A Santa Fe County man has joined hundreds of other plaintiffs around the nation who are suing agricultural products giant Monsanto, claiming they got cancer from using Roundup, a weedkiller the company has hailed for decades as being as “safe as table salt.”

The complaint says Edwin Slominski, 84, of Edgewood “avoided most pesticides and herbicides out of concern they could be toxic.” But beginning in 2000, Slominski’s suit says, he used 3 or 4 gallons of Roundup a year to kill weeds in his driveway.

Roundup was supposed to be harmless to humans, according to his complaint, filed last month in the U.S. District Court. “The truth, however, is far more insidious. The active chemical in Roundup, glyphosate, is a carcinogen, and Monsanto has known this fact for decades,” he says in the suit.
