An infamous recall of Tylenol products occurred in September 1982 after seven people died from consuming cyanide-laced Tylenol capsules. Johnson & Johnson, the manufacturer of Tylenol, launched the recall, which encompassed 264,000 bottles of Tylenol.
Investigators think someone took the affected products from store shelves, laced them with the poison, and then returned them to the stores and pharmacies where the victims ultimately purchased and ingested them. Seven people ranging in age from 12 to 35 died as a result, including three members in one family.
The recall cost Johnson & Johnson more than $100 million. Despite the company’s offer of a reward for information leading to the apprehension of the person who tampered with the products, the case remains unsolved as of 2015.
