Gavin Newsom vetoed a California bill that was set to ban the sale of cookware and other consumer goods manufactured with Pfas, also known as “forever chemicals”, human-made compounds linked to a range of health issues.

The governor’s decision on Monday followed months of debate and advocacy, including from high-profile celebrity chefs such as Thomas Keller and Rachael Ray, who argued that nonstick cookware made with Pfas, when manufactured responsibly, can be safe and effective and urged lawmakers to vote against the proposal.

Newsom said in a statement that the legislation was “well-intentioned” but would affect too broad a swath of products and would result in a “sizable and rapid shift” of cooking products available in the state.

“I am deeply concerned about the impact this bill would have on the availability of affordable options in cooking products,” Newsom wrote, adding that the state “must carefully consider” the consequences of a dramatic shift in available products.

Concerns over the use of Pfas, chemicals used to make cookware and other items non-stick and water-resistant, have grown significantly in recent years. Called “forever chemicals”, because they do not break down naturally, Pfas are used in non-stick cookware, waterproof mascara and dental floss, among other items.
