Health-conscious shoppers often reach for Greek yogurt labeled “Only Natural Ingredients” or “Zero Sugar,” trusting those claims to guide everyday choices. For many parents, people managing diabetes or following keto-style diets, and anyone watching chemical exposures, those labels matter. In recent years, Chobani has faced class action litigation challenging exactly those marketing statements. This article explains the Chobani Yogurt Lawsuit developments involving phthalates and zero-sugar claims, what the allegations say, how regulators view the issues, and what the cases mean for consumers deciding what to put in their carts.
What Sparked the Chobani Yogurt Lawsuit Over Phthalates
In April 2025, a California consumer filed a putative class action against Chobani, LLC in the U.S. District Court for the Southern District of California. The case, known as Wysocki v. Chobani, LLC (Case No. 3:25-cv-00907), centered on two plain Greek yogurt products: Nonfat Plain and Whole Milk Plain. Both carried prominent “Only Natural Ingredients” claims on the front label and lid.
The plaintiff alleged that independent testing by PlasticList, published in late 2024, detected trace levels of phthalates in samples of those products. Phthalates are chemicals commonly used as plasticizers to make plastics more flexible. The lawsuit claimed these substances (including DEHP, DEP, and DEHT) likely migrated from the polypropylene containers into the yogurt. Plaintiffs argued that the presence of these synthetic chemicals contradicted the “Only Natural Ingredients” marketing and that Chobani should have disclosed them.
Chobani responded that its products contain only natural ingredients as labeled, that FDA has authorized certain phthalates for food-contact uses, and that the testing did not prove the specific products the plaintiff bought contained the chemicals. The company moved to dismiss the complaint.
Court Rulings and Current Status of the Phthalates Case
In April 2026, U.S. District Judge James E. Simmons Jr. largely denied the motion to dismiss. He allowed the core false advertising and express warranty claims to proceed, finding that a reasonable consumer could interpret “Only Natural Ingredients” as a promise that the yogurt did not contain synthetic plasticizers, even if those chemicals originated in packaging rather than being intentionally added as ingredients. The court dismissed some claims with leave to amend and noted the early stage of the litigation.
The plaintiff filed an amended complaint. On July 21, 2026, the parties jointly moved for voluntary dismissal, and the court granted the motion, terminating the case. No public class settlement, claim form, or payment program resulted from this action. Consumers should not expect checks or refunds from this particular lawsuit.
This outcome is common in food labeling cases. Many such suits settle confidentially, get narrowed, or end without a certified class or monetary relief for purchasers. The absence of a public settlement means no formal finding that the products were unsafe or that the labeling was unlawful.
Understanding Phthalates, Packaging, and “Natural” Claims
Phthalates are a family of chemicals used in many plastics and consumer products. Some function as plasticizers. FDA has long authorized limited food-contact uses of certain phthalates under its food additive regulations. The agency has also revoked authorizations for many phthalates after industry abandoned those uses, and it continues post-market review of remaining authorized applications. In 2026, FDA released evaluations examining whether certain phthalates should be grouped for cumulative risk assessment, reflecting ongoing scientific attention to the class.
Importantly, FDA does not authorize phthalates to be added directly to food. Detectable levels, when present, typically result from migration from packaging, processing equipment, or environmental sources. Trace amounts appear in many packaged foods, according to independent testing programs. PlasticList itself tested hundreds of products and found plastic-related chemicals widespread, including in yogurts and other everyday items. Consumer Reports and other groups have reported similar findings across the food supply.
The legal dispute was not primarily about whether phthalates are inherently unsafe at every detectable level. It was about whether the specific marketing claim “Only Natural Ingredients” becomes misleading when trace synthetic chemicals from packaging are present. Courts evaluate such claims from the perspective of a reasonable consumer under state consumer protection laws such as California’s Unfair Competition Law, False Advertising Law, and Consumers Legal Remedies Act. These statutes prohibit advertising that is false or likely to deceive.
What “Natural” Means in Food Labeling
FDA has not issued a formal definition of “natural” that fully resolves these disputes. The agency has stated that it considers “natural” to mean nothing artificial or synthetic has been included or added that would not normally be expected. Courts often look at the full context of the label, including ingredient lists and nutrition panels, when deciding whether a claim is misleading. Packaging migration cases raise a further question: does a chemical that enters the food after packaging count as an “ingredient”? The Wysocki court allowed that theory to proceed at the pleading stage, but the case did not reach a final merits ruling.
For everyday consumers, the practical takeaway is that “natural” claims remain a frequent target of class action litigation. Brands using strong natural messaging face heightened scrutiny when independent testing detects unintended substances.
