🩺 Today’s Health Focus
A current food-safety investigation in the United States is drawing attention to E. coli O145:H28 infections associated with recalled frozen berry products.
According to the latest FDA update, 17 people in two states had been identified with the outbreak strain, six had been hospitalized, and no deaths had been reported. Illnesses began between May 11 and August 2, 2026. The investigation remains ongoing, meaning additional information or recalled products could be identified.
The situation is a reminder that frozen food is not automatically free from harmful bacteria. Some foodborne pathogens can survive freezing, which is why recalled products should never be tasted simply to determine whether they are safe.
What products are involved?
The FDA currently lists recalled products including certain GreenWise organic frozen blueberries and whole mixed berries, as well as a specific lot of Great Value Organic Triple Berry Blend.
The recalled Great Value product is a 10-ounce package with lot code 6040 01-6 and a best-by date of February 9, 2028.
The affected products were distributed through retailers in multiple U.S. states and Puerto Rico. Because recalls can change as investigations continue, consumers should check the latest FDA recall information rather than relying on an older social-media post or news report.
💬 Health Check: What Is E. coli?
Escherichia coli, commonly called E. coli, is a group of bacteria. Many types normally live in the intestines of people and animals without causing illness.
However, some strains can cause food poisoning and intestinal disease.
The outbreak under investigation involves E. coli O145:H28, a strain associated with Shiga toxin-producing E. coli (STEC) infections. STEC can cause severe diarrhea and, in some cases, a serious complication called hemolytic uremic syndrome (HUS).
This distinction matters: not every E. coli infection has the same symptoms or severity.
🚨 E. coli Symptoms to Watch For
Symptoms vary depending on the type of E. coli involved.
Common symptoms of diarrheal E. coli infection include:
Diarrhea, which can be watery or bloody
Severe stomach cramps
Vomiting
Fever
Nausea
Symptoms can begin several days after exposure. The FDA notes that symptoms associated with the current investigation may begin anywhere from a few days after consuming contaminated food to as long as nine days later.
When diarrhea needs medical attention
Seek medical advice if you develop:
Bloody diarrhea
Diarrhea or vomiting lasting more than two days
A high fever
Significant dehydration
Blood in the urine
Very little or no urination
Unusual tiredness
Unexplained bruising or tiny red spots on the skin
These symptoms can indicate a more serious infection or complication.
⚠️ Understanding HUS: A Serious E. coli Complication
One of the most important complications associated with STEC infection is hemolytic uremic syndrome (HUS).
HUS can damage the kidneys and may become life-threatening.
Warning signs include:
Urinating much less frequently or not at all
Blood in the urine
Unexplained bruising
Tiny red spots on the skin
Extreme tiredness
Irritability
Reduced alertness
HUS is a medical emergency. Anyone experiencing these symptoms after a diarrheal illness should receive urgent medical attention.
Young children, particularly those under five, are among the groups at greater risk of HUS after diarrheal E. coli infection.
🧊 Does Freezing Kill E. coli?
Freezing food can slow or stop the growth of many microorganisms, but it does not reliably eliminate all harmful bacteria.
That means a contaminated frozen food can remain a food-safety concern after being stored in a freezer.
This is why consumers should follow recall instructions rather than trying to make recalled food safe by freezing it longer, thawing it, washing it, or cooking it without specific guidance.
🛑 What to Do If You Have Recalled Frozen Berries
If you discover a recalled product in your freezer:
1. Do not eat it
Do not taste the product to determine whether it is contaminated.
2. Check the package information
Compare the product name, package size, lot code and best-by date with the current recall notice.
3. Throw it away or return it
The FDA advises consumers not to eat, sell or serve recalled products. Recalled berries should be discarded or returned to the place of purchase.
4. Clean areas the berries touched
Clean and sanitize containers, utensils, shelves and other surfaces that may have contacted the recalled product.
5. Wash your hands
Wash your hands thoroughly with soap and water after handling recalled food or cleaning potentially contaminated areas.
These steps help reduce the possibility of cross-contamination.
💧 What to Do If You Develop Diarrhea
Staying hydrated is one of the most important steps when diarrhea or vomiting occurs.
Take fluids regularly, especially if you are losing fluid through diarrhea or vomiting. Oral rehydration solutions can be particularly useful when dehydration is a concern.
Watch for:
Very dark urine
Little or no urination
Excessive thirst
Dry mouth
Dizziness or light-headedness
Lack of tears when crying in young children
Dehydration can develop quickly, especially in young children.
