(a) Meat and meat food products are an important source of the supply of human food in this state, and legislation to assure that the food supplies are wholesome, unadulterated, and otherwise fit for human consumption and properly labeled is in the public interest.
(b) Therefore, it is declared to be the policy of this state to provide for the inspection of livestock slaughtered, and the carcasses, parts thereof, and meat food products processed therefrom, for human food, at certain establishments to prevent the distribution in intrastate commerce, for human consumption, of livestock carcasses and parts thereof and meat food products which are unwholesome, adulterated, or otherwise unfit for human food, or are improperly labeled or falsely advertised.
