Industrial Bio-Test Laboratories
Industrial Bio-Test Laboratories was an American industrial product safety testing laboratory. IBT conducted significant quantities of research for pharmaceutical companies, chemical manufacturers and other industrial clients; at its height during the 1950s, 1960s, and 1970s, IBT operated the largest facility of its kind and performed more than one-third of all toxicology testing in the United States. IBT was later confirmed of engaging in extensive scientific misconduct and fraud, which resulted in the indictment of its president and several top executives in 1981 and convictions in 1983. The revelations of misconduct by IBT Labs led to reforms in the regulation of pesticides in the United States and Canada.

Pesticide regulation in the United States
Pesticide regulation in the United States is primarily a responsibility of the Environmental Protection Agency (EPA). In America, it was not till the 1950s that pesticides were regulated in terms of their safety. The Pesticides Control Amendment (PCA) of 1954 was the first time Congress passed guidance regarding the establishment of safe limits for pesticide residues on food. It authorized the Food and Drug Administration (FDA) to ban pesticides they determined to be unsafe if they were sprayed directly on food. The Food Additives Amendment, which included the Delaney Clause, prohibited the pesticide residues from any carcinogenic pesticides in processed food. In 1959, pesticides were required to be registered.