The Zero Sugar Claims and Allulose Litigation
A separate line of cases targets Chobani’s Zero Sugar yogurt line. These products are sweetened with allulose, a naturally occurring monosaccharide (simple sugar) found in small amounts in some fruits and foods. Allulose provides sweetness with fewer calories and a lower impact on blood glucose than traditional sugars.
In 2023, consumers filed Franco v. Chobani, LLC in the Northern District of Illinois, alleging that labeling the product “Zero Sugar” or “sugar free” while including about four grams of allulose per serving was deceptive under numerous state consumer protection laws. Plaintiffs argued that allulose is a sugar under the plain language of FDA’s nutrition labeling regulation.
FDA regulation 21 C.F.R. § 101.9(c)(6)(ii) defines total sugars as the sum of all free mono- and disaccharides (such as glucose, fructose, lactose, and sucrose). Allulose is a monosaccharide. In 2020 guidance, FDA announced it would exercise enforcement discretion allowing manufacturers to exclude allulose from the “Total Sugars” and “Added Sugars” declarations on Nutrition Facts panels, while still counting it in total carbohydrates at a reduced caloric value of 0.4 kcal/g. The guidance reflected allulose’s different metabolic profile.
The district court dismissed the Franco case in May 2025, finding the state-law claims preempted by federal law and FDA’s approach. On July 27, 2026, the U.S. Court of Appeals for the Seventh Circuit reversed. The appeals court invited FDA’s views. FDA’s amicus brief took the position that the regulation’s definition of total sugars includes all monosaccharides, with the listed examples not limiting the category. The Seventh Circuit agreed, holding that allulose qualifies as a sugar under the regulation and that the plaintiffs’ claims seeking to enforce standards identical to the federal rule were not preempted. The case returned to the district court for further proceedings.
Chobani has maintained that the Nutrition Facts panel accurately reflects 0 g total sugar and 0 g added sugar consistent with FDA’s enforcement policy, and that allulose is a non-sugar sweetener in practical effect for labeling purposes.
Why Allulose Matters to Diet-Conscious Consumers
Many people buying “Zero Sugar” yogurt do so to manage blood sugar, follow low-carbohydrate diets, or reduce calorie intake. Allulose’s lower caloric contribution and minimal glycemic effect make it attractive for those goals. At the same time, the chemical classification as a monosaccharide creates tension between the strict regulatory definition and the agency’s practical enforcement guidance. The Seventh Circuit decision underscores that courts may prioritize the text of the regulation over guidance documents when deciding preemption questions.
As of September 2026, the Franco case remains active. No class has been certified, and no settlement has been announced. Similar allulose-related suits have been filed against other brands following the appellate ruling.
How These Cases Fit Into Broader Consumer Protection Trends
False advertising class actions involving food labels have become common. Claims often focus on terms such as “natural,” “healthy,” “no sugar,” or specific nutrient content statements. Plaintiffs typically seek damages measured by a price premium (the extra amount paid because of the allegedly misleading claim), injunctive relief requiring label changes, and attorney fees. Defendants raise defenses based on federal preemption under the Food, Drug, and Cosmetic Act, the lack of consumer deception when the full label is considered, and the scientific or regulatory status of the disputed substance.
Courts apply a “reasonable consumer” standard. They ask whether a significant portion of the general consuming public or of targeted consumers, acting reasonably under the circumstances, could be misled. Detailed ingredient lists and Nutrition Facts panels can sometimes cure front-of-package claims, but not always. Packaging migration theories and novel ingredients like allulose test the boundaries of these principles.
FDA remains the primary federal regulator of food labeling and food-contact substances. Its evolving positions on phthalates and allulose illustrate how science and policy develop over time. Consumers interested in primary sources can review FDA’s pages on phthalates in food packaging and its guidance on allulose declaration.
Practical Guidance for Consumers
What should a shopper do with this information?
First, read the full label. Front-of-package claims such as “Only Natural Ingredients” or “Zero Sugar” are marketing statements subject to legal challenge. The ingredient list and Nutrition Facts panel provide more complete information. For Zero Sugar products sweetened with allulose, the panel may show 0 g total sugars under FDA’s enforcement approach while still listing the sweetener in the ingredients.
Second, understand that detection of trace chemicals does not automatically equal a health risk or a legal violation. Many packaged foods contain low levels of substances that migrate from packaging. FDA continues to evaluate authorized uses of phthalates. Individuals with specific health concerns should consult physicians or registered dietitians rather than relying solely on lawsuit allegations.
