Frozen blueberries are a staple in many households—convenient, nutritious, and versatile. Whether blended into smoothies, baked into muffins, or sprinkled over oatmeal, their year-round availability makes them a go-to source of antioxidants and fiber. But in recent years, concerns have arisen about potential recalls, particularly related to foodborne illnesses. So, is there a recall on frozen blueberries? The answer isn’t a simple yes or no—and that’s why it’s critical to stay informed. This comprehensive guide will explore recent recalls, health risks, how to check product safety, and what you can do to protect yourself and your family.
Recent Frozen Blueberry Recalls: A Closer Look
Food safety agencies around the world monitor perishable and frozen products closely. While frozen blueberries are typically safe due to the freezing process inhibiting bacterial growth, contamination can still occur at any stage—harvesting, processing, packaging, or distribution.
Between 2017 and 2024, several major recalls involving frozen blueberries have taken place. The most notable incidents were linked to potential contamination with hepatitis A virus and norovirus, both of which can cause serious gastrointestinal illness.
2023 Recall: Naturkolo Brand Frozen Blueberries
In October 2023, the U.S. Food and Drug Administration (FDA) announced a recall of Naturkolo brand frozen blueberries imported from Mexico. The trigger? Routine testing identified the potential presence of hepatitis A virus. The affected products were distributed across multiple states, including California, Texas, Illinois, and Florida.
The recall covered two package sizes:
- 16-ounce bags labeled “Naturkolo Organic Blueberries” with UPC 075279704178
- 32-ounce bags with UPC 075279704185
Distribution dates spanned from June to September 2023. Consumers who had purchased these products were urged to discard them immediately or return them to the place of purchase for a full refund.
2020 Hepatitis A Outbreak Linked to Frozen Blueberries
One of the most concerning incidents occurred in early 2020 when frozen blueberries imported from the United States were identified as the likely source of a hepatitis A outbreak in New Zealand and Australia. The outbreak led to dozens of confirmed illnesses and prompted emergency actions from public health authorities.
New Zealand’s Ministry for Primary Industries (MPI) issued a recall for certain batches of Woodstock Organic Frozen Blueberries sold at major retailers. Similarly, Australia’s Food Standards agency pulled products from shelves under the Silver Spoon and Woolworths brands, all of which used imported U.S. berries.
Symptoms in affected individuals ranged from mild nausea and fatigue to jaundice and liver inflammation, underscoring the severity of viral contamination.
The 2016 Norovirus Incident: A Wake-Up Call
Earlier, in 2016, a large recall involving frozen berries—primarily blueberries and raspberries—was initiated due to norovirus contamination. The U.S. Centers for Disease Control and Prevention (CDC) traced the virus to frozen berries imported from Egypt. Though the recall included multiple berry types, frozen blueberries were part of the impacted inventory.
The incident prompted a reevaluation of food safety protocols for imported frozen produce. It also demonstrated that freezing does not always eliminate viruses, especially those that are highly resistant to cold.
Why Are Frozen Blueberries at Risk of Contamination?
Despite their long shelf life, frozen blueberries are not immune to health hazards. Understanding why contamination occurs helps explain the need for vigilance.
Contamination During Harvesting and Picking
Blueberries are often picked by hand in large fields. If farm workers are infected with viruses like hepatitis A or norovirus and fail to follow proper hygiene protocols—such as handwashing—contamination can transfer directly to the fruit. This is particularly concerning in regions with limited access to sanitation facilities.
Cross-Contamination in Processing Facilities
Once harvested, berries are transported to processing plants where they may be washed, sorted, and frozen. If equipment or water used in washing is contaminated—even with traces of fecal matter—viruses can spread rapidly across large batches. Cross-contamination from other contaminated products on shared lines also poses a significant risk.
Frozen Produce: Misconceptions About Safety
Many consumers believe that freezing kills harmful pathogens, but this is a common misconception. While freezing can inhibit bacterial growth, it does not destroy viruses. Hepatitis A and norovirus can remain viable in frozen berries for months, sometimes even up to a year. The only reliable way to kill these viruses is through thorough cooking.
