(CIDRAP News) A Las Vegas man remained unconscious today with suspected ricin poisoning after the deadly toxin derived from castor beans was found in his Las Vegas motel room last week, according to news services.
(CIDRAP News) The FBI this week released a photo of a letter addressed to the White House last fall that contained ricin and threatened to "turn D.C. into a ghost town" if new trucking regulations went into effect.
The letter stated, "If you change the hours of service on January 4, 2004 I will turn D.C. into a ghost town. The powder on the letter is RICIN have a nice day Fallen Angel."
(CIDRAP News) One of three Senate office buildings that were closed this week after ricin was found in an office was set to reopen today, but the source of the ricin remained a mystery.
(CIDRAP News) Because someone who recently mailed a container of ricin remains at large, the Centers for Disease Control and Prevention (CDC) is urging health workers to be alert for possible cases of ricin poisoning.
Environmental tests showed no signs of ricin contamination at an airport mail facility in Greenville, S.C., where an envelope containing the poison was found last week, according to the US Postal Service (USPS).
