After the passage of the Pure Food and Drug Act, labels such as this on a can of peas
were common. What purpose do labels such as this one serve?
They were required to ensure that price gouging was not taking place on
consumer products.
They served to curtain mass production of products from only certain
manufacturers.
They were provided to ensure that the same preservatives were used in all
processed food.
They serve as a seal of purity and guarantee that the product meets federal
requirements.
