Biological toxins are a heterogeneous group produced by living organisms. One dictionary defines them as “Chemicals produced by living organisms that have toxic properties for another organism”. Toxins are very attractive to terrorists for use in acts of bioterrorism.

What is considered a biological toxin?
Biological toxins consist of any toxic substance produced by microorganisms, plants, or animals. They include metabolites of living organisms, degradation products of nonliving organisms, and those materials rendered toxic by the metabolic activity of microorganisms. Most toxins are highly toxic in minute quantities.
What are 3 examples of biological toxins?
Biological toxins are poisonous substances produced by certain microorganisms, animals, and plants. Examples of toxins of biological origin include Diphtheria Toxin, Tetrodotoxin, Pertussis Toxin, Botulinium Toxin, Snake Venom Toxins, Conotoxin and Ricin.
What are the sources of biological toxins?
Biological toxins are produced by certain bacteria, fungi, protozoa, plants, reptiles, amphibians, fish, echinoderma (spiny urchins and starfish), mollusks, and insects.
What are biological toxicants?
Biological toxins are hazardous substances produced by microorganisms, animals, insects, and plants that can be harmful when inhaled, ingested, injected, or absorbed.
Which biological toxin is used most of the time in the United States?
Killer Strain: Anthrax Anthrax is the most likely agent to be used in a biological attack. It only takes a small amount to infect a large number of people. Learn more about anthrax and how CDC is prepared for a possible attack.
What are the four major types of toxic substances?
Types. There are generally five types of toxic entities; chemical, biological, physical, radiation and behavioural toxicity: Disease-causing microorganisms and parasites are toxic in a broad sense but are generally called pathogens rather than toxicants.
What toxin mean?
: a poisonous substance that is a specific product of the metabolic activities of a living organism and is usually very unstable, notably toxic when introduced into the tissues, and typically capable of inducing antibody formation.
How can we reduce our biological toxins?
Properly cooking and cooling foods and avoiding cross-contamination generally will prevent the growth of most bacteria and fungi. Foods should be cooked at the temperatures listed in their directions and for the appropriate amount of time to kill bacteria.
Where do toxic chemicals come from?
Chemicals can enter the environment from many different sources such as landfills, incinerators, tanks, drums, or factories. Human exposure to hazardous chemicals can occur at the source or the chemical could move to a place where people can come into contact with it. Chemicals can move through air, soil, and water.
Is a virus a biological agent?
Biological agents include bacteria, viruses, fungi, other microorganisms and their associated toxins. They have the ability to adversely affect human health in a variety of ways, ranging from relatively mild, allergic reactions to serious medical conditions—even death.
How do biological agents enter the body?
There are four major routes by which a chemical may enter the body: Inhalation (breathing) Skin (or eye) contact. Swallowing (ingestion or eating)
What are disease causing biological agents called?
A biological agent is an infectious disease or toxin that can be used in bioterrorism or biological warfare or can be encountered in workplace setting. There are more than 1200 different kinds of biological agents. Biological agents include bacteria, viruses, fungi, other microorganisms and associated toxins.
What is a toxin and what does it do?
+ Create new collection. Poisons are substances that cause harm to organisms when sufficient quantities are absorbed, inhaled or ingested. A toxin is a poisonous substance produced within living cells or organisms.
What is the definition of biological terrorism?
Bioterrorism is a form of terrorism where there is the intentional release of biological agents (bacteria, viruses, or other germs). This is also referred to as germ warfare.
What are the two types of toxicity?
The two types of toxicity are acute and chronic. Acute toxicity of a pesticide refers to the chemical’s ability to cause injury to a person or animal from a single exposure, generally of short duration. The four routes of exposure are dermal (skin), inhalation (lungs), oral (mouth), and eyes.
