No Formal Recall on Kirkland Walnuts
As of October 2025, there is no active, formal recall on Kirkland Signature walnuts from Costco. Costco maintains an updated list of product recalls on its website, and Kirkland walnuts have not appeared on these lists recently. This is crucial for consumers to know, as widespread concern about nut safety has led to many questions.
While there is no official recall, it is important to distinguish this from customer experience issues. A viral Reddit thread from April 2025 featured numerous reports from consumers about Kirkland walnuts being consistently rancid. While not a health and safety risk requiring a recall by regulatory bodies like the FDA, rancidity significantly impacts product quality and taste. This type of quality issue should be directed to Costco's customer service, as rancid oils can be detrimental to health over time.
Notable Recent Walnut and Nut Recalls (Not Kirkland)
It is important not to confuse recent recalls of other nut products with the status of Kirkland walnuts. Several other brands have issued recalls for different reasons in 2024 and 2025. These examples illustrate the types of issues that can trigger official recall actions.
- Gibson Farms Organic Walnuts (May 2024): A major recall was initiated for organic walnut halves and pieces due to an E. coli O157:H7 outbreak that sickened 12 people. These walnuts were sold in bulk bins at Whole Foods and other grocery stores across 19 states. The walnuts could have been repackaged by stores, so it is vital for consumers to check the original supplier if they purchased bulk organic walnuts during that period.
- Emerald Kettle Glazed Walnuts (August 2024): Flagstone Foods recalled certain packages of Emerald Kettle Glazed Walnuts for undeclared peanut, almond, and pecan allergens. This was a Class II recall, indicating a health risk, especially for those with severe nut allergies.
- Brazil Nuts.com (August 2024): Now Foods recalled Brazil nuts due to high levels of mold and yeast. Molds can produce harmful mycotoxins and cause respiratory issues, making this a Class II recall.
How to Check for the Latest Costco Recalls
Consumers can proactively check for recalls on any product, including Kirkland items, by visiting official sources. Relying on reliable information from Costco and government agencies is the best way to stay safe.
- Costco's Official Website: The dedicated recall page on Costco's website is the most reliable source for updates on products sold at their warehouses. This page is regularly updated and provides specifics on affected item numbers, purchase dates, and what steps to take.

Recognizing and Handling Rancid Walnuts
While not a recall issue, discerning fresh walnuts from rancid ones is a valuable skill for Costco shoppers given previous complaints. Signs of rancidity in walnuts are typically easy to spot through sensory inspection.
- Visual Inspection: Fresh walnuts should have a light, buttery color. If they appear dark, shriveled, or oily, they may be rancid.
- Smell: A fresh walnut has a mild, nutty aroma. Rancid walnuts often have a strong, bitter, or pungent smell, similar to old paint or chemicals.
- Taste: A bitter, soapy, or metallic flavor is a clear indicator that the nut has gone bad. The fresh nut's pleasant, mild taste will be absent.
If you find your Kirkland walnuts are consistently rancid, documenting the issue and providing feedback to Costco directly is the best course of action. This helps them monitor and maintain quality control with their suppliers. You can also visit the official Costco recalls page for any updates on product quality.
Conclusion
In summary, there is no official recall on Kirkland walnuts as of late 2025. The most prominent walnut recall of 2024, involving an E. coli outbreak, was linked to a different supplier, Gibson Farms, and not to the Kirkland brand. However, consumers have reported quality control concerns regarding rancidity in Kirkland walnuts. Shoppers are encouraged to check Costco's official recall page for the latest updates and to report any quality issues directly to customer service. Being aware of the signs of bad nuts and understanding how recalls work is the best way to protect yourself and ensure food safety.
