The Food and Drug Administration on August 20 upgraded a recall of frozen blueberries and mixed berries to its highest‑risk Class I designation. Publix grocery stores had initially recalled GreenWise Organic Whole Blueberries and Whole Mixed Berries in early July because of potential E. coli contamination. The agency determined a reasonable probability that the product could cause serious health consequences or death. The affected items were distributed to Publix locations in Alabama, Florida, Georgia, Kentucky, North Carolina, South Carolina, Tennessee and Virginia. Consumers who purchased the berries with an expiration date before February 9, 2028, are advised to discard them or return them to Publix for a refund. The FDA continues to monitor the situation and has not reported any illnesses linked to the product.
