Apparently no-one in the FDA can say why or whether Vegemite is restricted. I suspect it was a security alert that was misconstrued.

Someone found out that if you add six ounces of Vegemite to a kilo of Torpex or plastique, you get about the yield of a kilo of Torpex or plastique. This is obviously too dangerous to leave in the hands of irresponsible Aussies.
