What You'll Learn
- Mycotoxins can be absorbed through the skin, but it's unlikely to be fatal
- Poisonous mushrooms can look and taste the same as edible ones
- Amatoxins can cause liver failure and death
- Some mushrooms can cause severe inflammation and irritation upon contact
- Poisoning symptoms can take several hours to days to appear
Mycotoxins can be absorbed through the skin, but it's unlikely to be fatal
While it is true that some mycotoxins can be absorbed through the skin, it would take a massive amount of exposure to lead to a fatal reaction. For example, a lethal dose of amatoxin, a toxic compound found in the highly poisonous "death cap" mushroom, is 0.1 mg/kg or 7 mg total for an adult. A single death cap mushroom may contain up to 12 mg of amatoxin, but simply handling it, even for an hour, is unlikely to cause harm. As a comparison, one source estimates that you would need to handle hundreds of pounds of poisonous mushrooms per day to experience a fatal reaction.
This is not to say that poisonous mushrooms are not dangerous. Consuming even a small bite of a poisonous mushroom can be harmful and even life-threatening. The symptoms of mushroom poisoning can vary from gastrointestinal discomfort to liver and kidney failure, and in some cases, massive bleeding can lead to death. However, touching mushrooms, even the most poisonous varieties, is generally not harmful in and of itself.
It is important to note that it can be difficult to distinguish between poisonous and edible mushrooms, and they often do not look or taste any different. Therefore, it is recommended to exercise caution when foraging for mushrooms and to avoid touching them with bare hands to prevent any chance of contaminating edible mushrooms. If you suspect that you or someone you know has eaten a poisonous mushroom, it is crucial to seek medical help immediately.
In summary, while it is true that some mycotoxins can be absorbed through the skin, it is unlikely to be fatal unless an extremely large quantity of poisonous mushrooms is handled. The primary danger of poisonous mushrooms lies in consuming them, and even a small amount of ingestion can lead to serious health consequences. Therefore, it is important to be able to identify different mushroom species accurately and to seek medical assistance in the event of suspected mushroom poisoning.

Poisonous mushrooms can look and taste the same as edible ones
While touching mushrooms is not dangerous, consuming unidentified mushrooms can be harmful and even fatal. Poisonous mushrooms can look and taste similar to edible mushrooms, making it difficult to distinguish between the two.
Mushroom poisoning is a serious issue, with symptoms ranging from mild nausea and vomiting to seizures and liver failure. It is important to seek emergency medical care if you or someone you know ingests an unidentified mushroom, even if there are no apparent symptoms.
Identifying poisonous mushrooms can be challenging, even for experts. Many toxic mushrooms resemble edible varieties in appearance and taste. For example, the Destroying Angel, a highly poisonous mushroom, has a similar appearance to the edible Shaggy Mane mushroom. Similarly, the deadly poisonous Death Cap mushroom is reported to have a pleasant taste.
Taste testing mushrooms is not a reliable method for determining their edibility. While it is true that some mushrooms, such as those in the Russula family, have distinctive tastes that indicate their toxicity, this is not the case for all species. Relying solely on taste can be dangerous, as some poisonous mushrooms may taste mellow or pleasant but still contain harmful toxins.
To stay safe, it is crucial to properly identify mushrooms before consuming them. Amateur foragers should exercise caution and seek guidance from experts or reliable sources to avoid accidental poisoning.

