Mushroom Toxicity

MUSHROOM TOXICITY

CAUSES:

  • Mushroom toxicity is caused by the ingestion of toxic compounds, found in certain mushrooms. The toxic agents can be Amanitin (causes severe liver and kidney damage), Muscarine (affects the nervous system, and Orellanine (causes kidney damage).

  • Inexperienced foragers may confound edible mushrooms with their look-alike toxic mushrooms.

  • The preparation of mushrooms also affects its toxicity as some mushrooms can be toxic while raw and edible when cooked.

  • Some people can be susceptible to mushrooms.

  • Environmental factors like heavy metals or pesticides can contaminate even the edible mushrooms/ can make the edible mushrooms potentially harmful.


SYMPTOMS:

Here are some common symptoms associated with mushroom poisoning:

  • Some gastrointestinal symptoms include Nausea and vomiting, Diarrhea, Abdominal pain, and cramps.

  • Neurological symptoms may include dizziness, confusion or disorientation, hallucinations, muscle twitching, or spasms.

  • Liver and kidney damage

  • Rapid heartbeat, low blood pressure

  • Difficulty in breathing, chest tightness

PATHOGENESIS

Ingestion: After ingesting a toxic mushroom, toxins enter the gastrointestinal tract.

Absorption: Toxic compounds enter the bloodstream by being absorbed through the intestinal wall. How quickly and how much of these toxins are absorbed can change based on the toxin type and the person's body.

Distribution: After entering the bloodstream, toxins spread throughout the body and target certain organs. For instance, Amanitin mainly impacts the liver and kidneys, while Muscarine targets the nervous system.

Mechanism of Action: Toxins can cause cellular damage by disrupting functions. For example, Amanitin stops RNA polymerase II, reducing protein synthesis and causing liver cell death. Orellanine creates oxidative stress, harming kidney cells. Neurotoxins like muscarine affect neurotransmitter receptors, which can lead to confusion, hallucinations, and issues with the autonomic nervous system.

Immune Response: Sometimes, the body may respond to toxins by activating the immune system, resulting in inflammation and potentially causing more harm.

Resolution or Complications: The result varies based on the type of mushroom, the quantity consumed, the timing of treatment, and a person's sensitivity. In serious cases, this can result in organ failure, necessitating medical treatment.

CONTROL

Mushroom toxicity can be controlled by the following key strategies:

  • Educating foragers on the difference between edible and wild mushrooms to reduce the risk of misidentification.

  • By spreading awareness to the public about the risks of wild mushrooms and its symptoms.

  • Regulating mushroom harvesting in public areas can help protect wild populations, while certification programs for harvesters can promote safe practices and proper identification.

  • Educating people on safe cooking methods for potentially toxic but edible mushrooms is important. Additionally, it's advisable to encourage the consumption of mushrooms from trusted sources rather than foraging for wild ones.

  • Setting up protocols for healthcare providers to quickly identify and treat mushroom poisoning is essential. Additionally, it's important to keep poison control centers informed with the latest information on mushroom toxins and their treatment options.

FST Lab 7 (Determination of Ash Content using the Gravimetric Method)

By -Published on
  Lab-7 OBJECTIVE:  To determine the ash content in a food sample using the gravimetric method.  MATERIALS Muffle furnace Crucible with a lid or china dish  Analytical balance  Sample  THEORY  Ash content is the amount of inorganic material in a food sample that remains after it has been incinerated or burned at high temperatures. It measures the total mineral content of a food sample, including essential minerals like calcium, phosphorus, and iron, as well as non-essential minerals like lead and arsenic. It is an important parameter to measure in food samples because it can indicate the level of contamination or adulteration and the nutritional value of food.  Principle of ashing: The principle of ashing is based on the process of burning and oxidation of organic matter present in a sample to leave behind only the inorganic mineral content. The organic matter in the sample is converted to carbon dioxide, water vapor, and other gases during the as...

  OBJECTIVE: Estimation of protein by the Biuret method (Qualitative Analysis)  REQUIREMENTS:  Test tubes  Measuring cylinder  Dropper Reagents: Protein Sample  CuSO4 NaOH  THEORY:  This is the most commonly used method based on the fact that the –CO – NH- (peptide) group of proteins forms a purple complex with copper ions in an alkaline medium. Since all proteins contain the peptide bond. The method is fairly specific and there is little interference from other compounds. The normal color of biuret reagent is blue. The reagent turns violet in the presence of peptide bonds. The chemical bonds that hold amino acids together. The proteins detected must have at least 3 amino acids, which mean that the protein must have at least two peptide bonds.  The biuret test uses an alkaline mixture or reagent, composed of sodium hydroxide and copper sulfate.  The reagent used in the Biuret Test is a solution of copper sulfate (CuSO4) and sodium hydrox...

FST Lab 6 (Determination of crude fat by Soxhlet Extraction Method)

By -Published on
OBJECTIVE Determination of crude fat content in food sample through a soxhlet extraction method REQUIREMENTS :  Soxhlet apparatus  Extraction thimbles  Hot plate Petri dishes  Round bottom flask Beaker  Sample  Chemicals:  Solvent (n-hexane) THEORY : The fat content of food is an essential parameter in food analysis as it is one of the key components affecting the nutritional value, quality, and sensory properties of food. The fat content in food is usually determined through various methods, including extraction, gravimetric analysis, and chromatography. Soxhlet extraction is a commonly used method for determining crude fat in food samples. Soxhlet apparatus Soxhlet apparatus is a laboratory apparatus invented by Franz von Soxhlet in 1879. It is used for the extraction of compounds from a solid material.  It consists of three main parts. Thimble: A solid sample is placed in a thimble which is then placed in an extraction chamber  A boiling ...
