Ricin

Although ricin's history as a biologic weapon consists only of discrete episodes of poisoning, its widespread availability and ease of manufacture make it a viable terrorist threat. Clinicians must maintain a low threshold of suspicion for patients presenting with non-specific systemic illnesses, and be especially vigilant regarding large numbers of patients exhibiting gastrointestinal or pulmonary symptoms. The authors have outlined a plan of supportive care and diagnostic testing, that, along with a comprehensive differential diagnosis, should aid physicians in diagnosing and treating terrorist incidents involving ricin.
