Author 作者: Fermin Barrueto
On 4/16/2013, the United States Capitol Police (USCP) was notified by the Senate mail handling facility that it received an envelope containing a white granular substance. The envelope was immediately quarantined by the facility's personnel and USCP HAZMAT responded to the scene. Preliminary tests indicate the substance found was Ricin.
2013年4月16日，美國參議院郵件處理機構告匯美國國會大廈警察（USCP），他們收到一個信封，里面有白色顆粒狀物質。設施人員將信封立即隔離，USCP危險品控制局馬上到了現場。初步測試表明，該物質是蓖麻毒素。

雖然熱不穩定，容易從蓖麻子豆中提取
No antidote, though Fab like digibind is in development
沒有解藥，雖然與地高辛特異性抗體（digibind）類式的解藥（FAB）正在開發中
Granule size of the grain of sand can kill

Inhalation, IM, IV all effective
吸入，肌注，靜注有同樣效果
After immediate exposure likely no symptoms
