Enjoyed by many around the world, mushrooms tend to be a polarizing food that diners either love or hate. However, those who enjoy noshing on the fungi must be careful about which mushrooms they ingest, as about 30 wild species are known to be consistently fatal due to high levels of toxicity, and at least 40 others have been proven to cause severe allergic reaction and occasional death.

Mushroom poisoning, or mycetism, occurs in about 6, to 7, cases per year in the United States alone. Many of the most lethal mushrooms do not appear to be threatening, and in fact several look similar to their edible cousins.

These are eight of the most poisonous species of mushrooms in the world, which should be avoided at all costs. This mushroom may be familiar, because it looks like the iconic toadstool found in most fairytales and children's stories, with its bright red cap adorned with white spots. The fly agaric is poisonous for humans due to muscimol and ibotenic acid, which act on the central nervous system and cause a loss of co-ordination, a mix of agitation followed by sleep, intense nausea, and sometimes hallucinations.

Toxic effects of the mushroom display about one hour after ingestion. Despite its host of symptoms, the fly agaric is rarely lethal for humans but poses a high degree of risk because of sporadic behavior caused by intoxication. However, the same toadstools, when consumed by household pets like cats or dogs who find them in the wild, are fatal. The name of this gilled mushroom speaks for itself. Accidentally eating the mushroom causes severe liver toxicity and if not treated immediately can be fatal.

Initial symptoms of amatoxin poisoning are largely gastro-intestinal but death may take some time as it comes as a result of liver failure. The red fruiting bodies of this rare mushroom contain trichothecene mycotoxins, which can cause multiple organ failure. Podostroma cornu-damae are native to Asia and have been responsible for many deaths in Japan and Korea.

Symptoms include stomach pain, peeling skin, hair loss, low blood pressure, liver necrosis, and kidney failure. If untreated, poisoning can be fatal within a matter of days.

Podostroma cornu-damae are typically consumed in error because they look similar to the edible ganoderma lucidum variety. The destroying angel is the most common toxic mushroom worldwide, containing high levels of amatoxins that cause fatal mycetism.

In keeping with its name, the fungus begins destroying liver and kidney tissue within two or three hours of consumption, and sufferers experience violent cramping and diarrhea, delirium, convulsions, and vomiting before succumbing to kidney and liver failure. These all-white, oval-shaped mushrooms are often called the fool's mushroom because they imitate edible species.

The autumn skullcap, about and inch and a half in width, tends to grow on decaying coniferous trees and is yellow-brown to brown in color. It is sometimes confused with edible varietals like honey fungus, sheathed woodtuft, and velvet foot. These mushrooms are found throughout the world, including northern points like the Arctic and southern regions such as Australia.

Like many toxic species of mushroom, the skullcap contains amatoxin and can result in death within seven days due to liver failure after suffering from diarrhea, vomiting, and hypothermia. Webcaps are typically a rusty brown-orange color and are commonly found in northern Europe and parts of North America, particularly in subalpine forests.

Their toxicity is a result of extremely potent orellanin and symptoms are initially flu-like and can take anywhere from two days to three weeks to surface, but lead to kidney or liver failure and, often, death.Cucurbits are a gourd family of flowering plants that include cucumbersmelons, squash and pumpkinswhich can be delicious, healthful foods to enjoy in your diet.

Squash can contain a toxic compound called cucurbitacin E. A March report published in the Journal of the American Medical Association tells of two French women who became quite ill and experienced massive hair loss following unrelated cases of cucurbit poisoning. Although it can be quite serious, cucurbit poisoning is also very rare. Learning how it occurs, how to avoid it and what to do if you should ever contract toxic squash syndrome can help you protect yourself and your family.

Getty Images Mario Tama. Plants in the Cucurbitaceae family produce the toxin cucurbitacin as a natural defense against insects. Cross-pollination with wild plants as well as some type of stress during growth, such as lack of adequate water or poor fertilization, are some of the factors believed to cause increased cucurbitacin in squash and other produce.

Since cross-pollination is a contributing factor to large concentrations of cucurbitacin, do not eat squash that you are unfamiliar with, either. Flickr mrsdewinter. If you have eaten even just a few bites of exceedingly bitter squash, pumpkin, cucumber or another member of the cucurbit family, watch for these symptoms:. In addition, substantial hair loss can occur several weeks after curcurbitacin poisoning.

