The Avocado Oil Racket Hiding on Grocery Shelves

You Paid a Premium for the Good Stuff. New Testing Says You May Have Brought Home Cheap Oil in a Fancy Bottle

Out here on the homestead, we work hard to keep questionable food off the supper table. We turn the soil, raise what meat we can, preserve the garden harvest, and read ingredient labels with the suspicion of a farmer watching storm clouds stack up in the west.

So it stings to learn that the expensive bottle of avocado oil sitting beside the cast-iron skillet may not be what the label promises.

In a landmark investigation, researchers at the University of California, Davis, tested commercial avocado oils sold across the United States. Their 2020 study found that at least 82 percent of the samples were either stale before their expiration date or mixed with other oils.

Even worse, three bottles labeled “pure” or “extra virgin” contained oil that was nearly 100 percent soybean oil.

That isn’t a small labeling mistake.

That’s somebody selling the mule and calling it a racehorse.

The Trouble Didn’t End With One Study

Naturally, researchers wanted to know whether grocery-store brands were any better. So UC Davis went back to the laboratory and tested 36 private-label avocado oils sold by 19 retailers in the United States and Canada.

The 2023 results were nearly as troubling. Only 31 percent of the samples were judged pure, while just 36 percent met the quality advertised on the label.

In other words, roughly seven out of ten private-label oils failed either the purity test, the quality test, or both.

Researchers also found that extremely cheap avocado oil was more likely to be adulterated. That makes sense when you stop and think about it. Avocado oil is costly to produce, so a bargain-basement price should raise the same suspicion as a stranger offering you a nearly new tractor for five hundred dollars.

Still, price alone won’t protect you. UC Davis food scientist Selina Wang has warned that while an unusually low price can be a red flag, an expensive bottle isn’t automatically pure.

The label can fool you. The price can fool you. Sometimes even the color and smell can fool you.

Now the Trouble Has Spread Beyond the Bottle

More recently, researchers began looking at foods advertised as being made with avocado oil—chips, mayonnaise, and salad dressings that often command a hefty premium.

The findings were worse than most folks expected.

According to a July 2026 UC Davis report, researchers tested 54 processed foods labeled as containing avocado oil. They found that 48 appeared to contain cheaper oils that weren’t declared on the label.

That included 93 percent of the chips, 71 percent of the mayonnaise, and every avocado-oil salad dressing examined.

The study covered only a portion of the market, so it doesn’t prove that every product on every shelf is adulterated. Still, the pattern is hard to ignore. The problem that first showed up in glass bottles has apparently wandered into the snack aisle, the condiment shelf, and the refrigerator door.

Meanwhile, the FDA itself has identified the adulteration of expensive oils—including avocado oil—as an area needing additional investigation. Yet consumers are still shopping in a market without a strong, enforceable standard defining exactly what avocado oil should be.

That leaves plenty of room for cloudy labels and questionable suppliers.

There May Be More Than Cheap Oil in the Bottle

Purity isn’t the only concern.

In a separate investigation, consumer watchdog Mamavation worked with Defend Our Health and an EPA-certified laboratory to test popular avocado oils for phthalates. These chemicals are commonly associated with plastics and may enter food through tubing, storage equipment, processing materials, caps, seals, or packaging.

The Mamavation avocado-oil investigation reported measurable phthalates in every product tested, although the amounts varied dramatically.

That doesn’t prove the oil itself was fake, and it doesn’t establish exactly where the phthalates entered each product. Purity testing and phthalate testing measure two different problems. Still, the findings show why words such as “natural,” “clean,” and “pure” shouldn’t be treated like laboratory certificates.

A green leaf on the label doesn’t tell you what happened inside the processing plant.

The Brand Names Showing Up in Tests and Lawsuits

Several familiar brands have appeared in independent testing, false-labeling lawsuits, or both. However, there’s an important fence post to drive into the ground here: a lawsuit contains allegations, not a final finding of guilt.

For example, Mamavation reported 2,774 parts per billion of total phthalates in Primal Kitchen Pure Avocado Oil. Contrary to some online claims, Primal Kitchen is owned by Kraft Heinz—not Nestlé. The reported phthalate result also doesn’t, by itself, prove that the oil was diluted with soybean, canola, or another cooking oil.

Kroger’s Private Selection avocado oil recorded 3,032 ppb in the same phthalate investigation. Separately, a false-advertising case involving Private Selection alleged that testing found fatty-acid and sterol patterns inconsistent with pure avocado oil.

Meanwhile, lawsuits have challenged avocado oils sold under Walmart’s Great Value label and Aldi’s Simply Nature label. The Great Value complaint alleged that the product wasn’t as pure as advertised, while the Aldi lawsuit alleged the presence of undisclosed sunflower and safflower oils.

Likewise, a 2024 lawsuit involving Target’s Good & Gather oil accused the retailer of selling oil mixed with undisclosed lower-cost oils. Sprouts Farmers Market has faced a similar complaint alleging that its “pure” avocado oil contained canola oil.

