CPG Sec. 505.300 "Butter-Nut" Bread
Inquiries have been received about the use of the name "Butter-Nut" on the wrapper of white bread. This term has apparently been in general use since as early as World War 1. No action has ever been taken against a product because of this name.
The FDA does not have information that the labeling of bread as "Butter-Nut Bread" is misleading to consumers; therefore, no action will be instituted against a product solely because of the use of this name.
