The concept of quality goes hand and hand with consumer safety. In the United States, Congress passed the Pure Food and Drug Act in 1906, which made it (for the first time) illegal to sell contaminated food and also required truthful labeling on drugs. It was the beginning of government oversight over the food and drug industries. Subsequent regulations required manufacturers to establish a quality management system (QMS system) to ensure product quality and safety. The QMS software in the market today is based on the same belief that quality is essential to consumer safety.