Why Freezing Doesn’t Kill Hepatitis A
Hepatitis A virus is incredibly resilient. It can withstand freezing, drying, and even mild heat. The CDC recommends heating food to at least 185°F (85°C) for one minute to inactivate the virus. For this reason, simply thawing or lightly incorporating frozen berries into uncooked dishes may not be enough to ensure safety, especially for vulnerable populations.
How to Check If Your Frozen Blueberries Are Recalled
You can’t rely on appearance or smell to detect contaminated frozen blueberries. Instead, it’s essential to stay informed through official channels.
Monitor Official Recall Alerts
Government agencies post recall notices online in a timely manner. Key sources include:
- The U.S. FDA’s website: fda.gov
- The USDA Food Safety and Inspection Service (FSIS)
- Health Canada’s Recalls and Safety Alerts page
- Australia’s Food Standards website
- The European Food Safety Authority (EFSA)
These organizations update their databases daily and often provide searchable recall lists by product name, brand, UPC, or batch number.
Check Packaging Details
If you’re concerned about a specific package, examine the following:
| Information to Check | Where to Find It |
|---|---|
| Brand name | Front of packaging |
| UPC number | Barcode on the back |
| “Best By” or expiration date | Sometimes on the side or back |
| Country of origin | May be listed near barcode or ingredients |
| Batch or lot number | Printed near expiration date |
Cross-reference these details with active recall lists. Many retailers also publish recall notices on their websites, especially if they sold the affected products.
Use the FDA’s Recalls, Market Withdrawals, & Safety Alerts Page
The FDA offers a powerful search tool at www.fda.gov/safety/recalls. You can filter by product type, reason for recall, and date. For frozen blueberries, search terms like “blueberry,” “hepatitis A,” or “frozen berries” can quickly yield relevant results.
Sign Up for Recall Notifications
To stay ahead of potential risks, consider signing up for email or text alerts:
– FDA ‘Recall’ email subscriptions
– USDA’s Food Recall Notifications
– Retailer-specific safety alerts (e.g., Costco, Walmart, or Whole Foods)
These services deliver immediate alerts when a product you care about is flagged.
Balancing the Benefits and Risks of Frozen Blueberries
Despite occasional recalls, frozen blueberries remain a healthy and convenient food choice. The benefits often outweigh the risks—especially when proper precautions are taken.
Nutritional Value of Frozen Blueberries
Frozen blueberries retain much of the nutritional profile of fresh ones. Studies have shown that freezing can actually preserve antioxidants like anthocyanins, which give blueberries their rich color and anti-inflammatory properties.
A 1-cup serving of frozen blueberries typically provides:
– 80 calories
– 1.1 grams of protein
– 20 grams of carbohydrates
– 3.6 grams of dietary fiber
– 14 milligrams of vitamin C
– 0.5 milligrams of manganese
– High levels of polyphenols and flavonoids
These nutrients contribute to cardiovascular health, cognitive function, and may even help regulate blood sugar levels.
Economic and Environmental Advantages
Frozen blueberries are often more affordable than fresh, especially outside harvest season. They also reduce food waste since they can be stored for up to 12–18 months without spoiling. This makes them an excellent choice for budget-conscious and environmentally aware consumers.
The Role of Organic vs. Conventional Labels
Many consumers believe organic frozen blueberries are inherently safer, but this isn’t always true. While organic farming restricts the use of synthetic pesticides, it doesn’t guarantee immunity from viral contamination. In fact, several past recalls—including the 2023 Naturkolo incident—involved certified organic products.
That said, organic producers may follow stricter worker hygiene and environmental standards. Still, the “organic” label does not make a product recall-proof.
Who Is Most at Risk from Contaminated Frozen Blueberries?
While healthy adults may recover from viral foodborne illnesses, some populations face higher risks of complications.
