One of the major accomplishment during Theodore Roosevelt's Presidency concerning American domestic issues was enacting and enforcing the Pure Food and Drug and Meat Inspection act. For the first time in history, the federal government took serious actions to regulate the food industry and assure protection to consumers. From this point on, the government's role regarding the food industry became was more active.
The Pure Food and Drug Act of 1906 was the first law to protect consumers by establishing a series of measures, such as banning foreign and interstate traffic in adulterated or mislabeled food and drug products. It also created the actual Food and Drug Administration.
Meat Inspection Act of 1906, was legislation that established rigorous inspection standards toward the slaughter and procession of livestock. It prohibited the sale of adulterated or misbranded livestock and derived products as food.
Though there had been enacted others Meat Inspection Acts, (1890 and 1891), they weren't as effective as the new Act of 1906 intended to be.
