What You'll Learn
Raw mushrooms may contain parasites, bacteria, and viruses
While raw mushrooms are considered safe to eat, they may contain parasites, bacteria, and viruses. The risk of ingesting these contaminants can be significantly reduced by cooking the mushrooms. Therefore, people with compromised immune systems or specific health conditions are advised to consult a healthcare professional before consuming raw mushrooms.
Mushrooms purchased from stores are generally safer than wild mushrooms, as they are less likely to be toxic. However, it is important to follow food safety guidelines and ensure that the mushrooms are sourced from reputable suppliers who comply with safety regulations. Proper cleaning and preparation techniques are crucial to eliminate any potential bacteria or residue.
One of the primary concerns with raw mushrooms is the presence of bacteria, particularly Listeria. Listeria monocytogenes, found in Enoki mushrooms, caused a foodborne outbreak with serious consequences, including hospitalizations and deaths. Other types of bacteria, such as Staphylococcus, can also contaminate mushrooms, especially if they are extensively handled before canning and stored at ambient temperatures.
The conditions in which mushrooms are packaged and stored can contribute to the growth of harmful bacteria. For example, storing fresh mushrooms in an airtight container without refrigeration may promote the growth of bacteria that cause botulism. Therefore, it is recommended to refrigerate mushrooms in their original packaging or a paper bag to prevent the risk of food poisoning.
To minimize the risk of bacterial contamination, it is essential to clean mushrooms thoroughly before consumption. Washing them under cold running water or using a soft brush can help remove any soil or residue. Additionally, blanching, a quick submersion in boiling water, can effectively reduce surface bacteria while preserving the raw texture and flavor.

Cooking mushrooms can increase their nutritional value
Mushrooms are a nutritious food with many health benefits. They are low in calories and fat, and they contain moderate amounts of protein, making them a good source of plant-based protein. They are also a good source of fibre, vitamins, and minerals, such as potassium, riboflavin, niacin, and vitamin D. Some varieties of mushrooms, such as lion's mane, are also rich in antioxidants, polysaccharides, and beta-glucans, which have immune-boosting and brain-boosting properties.
While some edible mushrooms can be consumed raw, cooking them can increase their nutritional value and make them safer to eat. Raw mushrooms may carry harmful parasites, bacteria, and viruses, which can cause food poisoning or digestive issues, especially in individuals with weakened immune systems, such as pregnant people. Cooking mushrooms can reduce the risk of ingesting these contaminants and make them easier to digest.
Some mushrooms, such as morels and chanterelles, contain toxins that can cause serious health issues, including gastrointestinal distress and neurological symptoms. Cooking these mushrooms is essential to breaking down the toxins and making them safe to eat. Additionally, cooking mushrooms can enhance their flavour and make them more palatable. For example, cooking morels enhances their nutty flavour, and cooking lion's mane softens its fibres, making it easier to digest.
The way mushrooms are cooked can also impact their nutritional value. Boiling mushrooms is not recommended as it can lead to nutrient loss and a soggy texture. Deep-frying mushrooms is also not a healthy option due to the high level of saturated fats in frying oils. Lightly cooking mushrooms, such as through sautéing or grilling, can be a better option to preserve their nutrients and improve their digestibility.
Overall, while some mushrooms can be consumed raw, cooking them is generally recommended to increase their nutritional value, improve their flavour and texture, and reduce the risk of foodborne illnesses. However, it is important to follow food safety guidelines and proper cooking techniques to maximize the health benefits of mushrooms.

Some mushrooms are unsafe to eat raw, e.g. morels and honey mushrooms
Mushrooms are highly nutritious and considered a superfood. They are high in selenium, vitamin D, and vitamin B6, and assist in immune health, digestion, heart health, and brain health. They are also low in calories and fat. However, it is preferable to cook mushrooms rather than eat them raw. Cooking mushrooms can reduce the risk of ingesting parasites, bacteria, and viruses. This is especially important for individuals with compromised immune systems, as well as for pregnant women, as raw mushrooms may contain bacteria such as Listeria.
Some mushrooms are unsafe to eat raw, including morels and honey mushrooms. Morel mushrooms, for instance, have been linked to severe food poisoning outbreaks, with the FDA finding that undercooked or raw morels were the likely cause. The toxins in morel mushrooms are not fully understood, but cooking helps to reduce toxin levels. "False" morels, which resemble edible morels, are toxic whether raw or cooked.
Honey mushrooms are edible and considered a delicacy in many parts of the world, but they must be cooked before consumption as they are poisonous when raw. They are also slimy and fibrous, which makes them less appealing to eat on their own. Honey mushrooms have a unique appearance, growing in tight clusters with stems ranging in color from white to yellowish-brown, and they have a slightly acidic odor. They are a good source of antioxidants and have been shown to have cancer-fighting and blood sugar-lowering properties.
It is important to correctly identify mushrooms before consuming them, as many mushrooms look alike, and some varieties are poisonous. When foraging, it is best to stick to well-known, safe-to-consume mushroom species. Mushrooms purchased from grocery stores are generally safer than wild species, as they are assumed to be safe for consumption.
