Labeling lab-grown meat

• In 1869, margarine was invented as a butter replacement. The dairy farmers raised the alarm in the United States; They convinced the U.S. Government to tax margarine and lobbied against the use of yellow dyes to make the butter replacement look more buttery.
• Dairy farmers objected to soymilk and almond milk being called milk, but the FDA hasn't done anything to stop brands from using the word.

Unlike margarine or soymilk, cultured meat is biochemically identical to the substance it's competing with.
