Rhodesian Security Forces
Biological agents, namely "Vibrio cholerae" (causative agent of cholera), had some impact on the fighting capability of ZANLA. Some former officers of the Rhodesian Security Forces alleged that anthrax was used covertly during the late 1970s, but this has been disputed. Use of "anthracis", ricin, or botulinum toxin was favoured during assassination attempts of prominent guerrilla commanders.