High-Risk Groups Include:
– Young children under 5 years old
– Adults over 60
– Pregnant women
– Individuals with compromised immune systems (e.g., cancer patients, organ transplant recipients)
– People with chronic liver disease
For these individuals, hepatitis A can lead to prolonged illness, liver damage, and even hospitalization. Therefore, caution is especially important when serving frozen berries to high-risk populations.
Prevention Tips for Vulnerable Consumers
To reduce risk:
– Avoid consuming raw or uncooked frozen blueberries if you’re in a high-risk group.
– Always cook berries to 185°F (85°C) before consumption.
– Wash hands thoroughly after handling frozen berries.
– Opt for brands with transparent sourcing and strong food safety records.
What Should You Do If You Have Recalled Blueberries?
If you discover that you own a recalled batch of frozen blueberries, follow these steps immediately:
1. Stop Consumption
Do not eat, serve, or use the berries in any recipe—even if they’ve been thawed or look “fine.”
2. Isolate the Product
Place the product in a sealed plastic bag to prevent accidental use and clearly label it as “Recalled – Do Not Consume.”
3. Discard or Return
Dispose of the product safely in a covered trash can inaccessible to pets or children. Alternatively, return it to the store for a refund. Keep your receipt if the store requires it.
4. Monitor for Symptoms
If you’ve consumed the recalled berries within the past 15–50 days (the incubation period for hepatitis A), watch for symptoms such as:
– Fatigue
– Nausea or vomiting
– Abdominal pain
– Loss of appetite
– Dark urine
– Jaundice (yellowing of skin or eyes)
Seek medical attention if symptoms develop, and inform your healthcare provider about your potential exposure.
5. Report the Incident
You can report suspected illness from contaminated food to the FDA’s MedWatch program or your local health department. Your report helps track outbreaks and improve food safety oversight.
How Producers Are Improving Safety Standards
In response to recurring recalls, the frozen berry industry has implemented stricter protocols. These include:
Enhanced Supplier Audits
Major distributors now require farm certifications and conduct on-site audits in exporting countries. This helps verify worker hygiene, water quality, and harvesting practices.
Improved Sanitation in Processing Plants
Modern facilities use ozonated water, UV treatment, and advanced filtration to reduce microbial load before freezing. Some companies also conduct third-party testing for viral contaminants.
Traceability Systems
Blockchain and digital tracking technologies allow companies to pinpoint the exact source of contamination—down to a single farm or harvest batch. This means faster recalls and better consumer protection.
Consumer Education Campaigns
Brands like Cascadian Farm and Wyman’s have started educating consumers through packaging labels. These include warnings like “Wash before eating” and “Cook to destroy potential pathogens,” especially on products likely to be used raw.

Why are frozen blueberries being recalled in 2024?
In 2024, certain brands of frozen blueberries are being recalled due to potential contamination with harmful pathogens, particularly hepatitis A and norovirus. These recalls are initiated after routine testing by health authorities or internal quality checks by manufacturers reveal the presence of these viruses in samples. Contamination typically occurs due to poor hygiene practices during harvesting, handling, or processing, either through contaminated water or improper worker sanitation.
Public health officials emphasize that while frozen fruits are generally safe, outbreaks linked to imported frozen berries have occurred in previous years, prompting stricter monitoring. The recalls in 2024 are precautionary in many cases, aiming to prevent illness even if no confirmed cases are reported. Consumers are urged to stay informed by checking official updates from food safety agencies such as the FDA or Health Canada for specific details on affected batches.
Which brands of frozen blueberries are affected by the 2024 recall?
As of 2024, several brands across North America and Europe have issued voluntary recalls on specific lots of frozen blueberries. Included among them are major retailers’ private labels and well-known frozen fruit brands such as Nature’s Touch, Kirkland Signature (Costco), and President’s Choice. The affected products typically include unflavored, unsweetened frozen blueberries sold in various sizes, but not all products from these brands are impacted—only those with specific batch codes and best-before dates listed in the recall notices.
