A new report by CBS news says the next terrorist might not come by land or sea, but rather salad greens.
The news outlet says it has confirmed "credible" threats that terrorists are now looking to target Americans by lacing buffets and salad bars with poison such as ricin and cyanide.
CBS News reports:
Of particular concern: The plotters are believed to be tied to the same terror group that attempted to blow up cargo planes over the east coast in October, al Qaeda in the Arabian Peninsula.
In online propaganda al Qaeda in the Arabian Peninsula has praised the cargo attack, part of what it called "Operation Hemorrhage."
The propaganda says in part, "...attacking the enemy with smaller but more frequent operations" to "add a heavy economic burden to an already faltering economy."
Manuals and videos on jihadist websites explain how to easy it is to make both poisons.
"Initially it would look very much like food poisoning," said St. John's University professor of pharmaceutical sciences Dr. Susan Ford.
She showed how little of each poison could be fatal by putting a small amount of poison in cups.
Armen Keteyian: Are these dosages enough to really harm someone or kill someone?
Susan Ford: Yes, these are 250 milligrams and that is the fatal dose.
Keteyian: So just that much sodium cyanide is enough to kill me?
Ford: Yes, it is.
