Choose a sealed, undamaged bag of berries that appears solidly frozen, then check the product identity, ingredients, storage directions, date wording, and lot or product code. At home, keep the freezer at 0°F (-18°C). Those checks help with quality, handling, and recall identification, but neither a package nor a date can prove that berries are free of pathogens.
How do I choose frozen berries?
Compare bags by what is in them, how they were handled, and whether their identifying details are readable—not by assuming a brand, country of origin, or organic label is inherently safer. FDA guidance does not rank berry brands or establish that organic, imported, domestic, or a particular package type is safer.

- Berry type and intended use: Choose a single fruit or blend that suits the recipe. Berries added to smoothies, yogurt, or fruit salad may be eaten without a cooking step; baking generally includes one.
- Ingredients: Check whether the bag contains only fruit or includes added sugar or other ingredients. The reviewed official guidance establishes no safety or nutritional advantage for a particular sweetening choice.
- Package and frozen condition: Prefer a sealed, intact package with berries that appear solidly frozen. Avoid tears, leaks, or signs of thawing and refreezing.
- Traceability: Make sure the product identity and any lot or product code are legible, so you can compare them with a recall notice if needed.
- Grade, if listed: USDA frozen-berry grades describe quality characteristics such as color, defects, character, flavor, and odor. A grade is not a safety certification.
Loose berries can be easier to portion, but clumping by itself is not a reliable safety test. The reviewed guidance does not define a visual clump test; package condition and temperature history matter more.

Read the product name and berry type, ingredient list, storage and preparation directions, date wording, and any lot, UPC, or other product identifier. FDA explains that a use-by date generally reflects the manufacturer’s recommendation for best quality, not a universal food-safety deadline; infant formula is an exception. Follow the specific package directions.

A printed date cannot establish whether a bag was kept frozen continuously or whether its particular lot has been recalled. Recall notices may identify products by name, package size and type, UPC, lot code, sell-by or use-by date, package image, and distribution area. Compare the exact details and follow the notice’s instructions. See FDA’s guide to food recalls and its food storage guidance.
As a specific example, an FDA-distributed notice dated July 29, 2026 said Publix recalled all lots of GreenWise Organic Whole Blueberries and Whole Mixed Berries because of possible E. coli O145:H28 contamination. The notice described distribution to Publix stores in Alabama, Florida, Georgia, Kentucky, North Carolina, South Carolina, Tennessee, and Virginia, and warned of potentially serious complications, particularly for young children, older adults, and people with weakened immune systems. This was a product-specific recall, not evidence that all frozen berries or all organic berries are unsafe. Check the live FDA recall information for current notices; affected products and lots can change.

How can I judge packaging and frozen condition?
Do not buy an open, torn, leaking, or suspiciously resealed bag, or one that appears to have thawed and refrozen. FDA notes that stains or leakage on frozen-food cartons can indicate that contents thawed. These are useful handling checks, not pathogen tests. FDA’s consumer advice on frozen foods describes signs of possible thawing and refreezing.

Do not rely on smell or appearance alone after a temperature incident at home. If a freezer’s temperature is unknown, FDA says food with ice crystals remaining or at 40°F or below can be refrozen or cooked. USDA FSIS gives the same rule for partially thawed food and notes that quality may decline. This home guidance is not a reason to choose a visibly thawed-and-refrozen bag at the store.

Are frozen berries safe to eat raw?
Most frozen berries are eaten safely, but freezing does not sterilize them. FDA says freezing stops bacterial growth but does not kill most bacteria; it also explains that viruses can survive low temperatures and generally are not killed by freezing. That matters when berries go straight into smoothies, yogurt, or fruit salad without a cooking step.
FDA’s FY 2019–2023 microbiological sampling assignment found hepatitis A virus and norovirus contamination rates below 1% among sampled frozen strawberries, raspberries, and blackberries. The agency found no statistical difference in HAV or norovirus prevalence by domestic versus imported origin for each berry type, and reported no evidence linking violative products in that assignment to foodborne illness outbreaks. These findings apply to those samples and that assignment, not every bag, future lot, or virus. FDA also reported that the 2023 frozen organic strawberry hepatitis A outbreak resulted in 10 illnesses and four hospitalizations. Its 2020 update described three U.S. hepatitis A outbreaks and one norovirus outbreak linked to frozen berries from 1997 through 2016; those historical counts are not a current prevalence estimate. See the FDA FY 2019–2023 frozen-berry sampling report and FDA’s update on sampling frozen berries for harmful viruses.

How should I store frozen berries?
Set the freezer to 0°F (-18°C) and follow the package’s storage directions. FDA says properly handled food kept at that temperature remains safe indefinitely, while quality can decline over time. Flavor, texture, aroma, juiciness, and color may change. Freezer burn is a quality problem, not by itself a food-safety problem. See FDA’s storage guidance.
If the power goes out
- Keep the freezer door closed. FDA says a full freezer can maintain an adequate temperature for about 48 hours if it remains unopened.
- If the freezer’s temperature is unknown, check whether the berries still have ice crystals or are at 40°F or below. FDA says food meeting either condition can be refrozen or cooked.
- Do not use smell or appearance alone to decide whether food is safe after a temperature incident.
If berries partially thaw
USDA FSIS says partially thawed food can be refrozen if ice crystals remain or its temperature is 40°F or below, though quality can suffer. Follow the package’s handling directions as well.
