Have a frozen box of White Castle Original Sliders in your freezer? Pause before you heat it.
What happened
White Castle Frozen Food Division is recalling 1,021 cases of its retail frozen 4‑count cartons labeled as Original Sliders because some boxes actually contain Jalapeño Cheese Sliders — a different product that lists milk and soy. Those allergens are not printed on the Original Slider carton, so anyone with a milk or soy allergy who eats the mislabeled product could face a serious or even life‑threatening reaction.The company says the mix‑up occurred during packaging. The affected cartons were shipped to retailers between August and October 2025 and were sold primarily in convenience stores, with a potential that some reached all 50 states. The recalled boxes are the 4‑count White Castle Original Sliders in a blue-and-white cardboard carton with UPC 0-82988-02969-3. The specific lot codes covered by the recall are 9H203521 and 9H203522; only cartons that show those full eight-character lot codes are included. The cartons carry a Best By date of April 18, 2026 (270‑day frozen shelf life).
The issue came to light after a consumer reported a non‑life‑threatening allergic reaction after eating a slider that turned out to be a Jalapeño Cheese Slider packaged in an Original Slider box. No other reports of injury or illness have been received, according to the company and the U.S. Food & Drug Administration.

How to check and what to do
- Look for the 4‑count retail carton with UPC 0-82988-02969-3 and Best By April 18, 2026.
- Check the lot code printed inside the light‑blue bar on the end panel. Only lot codes 9H203521 and 9H203522 are part of this recall. If the code does not match all eight characters exactly, it is not included.
If you have an affected box and you or someone in your household is allergic or sensitive to milk or soy, do not eat the product. Return it to the place of purchase for a full refund. If you have health concerns after consuming the product, seek medical attention.

Why this matters
Most food recalls for contamination or bacterial risk are about safety in a clinical sense; this one is about undeclared allergens — a hidden hazard for people with immune‑mediated allergies. Allergic reactions can escalate rapidly; accurate labeling is the basic defense consumers rely on when shopping, especially for packaged and frozen foods.White Castle stresses that this recall applies only to the specific retail 4‑count frozen cartons described above. Restaurant sliders and other White Castle grocery items are not affected.
If you want the official word and photos to help identify the carton, consult the FDA recall notice linked above. The agency’s page includes images of the package and the exact lot codes so you can match what’s in your freezer.
