The Meat Inspection Act gives the Secretary of Agriculture the power to order meat inspections and condemn meat found unfit for human consumption. The law also requires 100 percent accuracy on all food labels. Publications such as The Jungle by Upton Sinclair played a role in the passing of the act by calling attention to the poor conditions in American meat-packing plants. The Pure Food and Drug Act, enacted on the same day, gives the government jurisdiction over food in interstate commerce.