Sam’s Club’s Olivari avocado oil has also been the subject of false-labeling litigation, although the company moved to dismiss the case. As with the others, allegations made in a complaint shouldn’t be repeated as though a judge or jury has already settled the facts.

Finally, Mamavation reported 2,426 ppb of total phthalates in Trader Joe’s All Purpose Avocado Oil.

These names matter because families recognize them. Still, the fair conclusion isn’t that every bottle from every one of these brands is counterfeit. Products, suppliers, factories, and batches can change, and court allegations may be disputed or dismissed.

The more honest conclusion is simpler: don’t give any brand a lifetime pass.

Two Oils That Passed the UC Davis Test

Thankfully, the original UC Davis investigation did find a couple of bright spots.

Chosen Foods and Marianne’s were the only two brands in that particular study whose refined avocado-oil samples were both pure and nonoxidized. That makes them reasonable starting points for shoppers, although it isn’t a guarantee covering every bottle, batch, or future production run.

It’s also important to keep purity separate from other concerns. For instance, Chosen Foods passed the UC Davis purity and oxidation testing, but Mamavation later reported 1,130 ppb of total phthalates in the Chosen Foods bottle it examined.

One test asks, “Is this really avocado oil?”

The other asks, “Did plastic-associated chemicals show up in this particular sample?”

Those aren’t the same question.

When choosing a producer, look for a company that explains where its avocados come from, how the oil is processed, and whether batches are independently checked for fatty-acid and sterol composition. A company willing to publish recent, lot-specific laboratory results gives you more useful information than one leaning on pretty pictures and words such as “premium.”

Don’t Judge Every Oil by Its Color

Here’s where some popular kitchen advice runs off the road.

Unrefined or extra-virgin avocado oil usually carries a green hue from chlorophyll and other pigments. It may also have a grassy, buttery, or mushroom-like aroma.

Refined avocado oil is different. Refining removes much of the color, odor, and flavor, so authentic refined oil can be pale yellow and nearly neutral-smelling.

That means a clear-looking bottle isn’t necessarily fake, just as a beautiful green bottle isn’t necessarily pure. A dishonest producer can adjust appearance, and a legitimate producer may sell a properly refined oil with very little color.

So read what the bottle actually claims to be. Don’t compare refined oil with extra virgin and assume one must be fraudulent because they look different.

How to Shop Like a Homesteader

First, be suspicious of oil priced far below comparable products. UC Davis found that extremely low-cost private-label oils were more likely to be adulterated, although a high price is no guarantee of honesty.

Next, choose packaging that protects the oil. Dark glass or a well-sealed metal container helps shield it from light. If you buy refined oil in plastic, avoid bottles that have been sitting in direct sunlight or near a hot store window.

Then, buy only what your household will use within a reasonable time. A giant jug may look like a bargain, but every opening brings in fresh oxygen. If that container sits beside the stove for the better part of a year, heat, light, and air will slowly work against it.

Once home, keep the bottle tightly closed in a cool, dark cupboard—not on the sunny windowsill and not next to the range.

Also, check for a production or harvest date when available. A “best by” date is useful, but it doesn’t tell you how long the oil sat in a warehouse before reaching your pantry.

Finally, pay attention after opening. If an oil develops a stale, waxy, paint-like, crayon-like, or putty-like smell, it may be oxidized. Don’t keep pouring it into the skillet just because half the bottle remains.

When in doubt, take it back.

Why the Skillet Test Can Mislead You

You may have heard that you can prove avocado oil is fake by heating it until it smokes. Unfortunately, that home test isn’t dependable.

A smoke point depends on the oil’s level of refinement, age, free-fatty-acid content, storage history, impurities, and the accuracy of the pan temperature. Refined avocado oil is often advertised with a smoke point near 500°F, while virgin oils may begin smoking at lower temperatures.

Therefore, an oil smoking at 400°F doesn’t prove it contains soybean or canola oil. Likewise, an oil that stays quiet at high heat isn’t automatically genuine.

More importantly, deliberately overheating cooking oil can fill the kitchen with irritating fumes and create a fire hazard. It isn’t worth turning the farmhouse kitchen into a laboratory when only proper chemical analysis can reliably identify adulteration.

Use your eyes and nose to catch obvious spoilage, but don’t mistake a home test for a lab report.

Trust Is Good. Verification Is Better.

At the end of the day, most of us buy avocado oil because we’re trying to make a better choice. We pay extra because we believe the bottle contains exactly what it says—not bargain oil dressed up for Sunday meeting.

Yet the research tells a sobering story. The trouble has shown up in bottled oils, private-label products, and now processed foods proudly advertised as being made with avocado oil.

So treat every bottle the way you’d treat a stranger rattling the gate after dark.

Read the label. Check the producer. Look for independent testing. Buy a sensible size. Store it properly. And never assume that a high price, green label, or fancy health claim is proof of what’s inside.

Because when you’ve worked all season to put honest food on the table, the last thing you need is a counterfeit ingredient sneaking into the skillet.
