Back in 2002, McDonaldโs settled a lawsuit with Hindus and vegans and agreed to pay $10 million in a class action suit brought over its use of beef tallow in McDonaldโs fries. The suit complained that McDonaldโs used beef tallow in the fries without letting customers know while claiming they were fried in vegetable oil. The result? McDonaldโs fries are not as good as they used to be and are not actually more healthy. But, the public is still confused about whether McDonaldโs continues to use beef in their French fries, because of the way the ingredients are listed. Do McDonaldโs French Fries contain beef? The answer is we donโt know.

As a result of the lawsuit, McDonald’s issued an apology to โHindus, vegetarians, and others for failing to provide the kind of information they needed to make informed dietary decisions at our U.S. restaurants.โ
Even before settling the lawsuit, McDonaldโs began bowing to public pressure, removing beef tallow from its French frying oil in the 1990s and using 100% vegetable oils. After the public complained about the dreary results, McDonaldโs changed the recipe again. There is no beef tallow, but this does not mean there is now no beef in McDonaldโs French Fries. Here is the ingredient listing for McDonaldโs Fries:
Potatoes, Vegetable Oil (canola Oil, Corn Oil, Soybean Oil, Hydrogenated Soybean Oil, Natural Beef Flavor [wheat And Milk Derivatives]*), Dextrose, Sodium Acid Pyrophosphate (maintain Color), Salt. *natural Beef Flavor Contains Hydrolyzed Wheat And Hydrolyzed Milk As Starting Ingredients.
The ingredients clearly state โnatural beef flavoring.โ The confusion comes from the inclusion of โwheat and Milk Derivativesโ in brackets and then at the end of the listing โNatural beef Flavor Contains Hydrolyzed Wheat And Hydrolyzed Milk as Starting Ingredients.โ
It may be a benefit to the company that this confuses the public about whether or not there is beef in the fries, but it is actually there due to updated FDA rules regarding ingredient listings for natural flavors. As well, the listing must disclose wheat and milk ingredients as an allergen warning for those with a wheat or milk allergy, as well as celiac sufferers.
The beef flavoring isnโt inside the fries. They are just cut potatoes. But, McDonaldโs explains that when their suppliers partially fry the potatoes, they use an oil blend that contains beef flavoring.
So, does this โbeef flavoringโ use beef? Itโs quite possible that it does not. Most โmeatโ flavorings are made from hydrolyzed amino acids, sugars, citric acid, and other additives. A food chemist named Gary Reineccius explained it to Eater in 2015:
โฆthe flavor in beef is created during the cooking process. Food scientists identified the amino acids found in beef, added some very common sugars โ starch hydrolysate โ put it in a pot, added some citric acid to drop the pH, controlled moisture content, and heated it to the same temperature as meat. Thenโฆ*poof* we have meat flavor
McDonaldโs and other companies are not required to disclose what exactly is used in a โflavor additiveโ as long as all the ingredients are GRAS or โgenerally recognized as safe.โ This is subject to the updated rules I mentioned above, and the need to provide allergen warnings. Meat ingredients are not included in allergen warnings.
Beef is an expensive ingredient to use only to add flavor, so chances are there is not any meat in the beef flavor used by McDonaldโs. Using the processes described, an unami-like flavor similar to beef can be achieved without using any beef at all. No matter the process used, the term โnatural flavorโ can be used on the ingredient listing. Here is how it is defined by the FDA:
The term natural flavor or natural flavoring means the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating or enzymolysis, which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof, whose significant function in food is flavoring rather than nutritional.
However, the updated 2019 rules for natural flavoring state that hydrolyzed animal vegetable protein cannot be identified solely as โnatural flavoringโ on the label:
FSIS regulation requires that animal or vegetable proteins must be specifically identified in the ingredient statement on the labels. The source of the protein must also be disclosed. On the label, you will read โhydrolyzed wheat proteinโ or โhydrolyzed milk protein,โ not just hydrolyzed protein.
This explains why McDonaldโs lists Hydrolyzed Wheat and Milk in the ingredients for its French fries in addition to a milk and wheat allergen warning below the listing.
These rules also included things like โbeef brothโ or โmeat extract.โ
Can the terms โdried meat or poultry stocks,โ โdried broth,โ โmeat extracts,โ and โdried beef plasmaโ be listed on meat and poultry labels as โnatural flavoringsโ?
No. Substances derived from animal sources must be identified as to the species of origin on the label and be consistent with the definition established by Federal regulation. For example, the listing on the label would read โdried chicken stock,โ โlamb extract,โ or โdried beef plasma.โ
This means that sometimes companies need to list when meat ingredients are used in their natural flavor and sometimes they do not. While we know that the beef flavoring contains wheat and milk ingredients, we have no way of knowing, for sure, whether it contains beef. McDonaldโs is keeping this information close to its chest.
Why? If beef caused such a controversy and the fries do not use beef ingredients, why not proudly state as much? Well, not everyone, including myself, was thrilled with the decision to stop using beef tallow in the cooking oil. Many restaurants with great-tasting fries put some beef fat into their cooking oil mix. It tastes good. While Iโm only speculating, I suspect that playing both sides is what the company wants. The company is not claiming its fries are vegan since they admit they contain milk.
On the other hand, McDonaldโs UK clearly states that its fries are vegan!
Pentland Dell and Shepody potatoes, which are chosen for their quality, taste and long shape when cut. The fries are not coated in any fats or substances from an animal. Once at the restaurant, our fries are simply cooked in dedicated frying vats in a non-hydrogenated blend of sunflower and rapeseed oil which is 100 percent suitable for vegans.
But McDonaldโs US doesnโt have to say its fries are suitable for vegans as they are not. So, they donโt have to clearly state whether they are โcoated in any fats or substances from an animal.โ
