A class action lawsuit alleges that Chosen Foods misrepresents its avocado oil as 100 percent pure. The complaint follows a University of California Davis study that reportedly found authenticity failures in the company's products.
Why it matters
Consumers often choose premium avocado oil for its specific nutritional profile, but the lawsuit contends that products may be diluted with cheaper seed or vegetable oils. This legal action challenges the reliability of purity claims on food labels.
A University of California Davis study of avocado oil, initiated in 2020 and released in July 2026, found that eight out of eight tested lots of Chosen Foods products failed authenticity testing. The full extent of the adulteration remains under investigation.
The players
Chosen Foods
A food manufacturer that markets avocado oil and other health-focused pantry staples.
Texas Attorney General
The state authority currently conducting an investigation into avocado oil purity standards.
University of California Davis
A research institution that conducted an authenticity study of commercial avocado oils.
Karoline Hebert
The plaintiff who filed a class action lawsuit against Chosen Foods in Louisiana.
The details
The lawsuit alleges that premium avocado oil is being substituted with or diluted by lower-cost refined vegetable and seed oils. It further contends that the company's internal purity testing either did not occur or was insufficient to detect this adulteration. These practices, if proven, would mean consumers were misled into paying premium prices for an impure product.
Timeline

Health Landscape
The lawsuit reflects a growing focus on the transparency and accuracy of oil labeling in the United States. It marks a significant push to ensure that premium pantry staples align with their advertised purity standards.
If you prioritize specific oils for their healthy fat profiles, you may want to monitor the results of the Texas Attorney General's investigation. It is always helpful to discuss concerns about product labels or nutritional quality with your primary care provider.
The takeaway
When choosing oils, look for independent seals or verified testing if you are concerned about potential adulteration. If you have questions about which cooking fats best support your dietary goals, consult a registered dietitian.
