Ohio Rev. Code § 911.05: Ingredients.

No ingredient which is likely to deceive the consumer or which lessens the nutritive value shall be used in any bakery product unless such product is plainly labeled, branded, or tagged, or unless there is a sign making plain to the purchaser or consumer the actual ingredients. In the case of unwrapped bread to be sold by the loaf, such labeling, branding, or tagging shall be placed upon the label provided for by section 911.18 of the Revised Code, which shows the name of the manufacturer and the net weight of the loaf.
