Monsanto's 'cancer-causing' weedkiller destroyed my life, dying man tells court

Testifying in landmark trial, former school groundskeeper describes suffering allegedly caused by company's chemicals

Dewayne Johnson said that if he had known what he knew now about Roundup weedkiller, "I would've never sprayed that product on school grounds " if I knew it would cause harm " It's unethical."

Johnson, a former school groundskeeper in northern California who is terminally ill, was testifying on Monday in his landmark suit against Monsanto about the cancer risks of the company's popular weedkiller. He is the first person to take the agrochemical company to trial over allegations that the chemical sold under the Roundup brand is linked to cancer.
