In the late 19th Century, a researcher by the name of Dr. Harvey Washington Wiley. He had discovered that food manufacturers were adulterating and misbranding many of their food products. Dr. Wiley had realized that these chemicals being added to these food products were dangerous for human consumption and were not being put on the labels. Dr. Wiley realized this was a huge problem for Americans and dedicated his career to fight for regulations against this. He started an experimental group called the Poison Squad which helped to bring media attention to this issue.
