Ricin is a protein toxin, not an infectious agent. Illness occurs only after someone is exposed to the toxin source—through ingestion, inhalation, or injection of ricin-containing material. Because it does not replicate or spread like a pathogen, there is no mechanism for ricin intoxication to be transmitted from one person to another. In a scenario where an aerosolized ricin release affects several people, those affected are exposed to the toxin environment, not infected through person-to-person transmission. So the statement is false.
