In the turn of the 20th century people all over America were getting sick over the food that they ate and dying because of it
Around 1906 there was a man by the name of Upton Sinclair who was trying to change human conditions in the stock yards by writing a book but what ended up happening is people being shocked by the food conditions in the meat packing industry. One person who was shocked was President Theodore Roosevelt who invited Sinclair to the white house saying “the specific evils you point out shall, if their existence be proved, and if I have the power, be eradicated.”
A big problem that everyone had in the city was that when you bought food you never really knew what was in your food because there was no laws that made the producers actually tell you what was in them. This lead to businesses lying to make more money and make cuts that would save them money.
Another big problem that went hand and hand with false labeling is just the overall sanitation of the food. The meat industry would make meat out of waist and moldy leftovers adding to the health problem people had making people believe that they were buying good meat but in all actuality you could be buying months old meat.
What Sinclair and Roosevelt came up with to fight against false labeling was the Pure Food and Drugs act. This made it illegal to lie about what the companies put into medicine and their food products making it difficult for these companies to trick their customers.
For unsafe food the Pure Food and Drug act didn't outright ban putting rotten meat or harmful chemicals in their food but it gave customers the information they needed to make the right choice in buying food so in the long run the Pure Food and Drug Act stopped companies from making harmful products. Who knows maybe if Roosevelt never passed the act we would still be eating garbage and toxic junk companies let us buy.
