San Francisco hauled 10 of the country’s biggest food manufacturers into court on Tuesday, filing what city officials describe as a first-of-its-kind lawsuit that blames ultra-processed foods for fueling a local public health crisis. City lawyers say they want to stop deceptive marketing, require health warnings, and recoup money the city claims it has spent treating diet-related disease.
The case, filed in San Francisco Superior Court by City Attorney David Chiu, names Coca-Cola, PepsiCo, Kraft Heinz, Mondelez, General Mills, Nestlé, Kellogg/Kellanova, Mars, Post Holdings and Conagra, according to a press release from the San Francisco City Attorney’s Office. The city says the complaint alleges violations of California’s Unfair Competition Law and the state public nuisance statute, and it seeks injunctions, restitution and civil penalties. The full, 64-page complaint lists dozens of brands the city classifies as ultra-processed.
“These companies created a public health crisis,” City Attorney David Chiu said at a news conference announcing the filing, calling some products “unrecognizable and harmful to the human body.” Mayor Daniel Lurie and the city’s public-health director backed the legal move, saying it is meant to protect families and curb marketing aimed at children and vulnerable communities. The City Attorney’s press release, posted by the San Francisco City Attorney’s Office, includes the full set of statements from local officials.
What the complaint alleges
The complaint portrays ultra-processed foods, or UPFs, as industrial formulations that alter the physical and chemical structures of food in ways that promote overconsumption. It ties those products to rising rates of obesity, diabetes, fatty-liver disease and certain cancers.
San Francisco’s filing names dozens of brand examples, such as Oreos, Cheerios, Pop-Tarts, Lunchables, Slim Jim and Coca-Cola beverages, and traces what it describes as decades of marketing strategies aimed at children and communities of color. The city is asking the court to block what it calls deceptive advertising, require consumer education and health warnings, and impose financial penalties that would help offset local health care costs.
Industry pushback
The food industry’s main trade group is pushing back, arguing that the very idea of “ultra-processed” is not settled science and that manufacturers have already moved to clean up many products. The AP News quoted Sarah Gallo of the Consumer Brands Association saying there is “no agreed-upon scientific definition of ultra-processed foods” and pointing to lower-sugar, lower-sodium and no-synthetic-color versions of many items on store shelves. Several defendants had not offered immediate comment to reporters, Reuters noted.
Legal hurdles and precedent
San Francisco has hired outside counsel with experience in large corporate litigation, but legal experts say the city faces a familiar challenge: proving that specific corporate practices caused specific harms. Reporting and analysis from Reuters and other legal observers note that courts have already pushed back on sweeping ultra-processed food claims.
In a closely watched earlier case, a federal judge in Philadelphia tossed a private lawsuit for failing to link particular products and consumption patterns to a plaintiff’s diabetes and liver disease. Legal commentary at Kilpatrick, summarized on JDSupra, highlights the ruling’s focus on causation and notice requirements.
Why the city acted now
The lawsuit arrives as federal and state policymakers put increasing scrutiny on ultra-processed foods. A CDC analysis this year reported that Americans get more than half their calories from UPFs, raising pressure on regulators and local governments. The AP summarized the CDC findings.
California has already begun to move on its own. In October, the state enacted what it called a first-in-the-nation law that directs agencies to identify and phase out the most concerning ultra-processed foods from school meals. The bill text and implementation timeline are posted by the Governor’s Office.
What happens next
The food companies are expected to file motions to dismiss or seek to move the case, and even if the lawsuit survives that first round, it could take years before discovery or trial. Industry lawyers are already pointing to recent dismissals in related cases as a blueprint for defense strategy, while public-health advocates say the mere filing could spur changes to advertising and product formulas long before any final judgment.
For now, the case is titled People of the State of California v. Kraft Heinz Company, Inc., et al., filed Dec. 2 in San Francisco Superior Court. Trade and industry coverage, including detailed brand lists and argument summaries, is available from Food Business News.
