Gov. Gavin Newsom on Monday vetoed legislation that would have phased out a range of popular consumer products, including nonstick pots and pans, that contain synthetic chemicals with potential links to cancer.

"I appreciate the efforts to protect the health and safety of consumers, and while this bill is well-intentioned, I am deeply concerned about the impact this bill would have on the availability of affordable options in cooking products," Newsom wrote in his veto statement. "I believe we must carefully consider the consequences that may result from a dramatic shift of products on our shelves."

The legislation would have prohibited the selling or distributing of cookware with intentionally added perfluoroalkyl and polyfluoroalkyl substances, known as PFAS, by 2030. It phased out PFAS in products for infants and children, ski wax, dental floss, food packaging and cleaning products starting in 2028. Previously used items would have been exempt.

Sen. Ben Allen (D-Santa Monica), who introduced the legislation, Senate Bill 682, said he will continue to work on the issue moving forward.

"We are obviously disappointed," he said. "We know there are safer alternatives -- (but) I understand there were strong voices on both sides on this topic."

Allen previously explained he introduced the bill to help protect the state's water supply from contamination.

A study released in 2023 by the U.S. Geological Survey found tap water in urban areas of Southern and Central California is more likely to contain PFAS than the drinking water in most of the nation's other regions.

"The water agencies, sanitation agencies and local governments are faced with increasingly impossible-to-meet standards just to keep the water supply for our constituents clean," Allen said during a Senate committee meeting in April. "They're facing the costs while the producers who keep pushing these products out on the market are not being held accountable."

PFAS are commonly dubbed "forever chemicals" because of their well-established longevity. They are linked to adverse health effects, including liver enzyme changes and kidney and testicular cancer, according to the U.S. Centers for Disease Control and Prevention.

The chemicals have been used for decades to prevent food from sticking to pans or packaging, or to make materials more resistant to stains. California has taken steps in recent years to ban their use in certain items, like cosmetics and menstrual products.

Dozens of organizations weighed-in on Allen's bill, with the Sierra Club, California Health Coalition Advocacy and the League of California Cities supporting the legislation.

The Chemical Industry Council of California and the Cookware Sustainability Alliance were among those opposed.

Steve Burns, president of the sustainability alliance, was especially concerned by the provision barring the distribution of the banned products.

"California is the entry point for nonstick cookware and other products that come into the Port of Long Beach, the Port of Los Angeles or the Port of Oakland, and then get distributed throughout the country," he told the Times. "They go to warehouses, distribution centers and get loaded up on rail or usually trucks -- so there's a lot of jobs in the California economy that depend on products that have Teflon."

Burns said science hasn't shown that all PFAS are harmful and argued California should have studied the issue further. He pointed to Illinois, which recently passed similar legislation but ultimately nixed the line banning nonstick cookware. An amendment instead directs the Illinois Environmental Protection Agency to assess scientific data on fluoropolymers, the type of PFAS used in nonstick pots and pans.

Several states have recently moved toward restricting items with PFAS. Last January, Minnesota became the first state to ban PFAS in cookware. The Cookware Sustainability Alliance filed a lawsuit arguing the law discriminated against out-of-state commerce. A judge dismissed the suit in August.

The sustainability alliance has shared letters of opposition on its website from several prominent chefs and culinary personalities, including cook and television host Rachael Ray and Mark Dommen, the chef at Hestan, a new restaurant in Napa slated to open later this year.

Dommen explained the legislation would have placed an unfair burden on restaurants and food service providers.

"Non-stick cookware is essential to our daily operations and eliminating these products without a viable alternative would drive up costs, disrupt our supply chain, and put California restaurants at a competitive disadvantage," Dommen wrote.

Ray, who has a cookware line, argued easy-clean cookware helps families eat healthier by making it easier to prepare meals without extra oils or fats.

Her letter drew a gentle rebuke from actor and environmental activist Mark Ruffalo, who implored Ray on social media to reconsider her stance and said her advocacy on behalf of the cookware industry was putting the bill in jeopardy.

"Some of us have so much PFAS in our blood that we face a far greater risk of developing cancer," he wrote in a recent letter shared on X. "Let's work together to get PFAS out of the everyday products we bring into our home."

Scientific studies about the health effects of PFAS will continue, according to the CDC.

"Ongoing research has identified associations between PFAS exposure and several health impacts," the agency's website states. "There are many factors that can influence the risk of these effects, such as exposure, individual factors and other health determinants. Research is ongoing to understand the mechanisms of PFAS toxicity."
