PROBLEM TO BE SOLVED: To provide stabilized chlorine dioxide and hypochlorous acid in a liquid biocide. SOLUTION: The liquid biocide contains stabilized chlorine dioxide and hypochlorous acid for various uses including a use as a teat dip for dairy animals. This is a stable prophylactic biocide essentially consisting of 0.10-20.0 mass% of a chlorite salt, 0.1-3.0 mass% of an acid, 0.10-2.0 mass% of an alkaline agent, and the balance water. The chlorite salt reacts with the acid to form germicidal chlorine dioxide and hypochlorous acid. The acid component and the alkaline agent component regulate the pH of the solution such that the biocide is stable when mixed for a period of two months or longer. The present disclosure also includes a method of producing a stable and prophylactic biocide for dairy cattle. The method includes mixing 0.10-20.0 mass% of a chlorite salt, 0.10-3.0 mass% of an acid, 0.10-2.0 mass% of an alkaline agent, and the balance water, and sealing the mixture in a container. In the method, the acid component and the alkaline agent component regulate the pH of the solution such that the formation of hydronium ions from the acid is correspondingly regulated to stabilize the solution for a period of two months or longer from the date of sealing.
