Methods of processing four-legged animals are described. The methods comprise contacting a carcass of an animal, after exsanguination, with a microbiocidal solution, and/or contacting at least one raw meat product and/or at least one processed meat product derived from the carcass with a microbiocidal solution. Each microbiocidal solution is, independently, comprised of: water having a bromine residual derived from (a) (i) at least one bromine source, (ii) at least one alkali metal base, and/or at least one alkaline earth metal base, and (iii) at least one halogen stabilizer (b) (i) at least one alkali metal bromide, and/or at least one alkaline earth metal bromide, and (ii) at least one alkali metal hypohalite and/or at least one alkaline earth metal hypohalite or (c) a mixture or combination of one or more of (a) and/or (b) the bromine residual in each (a), (b), and (c) sufficient to provide microbiocidal activity.
