FDA Upgrades Frozen Blueberry Recall to Class I Due to Listeria Contamination Risk

Oregon Potato Company Recalls 55,689 Pounds of Individually Quick Frozen (IQF) Blueberries Amid Severe Health Warnings

The U.S. Food and Drug Administration (FDA) has officially upgraded a significant food safety action involving the Oregon Potato Company, elevating the status of its frozen blueberry recall to Class I.

This classification is the most serious level of warning issued by federal regulators, indicating that the consumption of the affected product carries a "reasonable probability" of causing serious adverse health consequences or death.

With approximately 55,689 pounds of fruit currently under recall, the focus has shifted toward the institutional supply chain to prevent the spread of Listeria monocytogenes.

Understanding the FDA Class I Recall Upgrade

The initial recall, which began on February 12, 2026, was recently reclassified on Tuesday following a rigorous safety assessment by federal officials. A Class I recall is not a designation the FDA uses lightly; it is reserved for the most dangerous contamination scenarios. In this case, the Oregon Potato Company, operating under the Willamette Valley Fruit Company brand in Salem, Oregon, identified potential Listeria contamination during routine product testing.

While the recall originally covered a substantial volume of Individually Quick Frozen (IQF) blueberries, the elevation to the highest risk level underscores the life-threatening nature of the pathogen involved. For businesses and large-scale food service providers, this means immediate action is required to secure and destroy any remaining inventory.

Affected Product Details and Distribution Channels

The recalled blueberries were not sold directly to consumers in retail grocery stores but were instead distributed in bulk for use in industrial or food service settings. This makes tracking the product particularly critical for bakeries, restaurants, and food processors. The 55,689 pounds of blueberries were shipped to Michigan, Oregon, Washington, Wisconsin, and parts of Canada.

The affected products are packaged in the following formats:

30-pound corrugated cases with polyethylene liners: Lot codes 2055 B2 (Exp. 7/23/2027), 2065 B1, and 2065 B3 (Exp. 7/24/2027).

1,400-pound industrial totes: Lot codes 3305 A1 and 3305 B1 (Exp. 11/25/2027).

Entities holding these lot codes are urged to stop using the product immediately. Because these berries have a shelf life extending into 2027, there is a high risk that contaminated fruit could remain in deep-freeze storage for months if inventory isn't checked thoroughly.

The Deadly Nature of Listeria Monocytogenes

Listeria monocytogenes is a particularly resilient bacterium. Unlike many other foodborne pathogens, it can survive and even grow in refrigerated and freezing temperatures, making frozen fruit a perfect vehicle for its persistence. If consumed, it leads to Listeriosis, a serious infection that presents a major threat to specific high-risk populations.

Symptoms of infection can include high fever, severe headache, neck stiffness, nausea, and abdominal pain. However, for pregnant women, the risk is catastrophic, as the infection can lead to miscarriages, stillbirths, or premature delivery. Furthermore, the elderly (65+) and individuals with compromised immune systems face a significantly higher mortality rate from systemic Listeria infections compared to the general population.

Food Safety Protocols and Compliance

The Oregon Potato Company has been working in cooperation with the FDA to notify all consignees by email. The process involves a total audit of the supply chain to ensure that the contaminated blueberry batches are either returned or destroyed under supervised conditions.

For commercial kitchens and industrial food manufacturers, this event serves as a stark reminder of the importance of Good Agricultural Practices (GAP) and the necessity of rigorous microbiological testing at every stage of the cold chain.

Industry experts note that frozen fruit recalls due to Listeria have become more frequent as testing technology becomes more sensitive. However, the scale of this specific recall—nearly 60,000 pounds—highlights a significant vulnerability in bulk distribution.

The upgrade to a Class I recall by the FDA for the Oregon Potato Company’s blueberries is a sobering reminder that the "frozen" status of a product does not equate to "sterile."

The food industry often treats the freezer as a safety net, but Listeria laughs at the cold. What makes this situation particularly concerning is the bulk distribution model. Because these were sold in 1,400-pound totes and 30-pound cases, the end-user might not even be aware of the original lot code by the time the berries are baked into a muffin or blended into a smoothie.

From a safety perspective, we are seeing a trend where regulatory transparency is catching up to supply chain complexities. The fact that no illnesses have been reported yet is a testament to the speed of the current reporting system, but the 2027 expiration date means the danger remains "frozen in time" for anyone who misses the memo. It is imperative that food service operators treat lot code tracking with the same level of urgency as their financial accounting; in cases like this, it is literally a matter of life and death.