Don't automatically take anti-diarrheal medicine
People with suspected STEC infection should not use anti-diarrheal medicines without medical advice.
The CDC specifically advises against using anti-diarrheal medication with STEC infection because it can increase the risk of HUS. Anti-diarrheal medicines should also be avoided when someone has bloody diarrhea or a high fever.
What about antibiotics?
Antibiotics should not be started on your own when STEC infection is suspected.
The CDC advises against antibiotics for STEC infections because they may increase the risk of HUS. A healthcare professional can determine what testing and treatment are appropriate.
👨👩👧 Who Should Be Especially Careful?
Anyone can develop foodborne illness, but complications can be more concerning in certain groups.
Extra attention is warranted when symptoms occur in:
Children under five
Older adults
People with weakened immune systems
People who become significantly dehydrated
Anyone developing bloody diarrhea or signs of HUS
Parents and caregivers should pay particular attention to urination, fluid intake, energy level and changes in behavior when a young child has significant diarrhea or vomiting.
🌿 Healthy Living Spotlight: Safer Frozen-Food Habits
Frozen fruits and vegetables can be nutritious and convenient. You don't need to avoid frozen produce simply because a specific recall has occurred.
Instead, build a few practical food-safety habits into your routine.
Check recalls regularly
If you frequently purchase frozen fruits, vegetables, berries or prepared foods, periodically check your country's food-safety authority for recalls.
Keep packaging until the food is used
Original packaging makes it much easier to identify a lot code, product number or best-by date if a recall is announced.
Keep recalled foods separate
If you learn that a product in your freezer has been recalled, avoid placing other foods on top of it or allowing the package to contact ready-to-eat foods.
Clean your freezer after a recalled-food incident
If a recalled product has leaked or contaminated another surface, clean the affected area thoroughly according to food-safety guidance.
Wash your hands
Handwashing remains one of the simplest ways to reduce the spread of foodborne pathogens.
🥣 Should You Stop Eating Frozen Berries?
No blanket avoidance of frozen berries is necessary because of this investigation.
The important distinction is between recalled products and frozen berries generally.
Frozen fruits can be part of a balanced diet and provide nutrients and fiber. The appropriate response to a recall is to identify and remove the affected product, follow official instructions and continue practicing good food hygiene.
For readers outside the United States, the specific brands and lots in this investigation may not apply to products sold in your country. However, the general food-safety principles are relevant worldwide.
Always follow your own country's food-safety authority for local recalls.
💡 Health Tip of the Week
Make “check before you eat” part of your food-safety routine.
When you hear about a food recall, don't rely only on the product's appearance or smell. Harmful bacteria may not change the way food looks, tastes or smells.
Instead:
Find the official recall notice.
Check the exact product name.
Compare the package size.
Check the lot or batch number.
Check the best-by or use-by date.
Follow the official disposal or return instructions.
This small habit can be especially valuable for foods stored for long periods in freezers or cupboards.
🧠 Did You Know?
The number of confirmed foodborne infections in an outbreak may not represent the total number of people who became sick.
Some people recover without visiting a healthcare professional, while others may not receive testing that identifies the specific bacteria responsible.
CDC notes that recent illnesses may also take several weeks to be linked to an outbreak during an investigation.
That's why outbreak numbers can change as health authorities receive new reports and laboratory information.
🩺 When Should You Contact a Healthcare Professional?
Contact a healthcare professional if you develop symptoms that could indicate a significant E. coli infection, particularly:
Bloody diarrhea
Severe abdominal cramps
Persistent diarrhea or vomiting
High fever
Significant dehydration
Reduced urination
Blood in the urine
Unexplained bruising
Extreme tiredness or reduced alertness
If symptoms are severe or signs of HUS develop, seek urgent medical care.
If you believe you consumed a recalled product and subsequently became ill, tell the healthcare professional about the food exposure. This information can help guide evaluation and reporting.
📌 The Bottom Line
The current frozen-berry E. coli investigation is a useful reminder that food safety doesn't end when food reaches the freezer.
The FDA's latest information identifies recalled GreenWise and Great Value frozen berry products and reports 17 illnesses and six hospitalizations in the outbreak investigation as of the latest update. The investigation remains ongoing.
For consumers, the most important steps are simple:
Check recalls. Don't eat recalled food. Clean surfaces that may have been contaminated. Stay hydrated if diarrhea occurs. And seek medical attention for bloody diarrhea, severe symptoms or signs of HUS.
