A new GMO corn protein no longer needs a safety limit from US regulators

US environmental regulators have exempted a new genetically modified corn protein from safety limits. This means corn engineered with this protein can be sold without a maximum permissible level for its residues in food.

For decades, any new genetically modified organism (GMO) in food had to prove its safety by establishing a 'tolerance' — a maximum allowable level of the new substance. This exemption means that for this specific protein, the regulators decided no such limit is needed. This could make it faster and cheaper for companies to bring new engineered crops to market, as they avoid a significant regulatory hurdle.
