The Food and Drug Administration has assigned its most serious risk classification to the recall of GreenWise organic frozen blueberries and mixed berries sold at Publix, a designation the agency reserves for products where exposure could reasonably cause serious health consequences or death. The Class I classification was posted on August 18 in the agency's enforcement reports, about three weeks after Publix expanded the recall to cover all lots.
Twelve people infected with the outbreak strain have been reported in two states, Florida and Georgia, according to the CDC outbreak page. Four have been hospitalized. No deaths have been linked to the outbreak.
The classification does not mean anything new was found in the berries. It means the FDA completed its own hazard assessment of a recall the company had already initiated, and reached the most severe conclusion available to it.
The Difference Between the Three Recall Classes
Most people encounter recalls as a single undifferentiated category of bad news. The FDA does not treat them that way, and the distinction is useful.
A Class I recall applies when there is a reasonable probability that use of or exposure to a violative product will cause serious adverse health consequences or death. Class II covers products that may cause temporary or medically reversible health effects, or where the probability of serious consequences is remote. Class III covers products unlikely to cause any adverse health consequence, typically labeling or quality violations.
The classification is assigned by the agency after a recall begins, which is why it can appear weeks later. That timing confuses people who assume a delayed classification signals a new discovery. It usually signals the completion of a review that was always going to happen.
For a consumer, the practical meaning of Class I is narrow but real. It is the agency's judgment that this is not a precautionary label problem. It is a product that could seriously hurt someone.
What Is Actually Under Recall Now
The scope is broader than the original notice, and that is the detail most likely to be missed by anyone who checked their freezer in July.
Publix is recalling all lots of four products, according to the FDA recall notice: GreenWise Organic Whole Blueberries in 10-ounce and 48-ounce sizes, and GreenWise Organic Whole Mixed Berries in the same two sizes. The UPCs are 41415-06453, 41415-12053, 41415-06753, and 41415-12153. The enforcement reports describe the affected code information as all products with an expiration date prior to February 9, 2028.
The earlier July action, issued by the Chilean supplier Frutas y Hortalizas del Sur, covered only 10-ounce blueberries with a single lot code, 60401. MedicalDaily previously reported on that original lot-specific recall. Anyone who checked a lot code then and concluded their bag was fine needs to check again, because lot codes no longer determine whether a bag is covered.
The berries went to Publix stores in Alabama, Florida, Georgia, Kentucky, North Carolina, South Carolina, Tennessee, and Virginia. Publix placed an internal stop sale on the products at the end of June, and they remain unavailable for sale.
Why Frozen Recalls Outlast the News Coverage
A recall on lettuce resolves itself. The product spoils, the shelves clear, and the exposure window closes on its own. Frozen fruit does not behave that way.
A bag bought in June sits in a freezer through the summer, gets used a handful of times in smoothies, and can easily still be there at Thanksgiving. An expiration date well over a year out gives a household no natural prompt to look. Freezing does not kill E. coli. It suspends the bacteria, so a portion blended in October carries the risk it carried in June.
Frozen berries also tend to be decanted. People pour a bag into a container, or work through it in a resealable pouch that no longer displays the UPC. Once packaging is discarded, verification becomes guesswork. MedicalDaily has previously reported on how poorly frozen food recalls reach consumers for exactly this reason. The FDA's guidance is the same: if you froze the product without its original packaging and cannot tell whether it is part of the recall, throw it away.
Who Faces the Most Serious Risk
E. coli O145:H28 is a Shiga toxin-producing strain, the same broad category as O157:H7. Illness typically brings severe stomach cramps, diarrhea that is often bloody, and vomiting. CDC says symptoms usually start three to four days after swallowing the bacteria, and the FDA outbreak investigation notes that onset can range from a few days up to nine days.
Most people recover without treatment in five to seven days. The complication that drives the Class I designation is hemolytic uremic syndrome, a form of kidney failure that can be life-threatening. Young children, older adults, and people with weakened immune systems face the highest risk of developing it.
Do not eat the product even if it has already been thawed, and do not eat it after cooking. Discard it in a sealed bag or return it to any Publix for a full refund. Wash and sanitize any container, blender, or surface the berries touched.
Someone who ate these berries and has no symptoms does not need testing or precautionary treatment, but should watch for symptoms through the incubation window. CDC advises calling a clinician for diarrhea with a fever above 102 degrees, diarrhea lasting more than three days without improvement, bloody diarrhea, vomiting that prevents keeping liquids down, or signs of dehydration. Decreased urine output, pale skin, unexplained bruising, or confusion can indicate hemolytic uremic syndrome and warrant emergency care. Antibiotics are generally not recommended for this type of E. coli infection and can worsen outcomes, which is a reason to see a clinician rather than self-treat.

Key Questions Answered
What changed this week? The FDA assigned the recall a Class I classification, its highest risk level, in enforcement reports posted August 18. The recall itself began earlier.
Does Class I mean something new was found? No. It reflects the agency's completed hazard assessment of a recall the company had already initiated. Classification routinely follows a recall by days or weeks.
Which products are covered? All lots of GreenWise Organic Whole Blueberries and Whole Mixed Berries in 10-ounce and 48-ounce sizes, with UPCs 41415-06453, 41415-12053, 41415-06753 and 41415-12153.
My lot code was not on the original list. Am I clear? No. The recall was expanded to all lots of these four products, so lot codes no longer determine whether a bag is affected.
Where were they sold? Publix stores in Alabama, Florida, Georgia, Kentucky, North Carolina, South Carolina, Tennessee and Virginia.
How many people have gotten sick? CDC has reported 12 people infected with the outbreak strain in two states, with four hospitalizations and no deaths.
When should someone seek emergency care? Decreased urine output, pale skin, unexplained bruising or bleeding, severe abdominal pain, or confusion after eating the product can indicate hemolytic uremic syndrome and require immediate evaluation.
