High Quality Content by WIKIPEDIA articles! Industrial Bio-Test Laboratories (IBT Labs) 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 suspected of engaging in in extensive scientific misconduct, or more properly, 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.