The two women noted in the JAMA report experienced hair loss from their scalps and bodies that took several months to regrow. However, researches stated that these are the first known cases of hair loss caused by cucurbit poisoning. Pixabay derneuemann. In most cases, cucurbit poisoning will run its unpleasant course much like other instances of food poisoning.

However, in a German man died and his wife was hospitalized after eating a significant amount of toxic zucchini in a stew. Seek medical attention if you become dehydrated, have excessive pain or dizziness, experience ongoing stomach issues or believe you have consumed more than a bite or two of food containing high amounts of cucurbitacin.

Jaundice is yellowing of the skin and eyes, which is why this disease is called yellow fever. This disease is most prevalent in certain parts of Africa and South America.

Yellow fever develops quickly, with symptoms occurring three to six days after exposure. The initial symptoms of the infection are similar to those of the influenza virus. They include:. After the acute phase is over, symptoms will begin to go away. Many people recover from yellow fever at this stage, but some people will develop a more serious version of this condition.

The symptoms that you experienced in the acute phase may disappear for up to 24 hours. Then, those symptoms will return, along with new and more serious symptoms. These include:. This phase of the disease is often fatal, but only 15 percent of people with yellow fever enter this phase.

Mosquitoes become infected with the virus when they bite an infected human or monkey. The disease cannot be spread from one person to another.

Mosquitoes breed in tropical rainforests, humid, and semi-humid environments, as well as around bodies of still water. According to the World Health Organizationan estimatedpeople become infected each year.

Most cases occur in 32 countries in Africa, including Rwanda and Sierra Leone, and in 13 countries in Latin America, including:. Your blood sample will be analyzed for the presence of the virus or for the antibodies meant to fight the virus. Treatment involves managing symptoms and assisting your immune system in fighting off the infection by:. The WHO estimates that 50 percent of people who develop severe symptoms of this condition will die. Older adults and those with compromised immune systems are most at risk for serious complications.

The yellow staining mushroom Agaricus xanthodermus is the most commonly eaten poisonous mushroom in Victoria. This species commonly grows wild in lawns and gardens, and looks very similar to edible mushrooms.

In Victoria, most poisonous fungi are eaten during autumn. The most commonly eaten poisonous mushroom in Victoria is the yellow staining mushroom Agaricus xanthodermusbecause it looks very similar to the field mushroom Agaricus campestris and the cultivated mushroom Agaricus bisporus.

Unfortunately, some of these plants are toxic to livestock. Signs of toxicity can range from as mild as brief indigestion to as severe as sudden death. The plants discussed here were selected because of their ability to cause serious illness, abundance in the PNW or other special factors. To learn about other potential sources of plant toxicity, producers are encouraged to consult the references cited at the end of this article.

Wild cherry, chokecherry, black cherry, peach, apricot and cherry laurel Prunus species have poisonous leaves, twigs and bark. The toxic agent is a cyanogenic glycoside which makes hemoglobin unable to release oxygen at the tissue level.

Signs of poisoning appear rapidly and are those of cyanide toxicity: difficulty breathing, excitement, tremors, gasping, dilated pupils, bright pink mucous membranes, bloat, staggering, involuntary urination and defecation, convulsions, coma and death due to asphyxiation.

Blood and mucous membranes of affected animals are bright red. Livestock ingest Prunus plant material when other forage is unavailable and out of curiosity when a branch falls into a pasture. Fruit from Prunus species is not poisonous but seeds and pits are. Treatment includes sodium nitrite and sodium thiosulfate; many cases die too quickly to receive treatment. During autopsy, an odor of bitter almonds can sometimes be detected in the rumen. Japanese Yew Taxus cuspidata is a common ornamental shrub that is extremely toxic due to the presence of taxine, ephedrine and cyanide alkaloids.

Leaves, twigs and seeds are toxic.

Livestock can ingest this plant if they gain access to landscaped lawns or if homeowners trim yew shrubs and give the trimmings to livestock. Signs of poisoning include vomiting, diarrhea, bloat, weakness, nervousness, trembling, difficulty breathing, incoordination, dilated pupils, decreased heart rate, convulsions, coma and death due to cardiac standstill. Treatment with atropine may be somewhat helpful but most cases are fatal.

