Between warm and creamy peanut butter toast and almond milk smoothie bowls, breakfast and nuts typically go hand in hand. But not today: Whole Foods announced anyone with a peanut allergy should toss out (or return) one of its beloved cereal items.

According to a press release, the grocery chain is recalling its 365 Everyday Value Organic Raisin Bran because certain boxes could contain peanuts that aren’t listed on the nutrition label. Evidently there was a mix-up on the assembly line, and the boxes got filled with Peanut Butter Cocoa Balls instead of Organic Raisin Bran.

The grocery chain is recalling its 365 Everyday Value Organic Raisin Bran because certain boxes could contain peanuts that aren’t listed on the nutrition label.

To ensure you didn’t buy an affected product, check to see if your box has the UPC code “9948243903” and the best-by date June 4, 2018. The cereal was sold both in Whole Foods Market and online, and anyone with a valid receipt can bring it into the store for a full refund.

Luckily there haven’t been any reported negative reactions to the peanuts, but the allergy can be serious. If you think you’re having a reaction—whether that’s hives and shortness of breath or life-threatening anaphylaxis, which involves the swelling of the throat, dizziness, and loss of consciousness—seek medical attention immediately.
