Glyphosate, the active ingredient in Monsanto’s Roundup, will be added to the list of chemicals California warns are known to cause cancer.

The state’s Office of Environmental Health Hazard Assessment has posted a notice on its website that glyphosate will be added to the list on July 7. A California judge denied Monsanto's request to block the state from doing so, but the company has filed an appeal.

A study at Webster University has revealed that Monsanto's weed killer Roundup can significantly change ant behavior.

Researchers began two years ago to study how ants are affected by man-made contaminants, including Roundup. The product has become controversial recently due to allegations that its key ingredient, glyphosate, causes cancer in humans.

The ant study hasn't been published yet, but student researchers noted that the herbicide significantly affected western harvester ants.

Monsanto is facing more pressure to compensate farmers and farm workers who allege that its leading pesticide product caused them to develop cancer. 

A Los Angeles-based law firm on Friday filed 136 new cases against the company in St. Louis County Circuit Court. The lawsuits allege that exposure to glyphosate, the active ingredient in Roundup, caused the plaintiffs to develop non-Hodgkin's lymphoma.

The debate over the safety of Monsanto’s weed killer Roundup has become more complicated, as newly released emails suggest the company had ghostwritten scientific research on glyphosate, the pesticide’s key ingredient.

An international panel of scientists reported this week that glyphosate, the main ingredient used in Monsanto's weed killer Roundup is unlikely to cause cancer in humans.