On autopsy, yew plant parts can be identified in stomach or rumen contents. Prunus species: note smooth, shiny bark with horizontal lines. Photo courtesy Cornell University. Wild black cherry: note shiny elliptical leaves, berries in clusters. Photo courtesy Purdue University. Choke cherry: note glossy leaves, berries in clusters. Photo courtesy University of Pennsylvania. Red berry with seed in center. Yew: note glossy, flat, needle-like leaves.

Oleander: note narrow evergreen leaves; shrub can be very large. Oleander Nerium oleander is another extremely toxic ornamental shrub. All fresh or dry parts of the plant are toxic. Signs of poisoning appear quickly and include severe vomiting and diarrhea, swollen and inflamed oral tissues, cold extremities, dilated pupils, increased heart rate, weakness and death.

Food that has touched an oleander should be considered toxic, as should smoke made from a fire fueled with oleander. Treatment with atropine and propranolol may lessen cardiac effects somewhat but most cases are usually fatal.

Deathcamus Zigadenus venenosus and other species is the broad name given to a genus of at least four species of native perennial herbs that are found throughout the West. This toxic plant can cause human poisoning if its bulbs are confused with onions or camas Camassia quamash. Toxicity is due to zygacine, a steroidal alkaloid. Deathcamus is of particular concern in the early spring because it is one of the first green plants to emerge and will therefore be attractive to grazing livestock, especially sheep.

All parts of the plant are toxic, particularly the bulbs; all species of livestock can be affected. Signs of poisoning include incoordination, staggering, rapid pulse and respiration, excessive salivation, frothing from the mouth, vomiting, coma and death due to heart failure.Yellow fever is a viral infection spread by a particular type of mosquito.

The infection is most common in areas of Africa and South America, affecting travelers to and residents of those areas. In mild cases, yellow fever causes a fever, headache, nausea and vomiting. But yellow fever can become more serious, causing heart, liver and kidney problems along with bleeding. There's no specific treatment for yellow fever.

Why Isn’t The FDA Concerned?

But getting a yellow fever vaccine before traveling to an area in which the virus is known to exist can protect you from the disease. During the first three to six days after you've developed yellow fever β€” the incubation period β€” you won't experience any signs or symptoms. After this, the infection enters an acute phase and then, in some cases, a toxic phase that can be life-threatening.

Although signs and symptoms may disappear for a day or two following the acute phase, some people with acute yellow fever then enter a toxic phase. During the toxic phase, acute signs and symptoms return and more-severe and life-threatening ones also appear. These can include:. Yellow fever is caused by a virus that is spread by the Aedes aegypti mosquito. These mosquitoes thrive in and near human habitations where they breed in even the cleanest water. Most cases of yellow fever occur in sub-Saharan Africa and tropical South America.

Humans and monkeys are most commonly infected with the yellow fever virus. Mosquitoes transmit the virus back and forth between monkeys, humans or both. When a mosquito bites a human or a monkey infected with yellow fever, the virus enters the mosquito's bloodstream and circulates before settling in the salivary glands. When the infected mosquito bites another monkey or human, the virus then enters the host's bloodstream, where it may cause illness.

You may be at risk of the disease if you travel to an area where mosquitoes continue to carry the yellow fever virus. These areas include sub-Saharan Africa and tropical South America. Even if there aren't current reports of infected humans in these areas, it doesn't mean you're risk-free. It's possible that local populations have been vaccinated and are protected from the disease, or that cases of yellow fever just haven't been detected and officially reported.

If you're planning on traveling to these areas, you can protect yourself by getting a yellow fever vaccine at least several weeks before traveling. Anyone can be infected with the yellow fever virus, but older adults are at greater risk of getting seriously ill. Complications during the toxic phase of a yellow fever infection include kidney and liver failure, jaundice, delirium, and coma.

People who survive the infection recover gradually over a period of several weeks to months, usually without significant organ damage. During this time a person may experience fatigue and jaundice. Other complications include secondary bacterial infections, such as pneumonia or blood infections. A highly effective vaccine exists to prevent yellow fever.

Yellow fever is known to be present in sub-Saharan Africa and parts of South America. If you live in one of these areas, talk to your doctor about whether you need the yellow fever vaccine. If you plan to travel in these areas, talk with your doctor at least 10 days, but preferably three to four weeks, before your trip begins. Some countries require travelers to present a valid certificate of immunization upon entry. A single dose of the yellow fever vaccine provides protection for at least 10 years.
