BBC Story - Ricin 'antidote' to be produced

Thank you to a reader who also has the name Sherry, for bringing this article to our attention.

This, does not have anything to do with the Ukraine directly, but it is one of those articles and news information - where you have to ask "Why"? Why are they creating an Antidote to Ricin? What kind of information do they know - we do not? Also Why, are they releasing this information?

Click on the headline to see the full story - here is some of it.

An anti-toxin that protects against ricin poisoning is to move into production for the first time.

It is the result of eight years of work by researchers at the Defence Science and Technology Laboratory based at Porton Down in Wiltshire.

Security experts say ricin - roughly 1,000 times more toxic than cyanide - could be used in a bio-terror attack.

Dr Holley told BBC News: "In the past there has been lots of research carried out using different methods. But this is the first [anti-toxin] that has been moved into production.

The principal scientist in biomedical sciences at DSTL added: "It is anticipated that a product will be available for use in the next couple of years."

Ricin is extracted from castor beans, which are processed throughout the world to make castor oil. The toxin is part of the waste "mash" produced when castor oil is made.

It can cause harm if injected, swallowed or inhaled. But the amount needed to kill depends on the route of administration.

A combination of pulmonary, liver, renal and immunological failure can lead to death, though people can recover from exposure.

In recent years, the perceived threat of bioterrorism has increased.

Although the anti-toxin developed at Porton Down was initially intended for use by the military, DSTL scientists are investigating its potential use in a civilian environment.

Production of the anti-toxin involves immunising sheep with an inactive form of ricin, which results in the production of antibodies. These are proteins used by the immune system to neutralise harmful substances.

The antibodies are then harvested from the sheep to produce a freeze-dried product. This is reconstituted with water for injection into the body.

See the full article at link - also, I have to admit - I have literally laughed with the use of Sheep for the antitoxin, funny they use the word here and they use sheep for the testing.
