No deaths have been reported. What makes this recall worth understanding rather than just filing away: the two things most people assume protect them — that it’s frozen, that it’s organic — do nothing to stop this particular danger.

How to Check Your Freezer

Start with the bag. The recall applies specifically to GreenWise Organic IQF Blueberries in the 10-ounce size, and the identifying details are printed on the package. Look for lot code 60401 and a “Best by” date of February 9, 2028. GreenWise is Publix’s organic house brand, so this is a product people bought expecting a premium, health-conscious choice — not a store-brand bargain.

The product was distributed to Publix stores in eight states: Alabama, Florida, Georgia, Kentucky, North Carolina, South Carolina, Tennessee, and Virginia. Because the best-by date runs all the way to February 2028, these bags are not going to expire out of freezers on their own any time soon — which is exactly why a recall like this matters. A contaminated bag bought months ago can still be sitting behind the ice cream, perfectly frozen and looking completely normal.

Why Freezing Doesn’t Kill E. coli — and Cooking Isn’t the Answer Either

Here is the part that surprises most people. Freezing does not kill bacteria. According to the Centers for Disease Control and Prevention, freezing puts bacteria like E. coli into a kind of suspended animation — it stops them from multiplying, but the ones already there survive, and they wake back up when the food thaws. A blueberry that was contaminated in the field or during packing is just as contaminated after months in your freezer as the day it went in.

The natural next thought is: fine, I’ll just cook them. Heat does kill E. coli. But that logic breaks down with frozen berries for two reasons. First, frozen blueberries are almost always eaten without being cooked to a temperature high enough to kill bacteria — dropped raw into a smoothie, thawed onto yogurt or oatmeal, stirred into a bowl of cereal, or used as a topping. Second, and less obvious, is that just handling the berries can spread the bacteria to your hands, the blender, the cutting board, and the countertop before anything gets heated at all. That’s why the guidance for a contamination recall like this isn’t “cook them thoroughly” — it’s simply don’t eat them, and clean up anything they touched.

The “organic” label deserves its own note, because it’s doing a lot of quiet reassurance work here. Organic refers to how a crop is grown — the pesticides and fertilizers allowed, the farming practices used. It is not a food-safety rating and says nothing about whether a product carries harmful bacteria. Produce of any kind, organic or conventional, can pick up E. coli from contaminated water, soil, animals, or handling. A premium organic bag from a trusted grocery brand can carry the same risk as anything else on the shelf.

What E. coli O145 Actually Does

Most people who have heard of a dangerous E. coli know the name O157:H7 — the strain behind decades of headline outbreaks in ground beef, leafy greens, and more. The strain in this recall, E. coli O145:H28, is less famous but comes from the same dangerous branch of the family: it is a Shiga toxin-producing E. coli, or STEC. O145 is one of the six non-O157 STEC groups — sometimes called the “Big Six” — that U.S. public health agencies track closely precisely because they can cause the same serious illness as the more familiar O157.

According to the CDC, STEC infection usually shows up three to four days after exposure, with severe stomach cramps, diarrhea that is frequently bloody, and vomiting. Some people run only a low fever or none at all. Most recover within about a week. The danger is in the minority who don’t.

One practical note the CDC stresses: people with a possible STEC infection should generally not take anti-diarrhea medicine like loperamide (Imodium) without a doctor’s guidance, and antibiotics are often avoided too, because both can raise the risk of HUS. When in doubt, the safe move is to call a doctor rather than self-treat.

Why the Recall Came Weeks After People Got Sick

One thing that confuses a lot of readers about food recalls is the timing. In this outbreak, the reported illnesses ran roughly from mid-May to early June 2026 — but the recall didn’t become public until July. That gap isn’t a cover-up; it’s how outbreak investigations actually work.

When someone is diagnosed with an STEC infection, a sample is often sent to a public health lab, where the bacteria’s genetic fingerprint is mapped through whole-genome sequencing and uploaded to a national database. When several people in different places turn out to be infected with a nearly identical strain, investigators know they’re looking at a single outbreak rather than unrelated cases. Then comes the hard part: interviewing sick people about everything they ate weeks earlier, and tracing a common product back through the supply chain to a specific grower and lot. Only once the evidence points to a product does a recall follow. The lag is the price of getting the answer right — and it’s the reason a bag with a 2028 best-by date is being pulled now for illnesses that happened in the spring.

A Recall Is a Precaution — Not a Finding of Fault

Lawsuit Loop follows recalls carefully because the responsible way to report one is also the accurate way: tell people exactly what to do to stay safe, and describe what investigators have found without overstating it. A recall protects the public quickly. Questions of accountability — who, if anyone, is legally responsible — are answered later and separately, and they depend on facts that are still developing.

This Isn’t the First Frozen-Fruit Scare

If frozen berries feel like an unlikely culprit, they shouldn’t. The same qualities that make them convenient — picked and frozen at scale, shipped long distances, eaten without cooking — are what make them a recurring source of recalls. We covered a separate frozen berry recall over Hepatitis A contamination earlier: a different germ, a different retailer, but the same underlying lesson that freezing preserves a pathogen instead of killing it. It’s the same story that plays out with other ready-to-eat produce, from a multistate cantaloupe Salmonella outbreak to bagged salad greens.

The takeaway isn’t to fear the freezer aisle. It’s to treat a recall notice as the one moment when a normal-looking, still-frozen bag genuinely needs to go — and to know that “I’ll just heat it up” isn’t the safeguard it feels like.

Where the Law Comes In

Lawsuit Loop follows food recalls because they sit where public safety meets accountability. When contaminated food is alleged to have caused a serious illness — a hospitalization, an HUS diagnosis, lasting kidney damage — one of the questions that follows is whether the company that grew, packed, or sold the product should be responsible. People in that situation have, in some cases, pursued claims against those companies. The same kind of foodborne-illness accountability comes up in our coverage of cases like the Costco Salmonella outbreak.

Whether any particular situation supports a claim depends entirely on the specific facts — what was eaten, the medical diagnosis, and what can be shown linking the illness to the product — and nothing here is a prediction that any case would succeed or a promise of any outcome. Outbreaks involving overseas growers and store-brand supply chains can also be legally complicated, which is part of why the facts matter so much. If a serious illness has affected your family, the priority is medical care. If, after that, you want to understand your options, you can talk to a lawyer or use the free form on this page.
