Ultra Processed Food Lawsuits Face New Hurdle After Martinez Ruling

A judge's August 2025 dismissal of a 148-page complaint has set a new legal test that makes ultra-processed food litigation far harder.

The Martinez ruling of August 2025 has fundamentally reshaped ultra-processed food litigation by establishing that plaintiffs must provide far more detailed and specific allegations about which products they consumed, how often, and in what quantities. When U.S. District Judge Mia R. Perez dismissed *Martinez v. Kraft Heinz* in the Eastern District of Pennsylvania, she rejected a 148-page complaint that had named over 100 food brands without specifying which particular products the plaintiffs had actually consumed or when.

This decision created a new legal standard that has forced subsequent lawsuits—including newly filed cases in 2026—to rethink their entire litigation strategy. The hurdle is not theoretical. A 14-year-old who developed Type 2 Diabetes can no longer simply allege that he or she consumed “ultra-processed foods from Kraft Heinz and other manufacturers” and expect that claim to survive a motion to dismiss. Now, plaintiffs must identify the specific product (e.g., a certain brand of breakfast cereal or frozen meal), describe the consumption pattern with dates or frequency, and connect that consumption to the claimed harm. This shift from broad allegations to granular specificity has made it exponentially harder for plaintiffs’ attorneys to move these cases forward.

What Does the Martinez Ruling Actually Require?

Judge Perez’s August 2025 dismissal centered on a fundamental pleading problem: vagueness. The original complaint in *Martinez v. Kraft Heinz* named Kraft Heinz, Mondelez International, Coca-Cola, PepsiCo, General Mills, Nestlé USA, Kellogg’s, Mars, ConAgra Brands, and Post Holdings, but the plaintiffs had failed to allege which specific products from these manufacturers they had consumed. This is not a minor procedural oversight. Under federal pleading standards, a complaint must provide enough detail that the defendant can understand the claims against it and mount a defense. A defendant cannot meaningfully respond to “I ate ultra-processed foods” because the universe of such products is enormous and the causation theories might vary widely.

The ruling requires that ultra-processed food plaintiffs identify with specificity: (1) the exact product name and manufacturer; (2) the frequency and duration of consumption (e.g., “I consumed Product X three times per week for two years”); and (3) the quantity consumed. This mirrors the pleading standards in pharmaceutical mass torts, where claiming “I took a blood pressure medication that caused a heart attack” is insufficient—plaintiffs must name the specific drug, the dosage, the duration, and usually provide medical records confirming the diagnosis. For food products, where consumption is often sporadic and memory is unreliable, gathering this evidence before filing suit is difficult and expensive. The Martinez decision signals that judges will no longer tolerate “shotgun” complaints that throw multiple defendants and products at the wall hoping something sticks. Each allegation must have particularity. This is a significant departure from some earlier mass tort litigation where broad allegations were sometimes permitted to survive initial motion practice.

The New Pleading Standard and Its Burden on Plaintiffs

The specificity requirement created by Martinez places an immense investigative burden on plaintiffs’ counsel before filing suit. In a typical mass tort, attorneys identify potential claimants and file suit, then use discovery to develop the factual record. But the Martinez standard flips this process: plaintiffs must do substantial fact development before they can even file a complaint that will survive a motion to dismiss. This means retained nutritionists, food consumption records, purchase histories, and medical histories must all be assembled in advance. Consider a plaintiff who claims that consuming a certain brand of frozen pizza contributed to weight gain and Type 2 Diabetes. Under Martinez, the plaintiff must be able to show: which specific pizza product (not just “frozen pizza”), how many times per week it was consumed, for how long, in what portion sizes, and ideally contemporaneous evidence like grocery receipts, credit card statements, or family testimony.

Without this detail, the complaint will be dismissed before discovery even begins. A plaintiff who relies solely on “I remember eating this brand of pizza regularly” is unlikely to meet the new standard. This burden is not equally distributed. Wealthier plaintiffs with detailed medical records, stable residences, and preserved purchasing history are far more likely to meet the specificity requirement. A low-income plaintiff who moved multiple times, bought groceries from different stores, and did not keep detailed food diaries will find it nearly impossible to plead the kind of specific allegations the court now demands. There is a real risk that the Martinez standard, while facially neutral, creates a practical barrier to access for certain populations.

How Plaintiffs’ Lawyers Are Responding: New Cases and New Theories

Despite the Martinez hurdle, plaintiffs’ attorneys have not abandoned ultra-processed food litigation. Instead, they have adapted their strategies in two notable ways. In March 2026, Morgan & Morgan filed *Ford v. Kraft Heinz Company, et al.* on behalf of a 14-year-old plaintiff with Type 2 Diabetes. The Ford complaint appears to have learned from Martinez: rather than naming 100+ products, it likely focuses on a narrower set of specifically identified products tied to the individual plaintiff’s consumption pattern.

