People in the U.S. who bought Chosen Foods avocado oil, spray, mayonnaise or dressings labeled “100% Pure Avocado Oil” since June 6, 2023 may be covered by a proposed class action alleging the products contain cheaper seed oils, after a UC Davis study found all four Chosen Foods mayos and dressings it tested inconsistent with authentic avocado oil. No class has been certified and there is nothing to claim yet.

What Is the Chosen Foods Avocado Oil Lawsuit?
Chosen Foods, which markets itself as “America’s #1 Avocado Oil,” faces a proposed class action alleging that products it labels “100% Pure Avocado Oil” contain, or risk containing, cheaper seed oils such as canola, soybean, sunflower or safflower. The case is Hebert v. Chosen Foods LLC, No. 2:26-cv-01908, before U.S. District Judge Greg Gerard Guidry in the Eastern District of Louisiana.The suit was filed August 28, 2026 and replaced with a first amended complaint on September 4. It builds on a July 2026 UC Davis study that tested avocado oil-labeled mayonnaise, dressings and chips. Chosen Foods has disputed the study and says it never adds seed oils, and none of the claims has been proven.

What the UC Davis Study Found
According to the complaint, the same UC Davis research group whose 2020 study Chosen Foods has long cited in its marketing published a new peer-reviewed study in Applied Food Research online on July 11, 2026. This time the researchers tested processed foods that list avocado oil or olive oil as their only oil, buying 37 products in two separate production lots each and comparing their fatty acid and sterol profiles with the international Codex standard for avocado oil adopted in November 2024.The complaint describes these results:
- Chosen Foods: all four Chosen Foods products tested — Classic Mayo, Vegan Mayo, Lemon Garlic Dressing & Marinade and Zesty Italian Dressing & Marinade — were classified as inconsistent with authentic avocado oil in both lots, eight samples out of eight.
- Avocado oil foods overall: 48 of 54 avocado oil-labeled samples, or 89%, failed, including 93% of chip samples, 71% of mayonnaise samples and every salad dressing sample.
- Olive oil controls: only 1 of 20 olive oil-labeled samples failed under the same method.
The other avocado oil suits OCA is tracking rest on the same research, including cases against Siete, Simply Tostitos, Sprouts and Utz.
Chosen Foods’ Response and the Texas Investigation
According to the complaint, Chosen Foods publicly disputed the study’s suggestion that its two mayos and two dressings contain seed oils, said it never adds seed oils of any kind, and said the study’s testing did not fully account for finished products like condiments and dressings. The company also said it uses “the same pure avocado oil” in its mayonnaise and dressings as in its cooking oils, and that its avocado oil has been tested for purity internally and by third parties for years.The plaintiff treats those statements as the core of the case. If one tested oil supply feeds the whole line and the finished products failed, the complaint argues, either the testing did not happen as described or it did not catch what UC Davis found, and the “guaranteed” purity claim was misleading across every product. Those are the plaintiff’s arguments, not findings.
The complaint also says that on August 20, 2026, Texas Attorney General Ken Paxton announced an industry-wide investigation into products marketed as made with avocado oil, and that Chosen Foods, Primal Kitchen and Siete Foods received civil investigative demands under the Texas Deceptive Trade Practices Act. An investigation is not a finding of wrongdoing.
Which Products and Buyers Are Covered
The plaintiff, a Louisiana shopper, says she bought Chosen Foods 100% Pure Avocado Oil Spray in New Orleans for $14.79 a unit and bought Classic Mayo on several occasions, all before the study came out. Classic Mayo is one of the four products UC Davis tested. The complaint acknowledges that the spray itself has not been independently tested; it alleges the spray draws on the same oil supply and is sold under the same purity guarantee.The first amended complaint proposes two groups:
- Nationwide class: people and entities in the United States who bought Chosen Foods avocado oil-labeled products bearing the “100% Pure Avocado Oil” representation, including bottled oil, spray, mayonnaise and dressings and marinades, from June 6, 2023 through the filing of the complaint.
- Louisiana subclass: the same purchases made in Louisiana.
The Claims and What the Plaintiff Wants
The amended complaint brings seven counts: breach of express warranty; redhibition under Louisiana law, which lets buyers seek a price reduction or a refund for hidden defects; the Louisiana Unfair Trade Practices Act (pleaded individually and, in the alternative, for the subclass); fraudulent misrepresentation; fraud in the inducement; negligent misrepresentation; and unjust enrichment for buyers outside Louisiana.It seeks damages including the price premium paid, rescission and refunds for Louisiana buyers, and an order requiring Chosen Foods to stop using “100% Pure Avocado Oil” and “guaranteed” pure claims unless independent testing supports them, to disclose the oils in its products, to adopt independent third-party testing rather than relying on suppliers’ certificates of analysis, and to run corrective advertising.
What Happens Next
The case is assigned to Judge Guidry, with Magistrate Judge Michael North handling referred matters. Chosen Foods asked for more time to respond to the amended complaint on September 29, and the court granted it on September 30. A response, often a motion to dismiss in labeling cases, would come next.Read the Complaint
