The FDA has put its most serious warning on frozen blueberries and mixed berries sold at Publix, classifying a summer recall as Class I because the fruit may be carrying E. coli. That top-tier label means the agency believes there is a real chance these berries could make someone seriously sick or worse. The classification landed in mid-August, weeks after the products were already pulled from shelves.
Four GreenWise organic products are named: Whole Blueberries in 10-ounce and 48-ounce bags, and Whole Mixed Berries in the same two sizes. If you shopped at Publix this year and tossed a bag of these in the freezer, this one is worth a closer look. Frozen fruit tends to sit in the back of a freezer for months, long after the news cycle moves on.
What a Class I warning really means
The FDA sorts recalls into three buckets. Class III is for minor stuff, like a labeling mistake that won’t hurt anyone. Class II covers problems likely to cause a temporary or reversible illness and nothing worse. Class I sits at the top, and the agency saves it for cases where there is a reasonable chance the product could cause serious harm or death. Salmonella and E. coli outbreaks are the classic examples, and so are undeclared allergens.
The agency usually hands out a Class I label after finishing a full risk review. That is what happened here. The berries were already off the shelves, but the review confirmed how serious the threat was. Class I does not mean every bag is dangerous or that everyone who eats a berry gets sick. It means the risk is high enough that the government wants these products gone, not washed and eaten.
The bug behind the recall
The strain in question is E. coli O145:H28, a Shiga toxin-producing type. In plain terms, it can bring on severe stomach cramps, diarrhea, and vomiting. In the worst cases, the toxin damages the intestinal lining and can lead to a form of kidney failure. Young kids, adults over 65, and anyone with a weakened immune system tend to have the hardest time with it.
As of the CDC’s late-July update, 12 people had gotten sick from the outbreak strain and four had ended up in the hospital. No deaths have been reported. Eleven of the illnesses were in Florida and one was in Georgia. The people who got sick started showing symptoms between May 11 and June 5, which means folks were already ill weeks before anyone announced a recall.
How to check your freezer
Match the name, the bag size, and the UPC on the package. The four products are GreenWise Organic Whole Blueberries 10-ounce (UPC 41415-06453), Organic Whole Blueberries 48-ounce (UPC 41415-12053), Organic Whole Mixed Berries 10-ounce (UPC 41415-06753), and Organic Whole Mixed Berries 48-ounce (UPC 41415-12153). The recall now covers all lots of all four, so you don’t need to hunt for a specific batch code.
Do not bother hunting for a Best By date. The narrower recall back in July singled out one lot code, but the current one covers every lot of all four products, whatever date is printed on the bag. If you dumped the berries into a container or a freezer bag and can’t tell anymore which brand they came from, the safest move is to throw them out. Guessing is not worth it. Washing the berries under the faucet won’t fix the problem either, since rinsing can’t reliably remove this kind of contamination.
Just how much fruit got pulled
The scale is large. A total of 182,094 bags were recalled, which works out to more than 345,000 pounds of frozen fruit. The 48-ounce Mixed Berries made up the biggest chunk at 60,320 bags. The 10-ounce Blueberries followed at 44,994 bags, then the 48-ounce Blueberries at 37,260, and the 10-ounce Mixed Berries at 39,520.
That is a lot of product spread across a lot of kitchens. The FDA has pointed out that recalled fruit could have traveled past the states where it was sold. Someone might have bought a bag on a trip to Florida and driven it home to another state. So even if you live outside the shipping zone, a quick freezer check doesn’t hurt.
Where the berries were sold
The berries shipped to Publix stores in eight states, all in the Southeast: Alabama, Florida, Georgia, Kentucky, North Carolina, South Carolina, Tennessee, and Virginia. These were sold only under the GreenWise label at Publix, so this isn’t a warning against every frozen blueberry on the market or every GreenWise item. It’s these four specific bags.
The timeline stretches back further than most shoppers realize. Publix quietly stopped selling the products at the end of June, before any public notice went out. On July 3, the supplier recalled a single lot of 10-ounce blueberries. Then on July 29, Publix widened it to all lots of all four products. The mid-August Class I classification was the final step, locking in the highest risk rating.
The trail leads back to Chile
The blueberries came from Frutas y Hortalizas del Sur S.A., a supplier based in San Carlos, Chile. The outbreak first came to light on July 1, when the Florida Department of Health flagged a cluster of E. coli cases to the CDC. Interviews with sick people kept pointing at the same thing. Seven of nine people asked said they’d eaten frozen blueberries, and five named the GreenWise organic berries from Publix.
Florida investigators passed their findings to Publix headquarters, and the retailer moved fast on an internal stop sale. The FDA has since placed the Chilean supplier on an import alert. That gives border inspectors the power to hold future shipments from the company without physically inspecting each one first. It is a way of keeping suspect product out of stores while the investigation continues.
What to do if you have a bag
Don’t eat them. Publix says you can throw the berries away or bring them back to the store for a full refund. If you already moved the fruit out of its original bag, get rid of it rather than trying to figure out whether it’s part of the recall. The CDC also says to clean and sanitize anything the berries touched, like bowls, blenders, and countertops, with hot soapy water or a run through the dishwasher.
Do not try to cook your way out of this one. Neither the FDA nor the CDC offers heating as an option here, and there is no safe cooking temperature published for fruit the way there is for ground meat. Both agencies say the same thing: discard the berries or take them back. Anyone who already ate them should keep an eye out for symptoms, which the CDC says usually start three to four days after exposure, though the FDA notes they can appear anywhere from a couple of days up to nine days later. Call a doctor if you feel sick.
Questions can go to Publix Customer Care at (800) 242-1227, open 8:30 a.m. to 5 p.m. Eastern, Monday through Friday. The investigation is still open, so the case count could change as more information comes in.
A busy stretch for the FDA
The berry warning didn’t come out of nowhere. It landed in a busy stretch for food safety regulators: the same month the berries were classified Class I, so was a recall of nearly 1.6 million dozen eggs over salmonella. Whether that adds up to a trend is a separate question. The U.S. PIRG Education Fund, a consumer advocacy group that tracks recalls, counted 320 food recalls in 2025 against 296 in 2024, and has said it does not yet see evidence that recalls are climbing this year.
For now, the practical takeaway sits in your own freezer. Pull out any GreenWise organic blueberries or mixed berries you bought at Publix, check the bag against the list, and get rid of them if they match.
