Ricin is one of the most deadly poisons in the world and can exist in the form of a pellet, mist, or powder. Some symptoms of exposure can include vomiting and dehydration, sweating, nausea, fever, cough and difficulty of breathing.

Last year there were similar false positive reports of ricin in London, which were further publicized by Vice President Cheney and Secretary of State Colin L. Powell.