The case targets the same core defendants as Martinez but with a much tighter factual foundation. A different approach emerged in December 2025 when San Francisco City Attorney David Chiu filed *Chiu v. Kraft Heinz, et al.* using a public health legal theory rather than individual injury claims. This case alleges harm to the public as a whole—arguing that ultra-processed foods cause widespread disease in the San Francisco population—rather than proving causation in individual plaintiffs. The public health approach sidesteps some of the specificity problems by focusing on epidemiological evidence and population-level harm rather than requiring each plaintiff to prove exactly what they ate and when. This represents a meaningful tactical shift away from the traditional mass tort model that Martinez’s ruling has made impractical.

The Food Manufacturers Facing Current Litigation

The defendants in current ultra-processed food cases remain consistent: Kraft Heinz, Mondelez International, Coca-Cola (which acquired Post Consumer Brands), PepsiCo, General Mills, Nestlé USA, Kellogg’s Company (which split into WK Kellogg Co. and Kellanov), Mars Wrigley, ConAgra Brands, and Post Holdings. These manufacturers represent the vast majority of ultra-processed food sales in the United States and control hundreds of billions of dollars in annual revenue across thousands of products. A significant legal victory—or a series of adverse rulings—could expose each of these companies to substantial liability. The exposure varies by manufacturer.

Kraft Heinz, for instance, produces shelf-stable sauces, processed meats, and prepared meals that are central to the litigation’s focus on ultra-processed foods. PepsiCo faces claims related to its extensive snack food portfolio and sugary beverages. General Mills has heavy exposure in breakfast cereals. The variation in risk partly depends on each company’s specific product mix and how clearly those products fit the definition of ultra-processed foods—a definition that remains contested. Some defendants argue that many of their products contain whole grain, vitamins, and minerals and therefore should not be categorized as purely ultra-processed, while plaintiffs’ attorneys counter that the added sugars and sodium content make them effectively ultra-processed regardless of fortification.

Procedural Obstacles and the Long Road Ahead

Beyond the Martinez specificity requirement, ultra-processed food plaintiffs face several additional hurdles. First, establishing causation remains legally difficult. A plaintiff with Type 2 Diabetes must prove not merely that she ate ultra-processed foods, but that consuming those foods—rather than genetics, overall caloric intake, sedentary lifestyle, or other factors—caused her diabetes. Food defendants will likely argue that no single food category caused the injury and that multiple confounding factors make causation unprovable. Courts have historically been skeptical of food-based causation claims absent robust epidemiological evidence or clear labeling failures.

Second, the statute of limitations creates timing problems. Many ultra-processed food products have been on the market for decades, and consumers may not discover they have disease for years or decades after consumption. A claim that might have accrued in 2000 may not be discovered until 2020, and filing in 2023 could be barred by a three-year statute of limitations depending on the jurisdiction. This limitation is particularly harsh for chronic diseases like Type 2 Diabetes, which develop gradually and are often attributed to age or lifestyle rather than diet. Some jurisdictions allow a “discovery rule” that tolls the statute until the plaintiff discovers the link between the product and the injury, but not all do, and litigating the discovery rule itself is expensive.

Settlement Expectations and Litigation Timeline

No meaningful settlements are expected in 2026 for ultra-processed food cases. The litigation remains in early stages, with dismissal motions still being adjudicated and the law still being developed by courts nationwide. Food manufacturers have strong incentives to fight aggressively at the pleading stage—settling before cases can even survive a motion to dismiss would signal weakness and could encourage a wave of new filings.

Additionally, the Supreme Court’s heightened pleading standards in recent years have empowered defendants to obtain early dismissals, and food manufacturers will use every available tool to prevent cases from reaching discovery, where the cost of defending multiple cases simultaneously becomes astronomical. However, a small number of cases may settle by late 2026 if plaintiffs’ counsel can develop sufficiently specific factual allegations to survive a motion to dismiss. Morgan & Morgan’s Ford case and other similarly focused cases may reach a point where defendants calculate that settlement makes sense from a business perspective. But these settlements, if they occur, will likely be limited and will not signal a broader shift in the litigation landscape.

What the Martinez Standard Means for the Future of Food Litigation

The Martinez ruling establishes a precedent that will influence food litigation for years to come. Any future attempt to sue food manufacturers for health harms—whether based on ultra-processed foods, added sugars, salt content, or novel food additives—will need to clear the same specificity hurdle that derailed the original Martinez complaint. This does not mean such lawsuits cannot succeed, but it does mean they will be more expensive, more time-consuming, and more difficult to bring to court on behalf of large classes of claimants. The ruling also incentivizes different litigation strategies.

The Chiu public health case in San Francisco demonstrates one alternative: rather than suing on behalf of individuals harmed by specific products, attorneys can pursue claims on behalf of a population or jurisdiction harmed by the category of ultra-processed foods generally. If successful, this approach could bypass some of the causation and specificity problems that plagued Martinez. However, these public health cases also face significant legal obstacles, including questions about standing, sovereign immunity (in the case of government plaintiffs), and whether public health law provides a viable theory of recovery for the harms ultra-processed foods cause. The litigation landscape for food manufacturers has shifted, but the ultimate trajectory remains uncertain.
