Kellanova Customer Service, Product Complaints and Reviews

If you need help with a Kellanova food product, including a quality concern, damaged package, unusual taste or odor, ingredient question, possible foreign material, coupon problem or recall, contact Kellanova Consumer Affairs and keep the product packaging until the issue has been reviewed.

Kellanova’s U.S. brands include products sold under names such as Pringles, Cheez-It, Pop-Tarts, Eggo, MorningStar Farms, RXBAR, Rice Krispies Treats and Nutri-Grain. Mars completed its acquisition of Kellanova in December 2025, so these brands are now part of the larger Mars Snacking business.

How to Report a Kellanova Product Complaint

Consumer Affairs can investigate complaints involving products that appear stale, damaged, incorrectly packaged, unusually flavored, discolored or otherwise different from what a customer expected.

Before calling or submitting the contact form, collect:

• Exact product and flavor
• Package size
• UPC or barcode
• Best-if-used-by date
• Production or manufacturing code
• Store name and location
• Purchase date
• Receipt, if available
• Photographs of the product and package
• A clear description of the problem

Product codes can help Consumer Affairs identify when and where an item was manufactured. Photograph all printed codes before returning or discarding the package.

Kellanova Foreign Object or Contamination Complaints

If you find plastic, metal, glass, mold, an insect or another unexpected object in a food product, stop consuming it and secure the remaining product and package away from children, pets and other food.

Take photographs showing the product, object, packaging and manufacturing information. Contact Kellanova before mailing anything so Consumer Affairs can provide handling instructions.

If someone experiences a serious injury, illness or allergic reaction, seek appropriate medical care. A serious food-safety concern can also be reported to the U.S. Food and Drug Administration in addition to contacting the manufacturer.

Kellanova Product Recalls

Product recalls generally apply only to specific varieties, UPCs, package sizes, manufacturing codes or best-if-used-by dates. Do not assume that every product under a brand is recalled simply because one variety is affected.

For example, MorningStar Farms announced a voluntary recall in June 2026 involving certain Buffalo Chik’n Nuggets and Hot & Spicy Sausage Patties because of possible plastic pieces. The recall notice instructed customers with affected products to discard them and contact Consumer Affairs for a refund.

For any current recall, compare the product in your possession with the exact information in the official notice. The FDA recall database is another useful source for current U.S. food recall information.

Kellanova Refunds, Coupons and Replacements

A product complaint does not automatically guarantee a refund or replacement. Consumer Affairs may request package codes, photographs, purchase information or other details before deciding what resolution is appropriate.

Depending on the circumstances, a response could include a replacement coupon, reimbursement, product information or additional investigation.

For a recently purchased product, the retailer may also have its own return or refund policy. A store refund does not prevent a customer from separately reporting a manufacturing or food-quality concern to Kellanova.

Kellanova Ingredient, Nutrition and Allergen Questions

Recipes and ingredients can change, and similar products may use different ingredients depending on flavor, package size or market. Read the ingredient list and allergen statement on the package currently in your possession rather than relying only on an older website, photograph or third-party product listing.

Contact Consumer Affairs when:

• An ingredient statement is unclear
• The package appears incorrectly labeled
• You need additional allergen or manufacturing information
• The food appears different from the variety shown on the package
• Online information conflicts with the package in your possession

Do not consume a product when you have an unresolved concern involving a serious food allergy.

Kellanova Brands

Kellanova’s current U.S. consumer portfolio includes major snack and frozen-food brands such as:

• Pringles
• Cheez-It
• Pop-Tarts
• Eggo
• MorningStar Farms
• RXBAR
• Rice Krispies Treats
• Nutri-Grain
• Special K snack products

Some brands maintain their own product-specific websites and contact forms. When a telephone number or support address is printed directly on the package, use that information for the product in your possession because consumer-support routing can vary by brand.

Kellanova vs. WK Kellogg

Kellogg Company separated into two companies in October 2023. The snacks-led business became Kellanova, while the North American cereal business became WK Kellogg Co.

This distinction is important for U.S. customer service. Many breakfast cereals carrying the Kellogg’s name are not supported by Kellanova Consumer Affairs.

Products generally associated with the separate North American cereal business include cereals such as:

• Frosted Flakes
• Froot Loops
• Rice Krispies cereal
• Raisin Bran
• Apple Jacks
• Frosted Mini-Wheats
• Corn Flakes

By contrast, products including Pop-Tarts, Cheez-It, Pringles, Eggo, Rice Krispies Treats and MorningStar Farms remained with Kellanova and are now part of Mars Snacking.

If you are unsure, check the manufacturer’s name and customer-service information printed on the package before calling.

Who Owns Kellanova?

Mars, Incorporated completed its acquisition of Kellanova on December 11, 2025. Kellanova’s portfolio joined Mars Snacking alongside brands such as M&M’S, Snickers, Twix, Skittles, Extra and KIND.

The acquisition means Kellanova is no longer the independent publicly traded company it was following the 2023 Kellogg separation. Mars Snacking continues to operate major functions in Chicago.

Consumers do not generally need to contact Mars corporate headquarters about an ordinary Kellanova product complaint. Use the Kellanova or brand-specific Consumer Affairs channel first.
