A recall notice from Publix and a joint FDA–CDC investigation have plenty of shoppers staring at their freezer bags this week. An E. coli O145:H28 outbreak has been linked to GreenWise Organic Frozen Whole Blueberries and Whole Mixed Berries sold in eight states, with 12 illnesses and 4 hospitalizations reported so far. For people with gout, this story contains a genuinely important question: are frozen blueberries still a good choice? The short answer is yes — with one important caveat about what freezing does and does not do to bacteria.
Why Frozen Blueberries Are a Gout-Friendly Staple
Start with the food, not the headline. Blueberries are naturally low in purines, so they carry none of the uric acid burden associated with organ meats, shellfish, or red meat. They are also low in fructose compared with many other fruits — relevant because fructose is the sugar most closely tied to higher uric acid levels in prospective research (Choi 2008, BMJ). For these two reasons alone, blueberries appear on most gout-friendly fruit lists, including ours at low-fructose fruits.
Blueberries are also rich in anthocyanins, the plant pigments that give them their deep blue color. The most famous gout research on this family of compounds involves cherries: in a study of 633 people with gout, cherry intake over a two-day period was associated with a 35% lower risk of gout attacks compared with no cherry intake (Zhang 2012). Berries are not cherries, but the shared anthocyanin chemistry is one reason berries are routinely grouped with anti-inflammatory foods in gout-focused diet resources.
And there is a practical layer that matters for steady habits: frozen berries are affordable, available year-round, and easy to keep on hand, which removes the biggest barrier to eating fruit daily. For people managing a chronic condition, consistency in a healthy diet beats occasional perfection — and frozen berries make consistency much easier to achieve.
The Catch: Frozen Does Not Mean Sterile
Here is the food-safety reality behind the recall. Freezing stops or dramatically slows the growth of microorganisms, but it does not reliably kill them. E. coli can survive for long periods at freezer temperatures — freezing essentially puts the bacteria into suspended animation. When berries are contaminated before freezing, as is believed to have happened in this outbreak, the bacteria simply ride along inside the bag, alive and waiting.
The outbreak strain, E. coli O145:H28, is one of the Shiga toxin-producing strains that can cause severe stomach cramps and bloody diarrhea, and occasionally more serious complications. The implicated products were GreenWise Organic Frozen Whole Blueberries and GreenWise Organic Frozen Whole Mixed Berries sold at Publix stores in eight states, with the fruit sourced from Frutas y Hortalizas del Sur S.A. in Chile. The recall was first issued July 3 and expanded July 29, when Publix recalled all lots of the affected products.
The practical meaning: "frozen" is a storage method, not a sterilization step. That is not a reason to stop eating frozen fruit — it is a reason to check labels, follow recalls, and handle frozen produce with the same common sense you already apply to fresh produce. The label "frozen" is about texture and shelf life, not a promise that microbes were eliminated.
How to Check the Recall and Handle Frozen Berries Safely
Check your freezer first. The recalled items are specifically GreenWise Organic Frozen Whole Blueberries and GreenWise Organic Frozen Whole Mixed Berries. Look for the brand name, the product name, and any lot or date codes printed on the bag, then compare them against the recall notice on the FDA website. If your bag matches, do not eat it — discard it or return it to the store, then wash your hands and wipe down the freezer drawer where it was kept.
For all frozen fruit, a few good habits keep risk low: wash your hands before and after handling packages; thaw berries in the refrigerator rather than on the counter; and if you are feeding young children, older adults, or anyone with a weakened immune system — or if you are simply cautious — cook berries before eating them. Heat reliably kills E. coli, so berries simmered into a sauce, baked into muffins, or stirred into hot oatmeal carry essentially no bacterial risk. Raw-frozen smoothies are fine for most healthy adults when the product is not part of a recall.
The Bottom Line for People With Gout
A recall is about specific products and specific lots, not about an entire food category. The E. coli outbreak does not change the nutritional case for frozen berries in a gout-friendly diet: they remain low in purines, low in fructose, and a practical way to get the same anthocyanins studied in cherry research.

So keep your freezer stocked — just shop with your eyes open. Check recall notices when you buy frozen fruit, cook it when you want zero doubt, and let the rest of your choices follow simple logic: variety, moderation, and good handling. The same reasoning applies to other frozen fruit: an occasional recall makes careful shopping worthwhile, but it should not push you away from a category that helps you meet fruit goals cheaply and conveniently all year. If you want to compare other frozen-friendly, low-purine options side by side, you can search "low-fructose fruits" in the FoodCanEat database.
Frequently Asked Questions
Do I need to avoid all frozen blueberries?
No. This recall is limited to GreenWise Organic Frozen Whole Blueberries and Whole Mixed Berries sold at Publix, tied to specific lots from one supplier. Check the brand name and the lot or date codes on your bags against the FDA recall notice before eating anything from your freezer. Other brands — including store brands and generic frozen blueberries — were not part of this outbreak. Freezing does not sterilize food, so general safe-handling rules still apply, but you do not need to clear frozen fruit out of your diet.
Can E. coli survive freezing?
Yes. Freezing slows bacterial activity but does not kill most bacteria, including E. coli, which can remain viable for months at freezer temperatures. When contaminated fruit is frozen, the bacteria survive in the bag and can cause illness once the berries are thawed and eaten. Thorough cooking kills E. coli, which is why cooked berries — in sauces, baked goods, or oatmeal — are the lowest-risk option whenever you have any doubt about a particular product.
Are blueberries actually good for gout?
Blueberries are naturally low in purines and relatively low in fructose, making them a sensible fruit choice in a gout-friendly diet. They also supply anthocyanins, the plant pigments linked in research on cherries to a lower risk of recurrent gout attacks (Zhang 2012). Studies like this are observational, so the honest phrasing is that berries "may help" rather than that they "prevent" flares. Either way, including blueberries alongside other low-fructose fruit is consistent with the dietary moderation emphasized in current gout guidance (ACR 2020) and the wider evidence base.
