Abstract
Abstract Rapid destruction of microorganisms is obtained by contacting microorganisms in the presence of water with a halocyanoacetamide such as 2,2-dibromo-2-cyanoacetamide and at least 0.5 mole of a water soluble bromide or iodide salt such as sodium iodide per mole of halocyanoacetamide.
