Ohio Rev. Code § 911.18
Bread shall not be sold or offered or exposed for sale otherwise than by weight and shall be manufactured for sale and sold only in units of not less than twelve ounces. Loaves of bread weighing more than twelve ounces may only be manufactured for sale and sold in increments of two ounces, beginning with the twelve-ounce minimum weight. When multiple loaves are baked, each unit of the loaf shall conform to the weight required by this section. The weight specified means the net weight twelve hours after baking and is to be determined by the average weight of at least twenty-five loaves. Such unit weights do not apply to rolls and such bread as is defined as fancy bread by the director of agriculture. Every loaf of bread manufactured for sale, sold, or offered or exposed for sale shall have affixed thereon a visible and legible statement in plain position of the weight of the loaf of bread, and the business name and address of the manufacturer, packer, or distributor. In the case of wrapped bread, such information shall be stated on the wrapper of each loaf, and in the case of unwrapped bread such information shall be stated by means of a pan impression or other means or shall be stated on a label using plain legible type. Such label affixed to an unwrapped loaf shall not be affixed in any manner which is unsanitary and unwholesome. There shall not be more than one label on a loaf or a unit.
