The FBI is looking into sending letters with ricin to the White House

US intelligence agencies intercepted a parcel with ricin sent to the address of US President Donald Trump.

A suspicious package was discovered this week when checking incoming mail. The study found that the envelope contained ricin, a protein poison derived from castor beans.

The Trump administration has yet to comment on the incident.

The FBI and the US Secret service are trying to find out where the package was sent from and whether there are other similar items in the country’s postal system.

“At this time, we do not see any threats to public safety,” CNN quoted the FBI.

A source for the New York Times claims that the package was allegedly sent from Canada. According to preliminary information, ricin in the package was detected as a result of two tests.

Ricin is a deadly poison. If swallowed, inhaled, or injected, it causes headaches, nausea, internal bleeding, and organ failure.

There is no antidote to ricin. If a person has taken this poison, death occurs within 36-72 hours, depending on the dose received.

Ricin can be used as a powder, aerosol, or granule.
