In late-September 1982, several Extra-Strength Tylenol capsules around the Chicago-area were laced with cyanide, killing seven people in the area. Johnson & Johnson quickly responded to the incidents, and on October 5th, 1982, they recalled nearly 31 million bottles around the United States. This incident resulted in the development of the triple tamper-evident seal, which has become the standard on consumer products to this day. This recall is considered one of the biggest product recalls in United States history to this day.
