Aldi has recalled more than 500,000 packages of its mac and cheese sold in the United States after regulators identified undeclared allergens in the product, according to reporting that cites FDA action. The recall is expanded across the US and covers the affected packaged items. The FDA has upgraded the recall classification to Class II, which indicates that consuming the product can cause serious health consequences, though the level of risk is generally considered less than Class I. The issue centers on the presence of allergens that are not properly declared on the product label, raising potential safety concerns for people with sensitivities or allergies. Consumers who have purchased the recalled mac and cheese are advised to stop using it and follow the recall guidance provided by the retailer and the FDA. The recall action highlights the importance of accurate allergen labeling for consumer safety. Additional details such as specific product identifiers and distribution information are referenced in connection with the FDA’s recall update and the retailer’s notice.
