(NEXSTAR) - Two California lawmakers are leading the charge in Congress to push the FDA to set national standards for olive oil. "Olive oil is something that everyone loves," Rep. David Valadao (R-CA) said. But California Congressmen David Valadao and Josh Harder say there aren't clear labeling standards for olive oil, which means you might not always be buying what you think you are. "It could be good. It could not be good. It could be adulterated. It could be saying it's something else," said Harder (D-CA). The Republican and Democrat represent California counties that lead the nation in olive oil production. They're pushing to pass their "Olive Oil Standards Act" to require the FDA to create identity and grade standards for the product. Valadao, who's a dairy farmer, says it's overdue. "This is something we've had for years with the dairy industry. If a consumer goes and buys cheddar cheese, mozzarella or whatever dairy product, the standards of identity are there to protect the consumer," Valadao said. And with the administration's new dietary guidelines recommending olive oil as a healthy fat, Joseph R. Profaci with the North American Olive Oil Association is optimistic the FDA takes action. "This is olive oil's moment in the sun," Profaci said. But when it comes to what you buy on store shelves, Profaci says his association found in a 2024 study that 85% of the olive oil market didn't have other ingredients or adulterants like seed oils mixed in. "It's largely a perception more than a reality when it comes to retail," Profaci said. Profaci says that's not always the case though when it comes to food service. He says a national standard is needed, which is why the NAOOA has petitioned the FDA for one for years. "Consumers deserve to have full faith and confidence that what they're buying is consistent with the label," Profaci said.
