Despite the presence of the cyanide ion, Prussian Blue, like other ferro- and ferri-cyanides, is not especially toxic due to the strong binding between the cyanide and ferrous or ferric (iron) ions. However, treatment with acids can liberate the cyanide in the form of hydrogen cyanide, which is extremely toxic.

Because of the above mentioned there is a controversy among pseudo-scientists trying to disprove the holocaust. It is a common argument that because the levels of cyanide (Prussian blue) are higher on the walls of the delousing chambers than the homicide chambers, the homicide chambers were not used to any extent. Anyone that understands the properties of iron bonded cyanide and cyanide gas can easily refute this.
