The U.S. Food and Drug Administration (FDA) has elevated the risk classification for a nationwide butter recall, now labeling it a Class II recall — the second-highest warning level —due to a potential undeclared allergen.

Missouri-based food company Bunge North America has recalled 64,800 pounds - the equivalent of 1,800 cases - of its NH European Style Butter Blend due to undeclared milk allergens. According to a public health notice from the FDA, Bunge distributed the butter to 12 centers located across the United States and one in the Dominican Republic.

Food inspectors are urgently advising consumers not to eat the product recalled over fears about lead and cadmium levels.
