Patent ID: 8349380

Claim:
A method of controlling bacterial, yeast, and/or mold contamination of seafood or seafood products, which method comprises applying to the seafood or seafood product an aqueous microbiocidal composition formed from components comprising water and at least one microbiocidal component that is selected from: I) at least one solid-state microbiocidal compound having at least one bromine atom in the molecule; II) an aqueous solution or slurry of at least one solid-state microbiocidal compound having at least one bromine atom in the molecule; III) a concentrated aqueous microbiocidal composition having an active bromine content of at least 50,000 ppm, which composition is formed from components comprising water and (i) bromine chloride or bromine chloride and bromine, with or without conjoint use of chlorine and (ii) overbased alkali metal salt of sulfamic acid and/or sulfamic acid, alkali metal base, and water, wherein the relative proportions of (i) and (ii) are such that the atom ratio of nitrogen to active bromine is greater than 0.93, and wherein the pH of the composition is greater than 7; IV) a solid-state microbiocidal composition which is a dewatered concentrated aqueous antimicrobial composition of III) wherein the aqueous microbiocidal composition, upon addition to water, provides in the range of about 0.01 to about 200 ppm (wt/wt) active bromine; and wherein the contact time for the aqueous microbiocidal composition and the seafood or seafood product is in the range of about 10 seconds to about 30 minutes.