Amatoxins can cause liver failure and death
While touching mushrooms is generally not dangerous, consuming them can be harmful. Amatoxins, toxic compounds found in certain mushrooms, can cause liver failure and even death. Amatoxin poisoning is a rare but significant cause of acute fulminant liver failure. It is produced by the Amanita phalloides mushroom, also known as the "death cap" mushroom, which is responsible for the majority of mushroom toxicity cases in humans.
Amatoxins interfere with protein synthesis by inhibiting RNA polymerase, disrupting DNA and RNA transcription, and causing cell death. This results in a progressive decrease in mRNA and deficient protein synthesis, leading to liver failure and, in some cases, death. The symptoms of amatoxin poisoning can range from severe gastrointestinal distress, such as stomach cramps, vomiting, and diarrhea, to more serious complications like irreversible liver and kidney failure.
The danger of amatoxin poisoning lies in the delay of symptoms, which can take 6 to 24 hours or even longer to appear. By the time symptoms manifest, the toxins have already been completely absorbed into the body. After an initial phase of digestive symptoms, there may be a period of apparent recovery lasting a few days before a relapse occurs. This delay can be deceptive and lead to a worsening of the condition.
While amatoxin poisoning can be life-threatening, death is rare if treatment is started immediately. Early access to intensive care and timely intervention can significantly improve outcomes. However, it is important to note that there is no known antidote for amatoxin poisoning, and the prognosis depends on the type of mushroom ingested and the time taken to seek medical care.
It is crucial to exercise caution when foraging or consuming wild mushrooms. Proper identification of edible and non-edible mushrooms is essential to prevent accidental poisoning. While touching mushrooms is not generally a cause for concern, consuming unidentified mushrooms can have severe and potentially fatal consequences.

Some mushrooms can cause severe inflammation and irritation upon contact
While most mushrooms are not dangerous to touch, some varieties can cause severe inflammation and irritation upon contact. For instance, Podostroma cornu-damai contains trichothecene toxins that can be readily absorbed through the skin, leading to rapid and severe inflammation. Amatoxins, another type of mycotoxin, can also be absorbed through the skin, but the amount of exposure from touching would not typically be enough to cause harm. However, it is crucial to exercise caution when handling wild mushrooms, especially if you plan to consume them.
Mushroom poisoning can have severe consequences, including gastrointestinal discomfort, liver failure, and even death. The most common dangerous mushrooms belong to the Amanita genus, specifically Amanita phalloides, also known as "'death cap' mushrooms. These mushrooms contain amatoxins, which are toxic compounds that damage liver cells. Symptoms of Amanita poisoning may not appear until 6 to 24 hours after ingestion, and the initial phase of digestive symptoms may be followed by a temporary recovery period before a relapse occurs.
It is essential to properly identify mushrooms before consuming them. Many poisonous mushrooms have a similar appearance to edible varieties, making it challenging for foragers to distinguish between safe and toxic fungi accurately. While touching poisonous mushrooms is usually not harmful, it is advisable to avoid direct contact with bare hands when foraging to prevent any possible contamination of edible mushrooms.
While mushroom poisoning can be life-threatening, it is important to remember that only about 3% of known mushroom varieties are poisonous. With proper identification and caution, the risks associated with touching or consuming mushrooms can be mitigated. However, if you suspect that you or someone you know has ingested a poisonous mushroom, it is crucial to seek immediate medical assistance.

Poisoning symptoms can take several hours to days to appear
While touching mushrooms is generally safe, consuming them can be harmful. Poisoning symptoms can vary from gastrointestinal discomfort to liver failure and death, depending on the type of toxin ingested.
The symptoms of mushroom poisoning can appear within a few minutes to several hours or even days after ingestion. For example, in the case of Amanita poisoning, initial symptoms usually begin six to 24 hours after ingestion but can be delayed and show up even later. This delay is deceptive because, by this time, the toxins in the mushrooms have been completely absorbed. After an initial phase of digestive symptoms, there may be a period of apparent recovery lasting two to three days, followed by a relapse and possible liver and kidney failure.
The onset of symptoms can also depend on the type of mushroom. For instance, poisoning by Orellanine typically has a slower onset, with symptoms appearing 24 hours to 21 days after ingestion. In contrast, poisoning by Amatoxins or Allenic Norleucine can have a faster onset, with symptoms appearing within six to 11 hours.
It is worth noting that mushroom poisoning is challenging to diagnose, and doctors rely on information provided by the patient, including the time of ingestion and a sample of the mushroom, if possible. Therefore, if you suspect mushroom poisoning, it is crucial to seek medical attention promptly and provide as much information as possible to ensure timely and appropriate treatment.