Consumers can identify the affected products by checking the packaging for lot numbers, production dates, and country of origin. Most recalls target blueberries imported from specific regions where contamination risks are higher. Regulatory agencies usually publish detailed product lists, distribution areas, and photos of packaging on their websites. If in doubt, the safest action is to contact the manufacturer or retailer directly using the customer service information on the package.
How can consuming recalled frozen blueberries affect my health?
Consuming contaminated frozen blueberries can lead to foodborne illnesses such as hepatitis A or norovirus infection. Hepatitis A affects the liver and may cause symptoms like fatigue, nausea, abdominal pain, jaundice, and dark urine, appearing two to seven weeks after exposure. Norovirus, on the other hand, results in acute gastroenteritis, marked by vomiting, diarrhea, stomach cramps, and fever, usually within 12 to 48 hours of ingestion.
While most healthy individuals recover without long-term issues, these illnesses can be severe for vulnerable populations, including young children, the elderly, and those with compromised immune systems. Hepatitis A can lead to prolonged illness or, in rare cases, liver failure. Since frozen berries are often consumed without cooking—which would kill pathogens—the risk of infection is higher. Anyone experiencing symptoms after consuming frozen blueberries should seek medical attention and consider reporting the case to health authorities.
What should I do if I have a recalled batch of frozen blueberries at home?
If you discover that you have a recalled batch of frozen blueberries, do not consume them under any circumstances. Immediately remove the product from your freezer and prevent others in your household from using it. Check the official recall notice for disposal instructions; most recommend sealing the product in a bag and throwing it in the trash to prevent accidental ingestion by people or animals.
You are typically eligible for a full refund through the retailer or manufacturer. Many companies allow returns without a receipt, especially during health-related recalls. Contact the company via their customer service line, website, or the information listed in the recall notice to initiate the refund process. Additionally, reporting your discovery to local health authorities helps track the effectiveness of the recall and prevents further distribution of contaminated products.
Are organic frozen blueberries safer than conventional ones during recalls?
Organic frozen blueberries are not inherently immune to contamination, and they can be affected by the same recalls as conventional brands. The organic label refers to farming practices—such as the absence of synthetic pesticides and fertilizers—but does not guarantee protection against microbial pathogens like hepatitis A or norovirus. Contamination often occurs post-harvest, during handling and processing, stages not significantly different between organic and conventional supply chains.
In fact, several recent recalls, including those in 2024, have included organic varieties due to the same contamination risks. Both types of blueberries, especially when imported, must go through rigorous safety checks. Consumers should not assume that the organic certification equates to higher safety in terms of microbiological contamination. It’s important to check recall lists regardless of whether the product is labeled organic or conventional.
How can I safely consume frozen blueberries to minimize health risks?
To reduce the risk of illness from frozen blueberries, consider cooking or heating them before consumption, especially if serving to vulnerable individuals. Heating berries to an internal temperature of at least 85°C (185°F) for one minute can effectively kill pathogens like hepatitis A and norovirus. This is especially recommended when using frozen blueberries in smoothies, baked goods, or sauces where heat treatment is feasible.
Alternatively, thoroughly washing is not sufficient to eliminate viruses from frozen berries, as these can adhere to the surface or penetrate the skin. Instead, some health agencies recommend boiling or simmering frozen berries for one minute if consumed raw. Staying updated on recall alerts, purchasing from reputable brands, and checking product origins can also enhance safety. When in doubt, discarding suspect products is the safest course of action.
Where can I find the latest updates on frozen blueberry recalls in 2024?
The most reliable sources for up-to-date recall information on frozen blueberries are official government health and food safety websites. In the United States, the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) regularly post alerts and investigation updates. In Canada, Health Canada and the Canadian Food Inspection Agency (CFIA) provide detailed recall notices, including product images and distribution details.
Additionally, many grocery chains and brand manufacturers issue recall notices through their websites and customer email alerts. Signing up for food recall notifications from these sources can help you stay informed. Social media channels of health departments and consumer protection groups may also provide timely updates. Always verify information through official channels to avoid misinformation or scams related to fake recalls.
