Michigan has become the second US state to introduce legislation that would allow it to ban the sale of genetically modified fish.
But, bizarrely, it is not intending to apply it to the sale of Glofish, according to a report in The Bay City Times.
The new bill would allow the Michigan Departments of Natural Resources (DNR) and Agriculture to any ban genetically modified organisms (GMOs) in the state, making it an offence to keep, sell or release any GMO.
Brad Wurfel of the DNR told The Bay City Times: "The DNR is not worried about the Glofish themselves, but this technology could be applied to other species that could threaten Michigan's existing aquatic species, so what this does is give the state the authority to protect species here."
The DNR believes that Glofish pose no environmental threat. California banned the sale of the fish on ethical grounds.
