In 2018, a Utah man was indicted on making threats of mailing ricin to President and the Pentagon.
 
Also in 2018, a couple supporting the so-called “Islamic State” were arrested in Cologne, Germany, for planning a biological attack involving ricin.
 
Two men were sentenced to lengthy prison terms in 2014 for attempting to send then-President Barack Obama packages that were contaminated with ricin.
 
One of the most notorious cases involving the poison was the poisoning of Bulgarian writer Georgi Markov in 1978. He was stabbed with the tip of an umbrella that had a ricin poison packet. He died a few days after he was injected.
