At the universities, nutritionists and home economists taught a new scientific approach to food. In the early 1900s muckraking journalists raised public concern about the wholesomeness of industrialized food products that contained various preservatives and adulterants of unknown safety.[citation needed] From 1902 to 1912 Harvey Washington Wiley, a chemist at the U.S. Department of Agriculture, supervised "hygienic table trials" to test the safety of food additives and preservatives. His work contributed to the enactment of the Pure Food and Drug Act of 1906. He became the first commissioner of the FDA and later led the laboratories of Good Housekeeping Magazine.[1]