Third, class action status updates change. As of the latest available information in September 2026, the phthalates case ended by voluntary dismissal without a public settlement. The zero-sugar allulose case is proceeding after the appellate victory for plaintiffs. No claim forms or payment deadlines currently exist for either matter. Websites that solicit “join the lawsuit” information should be approached carefully; many are marketing vehicles for law firms rather than official court notices.
Fourth, packaging choices can reduce certain exposures. Glass, stainless steel, or certain alternative plastics may limit migration of plasticizers, though no packaging is entirely free of potential interactions with food. Refrigeration and avoiding prolonged storage in plastic can also play a role for some products.
Finally, stay informed through reliable channels. Court dockets (available via PACER or free services such as CourtListener), FDA constituent updates, and reputable legal news sources provide primary information. Secondary articles sometimes overstate the existence of settlements or the certainty of health harms.
Consumer Rights and Next Steps If You Feel Misled
State consumer protection laws generally allow individuals to sue for false or misleading advertising. Successful claims can result in refunds, price-premium damages, or injunctive relief. Class actions can make it economically feasible to pursue small individual claims, but they also involve complex procedures, potential conflicts among class members, and the risk that a case ends without relief.
If you believe you purchased a product based on a specific claim that later proved inaccurate, keep receipts and product packaging when possible. Consult a consumer protection attorney for advice tailored to your situation and jurisdiction. Most class actions require no upfront payment from class members; counsel typically work on contingency. Be aware of statutes of limitations, which vary by state and claim type.
These lawsuits also serve a broader function. They put pressure on companies to substantiate marketing claims and on regulators to clarify ambiguous rules. Whether or not any particular case produces a large recovery, the cumulative effect can improve label accuracy over time.
Key Takeaways on the Chobani Yogurt Lawsuit
The Chobani Yogurt Lawsuit landscape involves distinct issues. One set of claims challenged “Only Natural Ingredients” labeling in light of alleged phthalate migration from packaging. That case reached a partial denial of a motion to dismiss before ending by voluntary dismissal in July 2026 without a public class settlement. A separate set of claims challenges “Zero Sugar” labeling of allulose-sweetened yogurt. The Seventh Circuit revived those claims in July 2026, holding that allulose falls within the regulatory definition of sugar, so the case continues.
Neither development establishes that Chobani products are unsafe. Both highlight ongoing debates about how consumers interpret marketing language, how packaging interacts with food, and how novel ingredients fit into existing nutrition labeling rules. Everyday shoppers benefit from reading full labels, understanding that “natural” and “zero sugar” remain contested marketing terms, and recognizing that most food-labeling class actions do not produce automatic refunds.
For the most current case status, check official court records. For questions about personal health or diet, speak with a qualified healthcare professional. Informed consumers remain the strongest check on marketing claims in the grocery aisle.
Frequently Asked Questions
Is there an active Chobani yogurt class action settlement I can claim?
No. The phthalates case (Wysocki) was voluntarily dismissed in July 2026 without a public settlement or claim form. The zero-sugar allulose case (Franco) is ongoing after the Seventh Circuit’s July 2026 decision, but no class has been certified and no settlement has been announced.
Did testing prove Chobani yogurt is unsafe?
No. The litigation relied on third-party testing that detected trace phthalates in samples. Detection of low levels is common across many packaged foods. FDA continues to authorize limited food-contact uses of certain phthalates and is conducting further safety reviews. The lawsuits focused on labeling claims rather than establishing specific health injuries from the products at issue.
Is allulose considered sugar under FDA rules?
The Seventh Circuit held that allulose is a monosaccharide and therefore falls within the regulatory definition of total sugars. FDA’s 2020 guidance continues to allow manufacturers to exclude it from the Total Sugars declaration under enforcement discretion because of its metabolic profile. The legal and practical labeling approaches are not identical.
Can I still buy Chobani products?
Yes. No recall or ban resulted from these cases. Consumers who prefer to avoid certain packaging materials or sweeteners can choose alternative products or formats (such as glass containers where available) based on personal preference.
What does “Only Natural Ingredients” legally mean?
FDA has not issued a comprehensive formal definition that resolves all disputes. Courts evaluate the claim from a reasonable consumer’s perspective in context. Packaging-migration theories remain litigable in some jurisdictions, but success is far from guaranteed.
How can I track future developments?
Monitor the federal court dockets for Franco v. Chobani and any newly filed related cases. FDA’s website publishes updates on phthalates and nutrition labeling. Reputable legal news outlets covering consumer class actions also report major rulings.
Should I keep receipts for yogurt purchases?
If you believe you have a strong individual claim under state consumer protection law, receipts and packaging can help document purchases. For most people, the practical impact of these cases will come through any future label changes rather than individual refunds.
