Police say Chetanand Sewraz was manufacturing Ricin at his Brandermill home. Ricin is a deadly toxin that can kill, even in small amounts. It's a byproduct if you're making castor oil from castor beans. Once the oil is removed you have 5% ricin in the pulp. That 5% is extremely toxic. According to police, Sewraz had a small amount of ricin in mash form.
Health officials say ricin is dangerous if inhaled or injected. The poison is not dangerous if you get it on your skin. Dr. William Nelson, Health Director for Chesterfield County says that the community is not in danger from the ricin Sewraz is charged with manufacturing because the material wasn't leaked into the population.
