Judge will let experts testify that Roundup linked to cancer

A judge in San Francisco says evidence seems weak that Roundup weed killer causes cancer, but experts can still make that claim at trial.

The ruling Tuesday by U.S. District Judge Vince Chhabria allows hundreds of lawsuits against Roundup’s manufacturer, Monsanto, to move forward. The lawsuits by cancer victims and their families say the agrochemical giant long knew about Roundup’s cancer risk but failed to warn them. Monsanto has vehemently denied such a connection.
