Considered a culinary delicacy, truffles are commonly found in high-end restaurants and Haute cuisines. There are several varieties of truffles, including black summer truffle, Australian truffle, Burgundy truffle, Chinese black truffle, Perigord truffle, white Piedmont truffle, and many more. 

If you want to sprinkle a touch of truffle oil over French fries or order pasta with truffles, you might wonder, are truffles vegan?

Truffles are fungi and are technically vegan. However, eating truffles is an ethical dilemma for some vegans because of the way these fungi are harvested. Since truffles grow underground, people use trained pigs and dogs to sniff them out. Some vegans object to this and refuse to eat truffles. 

Interested to learn more about truffles – keep reading! In this article, we’ll explain what truffles are, how they are grown, and why some vegans avoid eating them. 

What Are Truffles?

A truffle is a fruiting body of the subterranean ascomycete fungus. Truffles are considered ectomycorrhizal fungi, meaning they are found close to tree roots.

These fungi form a symbiotic relationship with tree roots, creating a network called mycelium that allows truffles and trees to exchange nutrients for mutual benefit. 

Truffles grow underground in very specific conditions. Growing truffles is exceptionally challenging, and the majority of the commercially-sold truffles have been found in nature. 

The current method of harvesting truffles involves using certain animals, mainly pigs and dogs. These animals are specially trained for truffle hunting to locate the fungi in the ground by sniffing them out. 

Truffle hunting hogs and dogs are valued for locating and unearthing truffles for their owners. Because of their important role, these animals are treated nicely and kept in excellent condition. 

Are Truffles Vegan?

Truffles are technically mushrooms, which makes them perfectly safe for vegans. Truffles don’t contain any animal or animal-derived products and aren’t processed using animal products.

Veganism is a lifestyle that excludes all animal products and strives to limit animal exploitation and cruelty as much as possible. 

When it comes to vegans, the issue isn’t with truffles, it’s with the way they forage. Common methods of finding naturally occurring truffles involve the use of trained pigs and dogs for their sense of smell. 

Because of this, many vegans believe that the way truffles are harvested excludes them from the vegan-friendly food list, even though these fungi aren’t produced or processed using animal products. 

Two factors play a significant role in truffle collection. Firstly, truffles grow underground, which makes them difficult to find. Secondly, the right time to harvest truffles is when they are ripe. Collecting truffles too soon or too late makes them inedible.

To harvest truffles correctly, people use hogs and dogs, whose keen senses of smell allow them to distinguish distinctive aromas of ripe truffles. 

Throughout history, pigs have been the standard animals used for truffle harvesting. However, modern truffle hunters started relying more on dogs to locate truffles. 

The primary issue with using hogs is that although they possess a superior sense of smell, they can accidentally eat the truffle until the handler arrives at the location. On the other hand, dogs haven’t shown any interest in eating truffles and are less likely to cause any damage.

Why Do some Vegan-Diet People Avoid Truffles?

Many vegans don’t believe that truffles are vegan because of the use of animals when harvesting truffles. For many vegans, the actual truffle is vegan, but the process of collecting it isn’t.

PETA wrote an article that sheds light on dog breeding and explains why people shouldn’t support dog breeders. Unfortunately, many breeders treat dogs as commodities and use them to earn a quick buck. 

Some dog breeds are better at sniffing out objects than others, which may cause unethical breeders to force dogs to reproduce repeatedly to increase their profits.

No one is saying this is a standard practice among those who breed truffle hunting dogs. However, dog breeding isn’t vegan because dogs are treated as commodities and are deemed unethical by dietary vegans. 

Can Vegans Eat Truffle Oil?

Truffle oil is made using oil and truffles. Although truffle oil is technically vegan, many vegans refuse to consume it because animals were used to harvest truffles. 

Traditional truffle oil infuses the necessary aromatic compounds from truffles into various oils. Olive oil is used most commonly, but grapeseed oil and canola oil are used as well to make truffle oil. 

Many modern truffle oils have been found to be mostly synthetic. Synthetic compounds, similar to those found in truffles, are simply added to the oil. 

These synthetic compounds aren’t as complex or flavorful as real truffles. But the good news for vegans is that these synthetic oils are vegan-friendly and safe to consume. 

Please note that some manufacturers use fish oil and dairy products to dilute their truffle oil. Always check the label and the ingredient list to ensure the product is made and processed without animal products.

This is the best way to ensure the truffle oil you want to purchase is actually vegan.


Called the diamond of the kitchen, the delicious truffles are cherished by many but are a subject of much controversy in the vegan community. Truffles are subterranean fungi and one of many species in the genus Tuber.

These expensive fungi grow in the ground, near tree roots, and are the result of the symbiotic relationship between the tree and the fungi. As fungi, truffles are technically vegan.

However, the process of harvesting naturally occurring truffles involves the use of pigs or dogs for their superior sense of smell. The fact that animals are used in finding and collecting truffles may make some vegans reluctant to eat them. 

Truffles don’t contain animal products or any ingredients derived from animals. But ultimately, it is up to every vegan to decide whether or not to eat truffles.
