Eating Raw Mushroom | Risks and Safety Measures

Have you ever studied about the toxins that are present in mushrooms?  I have heard some famous doctors say some mushrooms are very toxic for health as they have toxins that may cause several health issues.

But raw mushrooms are generally safe to eat, they might not be as easily digestible as cooked mushrooms. Ensure you correctly identify mushrooms, especially wild varieties, before eating raw mushrooms.

In this article, we will discuss the safety of eating raw mushrooms, exceptions where it may not be safe, and explore which mushrooms are suitable for raw consumption and which are not. Additionally, we will examine whether mushrooms are healthier to eat raw or cooked.

Eating Raw Mushroom

What Are Edible Or Raw Mushrooms?

The oyster mushroom (Pleurotus ostreatus) is widely regarded as one of the healthiest edible mushrooms available. For centuries, it has been celebrated not only for its delectable taste but also for its exceptional nutritional value. Rich in essential vitamins and minerals like vitamin D, iron, magnesium, phosphorus, and zinc, oyster mushrooms offer a range of health benefits.

One of the notable components found in oyster mushrooms is polysaccharides, which possess valuable antioxidant and anti-inflammatory properties. These compounds contribute to overall well-being and support the body’s defense mechanisms.

Moreover, oyster mushrooms contain chitin, a potent prebiotic pivotal in reducing inflammation, enhancing gut health, and fortifying the immune system. Including chitin in the diet can promote better digestive health and boost immunity.

Is Eating Raw Mushroom Safe?

Raw mushroom ( button, oyster, and shiitake) consumption is safe for most people, and they can be included in salads or veggie trays at parties. However, some individuals might experience mild digestive discomfort after eating raw mushrooms.

The reason behind this comfort is their rigid cell walls, which can be broken down through cooking. Cooking mushrooms makes their nutritional content more accessible for our bodies to absorb.

Eating Store Bought Mushroom Raw

While it is technically possible to consume raw store-bought mushrooms, it is generally not advised for a few important reasons. Mushrooms contain natural compounds that can be difficult for our bodies to digest in their raw state.

Cooking mushrooms helps break down these compounds, making them more easily digestible and potentially reducing digestive discomfort. Moreover, certain varieties of mushrooms can be toxic when consumed raw, posing a health risk. Therefore, cooking mushrooms before incorporating them into your meals is always safer.

Beyond the safety aspect, cooking mushrooms offers several culinary benefits. When exposed to heat, mushrooms release their natural flavors, resulting in a more enjoyable and flavorful eating experience. Additionally, the cooking process can enhance the nutritional value of mushrooms, making their nutrients more accessible to our bodies.

Eating Slightly Raw Mushrooms

When it comes to consuming slightly raw mushrooms, the consensus is that they are not likely to pose a significant danger unless contaminated with harmful substances. However, it’s essential to be aware that some individuals might experience digestive discomfort, such as nausea, vomiting, or diarrhea, as a result.

While raw mushrooms typically do not contain harmful toxins, it’s important to note that specific mushroom varieties may trigger allergic reactions. These reactions can manifest as rashes, hives, wheezing, or anaphylaxis in severe cases.

Given these factors, it is advisable to stick to cooked mushrooms, ensuring they are thoroughly heated to eliminate any potential bacteria, toxins, or other harmful elements that might be present.

To guarantee safety, it is also recommended to purchase mushrooms from reputable sources and take the necessary precautions by cooking them adequately before consumption. Taking these steps can minimize any potential risks associated with consuming mushrooms.

What Kind of Raw Mushrooms Should Be Avoided?

Certain wild mushrooms, such as the toxic varieties, should never be consumed raw as they can be poisonous and pose serious health risks. To avoid potential dangers, correctly identifying and cooking wild mushrooms before consumption is crucial.

Can Humans Digest Raw Mushrooms?

Raw mushrooms are difficult to digest because they contain chitin in their cell walls. While human stomachs contain chitinase that can break down chitin to a limited extent, its primary function is defending against chitin-based parasites rather than entirely breaking down chitin.

As a result, consuming raw mushrooms may not provide optimal nutrition to humans since the chitin mainly remains intact, hindering essential nutrient absorption. Cooking mushrooms, on the other hand, helps break down their cell walls and releases nutritional and medicinal compounds, making them easier for humans to absorb and utilize.

In analogy, chitin in mushrooms can be likened to plant cellulose, which both add fiber to the diet. Thus, raw mushrooms can be a good choice if your primary goal is to increase fiber intake. However, cooking them is recommended to fully benefit from mushrooms’ diverse nutrients.


Are there any benefits to consuming raw mushrooms?

While cooking mushrooms helps release more nutrients and medicinal compounds, some people prefer the taste and texture of raw mushrooms. However, raw mushrooms might not provide the same level of nutrition as their cooked counterparts.

How can I minimize the risks of eating raw mushrooms?

If you choose to eat raw mushrooms, ensure they are fresh, clean, and from a reputable source. Consider slicing or marinating them to improve digestibility. However, cooking mushrooms thoroughly is recommended for maximum nutritional benefits and safety.

Are White Mushrooms Poisonous to Eat?

White mushrooms, or “button” mushrooms, are safe and non-poisonous. Moreover, the antioxidants found in white mushrooms play a significant role in protecting the body against diseases, including cancer and heart disease.

Final Thoughts

Eating raw mushrooms is generally safe.  But it may be difficult for the human digestive system to break down chitin. This may lead to gastrointestinal discomfort or hinder nutrient absorption.

So, understanding the potential health risks is crucial before including raw mushrooms in your diet. Seeking advice from a mycologist or an expert in fungi can be beneficial in distinguishing edible mushrooms from toxic ones.
