Fecal bacterial contamination in an animal is reduced by providing it with drinking water containing a microbiocidally-effective amount of halogen-based microbiocide resulting from mixing with water (A) a product formed in water from (i) bromine, chlorine, or bromine chloride, or any two or more thereof, (ii) a water-soluble source of sulfamate anion, and (iii) a water-soluble base; (B) at least one 1,3-dihalo-5,5-dialkylhydantoin in which one of the halogen atoms is a chlorine atom and the other is a chlorine or bromine atom, and in which each alkyl group, independently, contains in the range of 1 to about 4 carbon atoms; (C) at least one 1,3-dibromo-5,5-dialkylhydantoin in which one of the alkyl groups is a methyl group and the other alkyl group contains in the range of 1 to about 4 carbon atoms; or (D) any two or more of (A), (B), and (C).

1. A method of reducing fecal contamination in an animal, which method comprises providing to the animal drinking water containing a microbiocidally-effective amount of halogen-based microbiocide resulting from mixing with water at least one 1,3-dibromo-5,5-dialkylhydantoin in which one of the alkyl
1. A method of reducing fecal contamination in an animal, which method comprises providing to the animal drinking water containing a microbiocidally-effective amount of halogen-based microbiocide resulting from mixing with water at least one 1,3-dibromo-5,5-dialkylhydantoin in which one of the alkyl groups is a methyl group and the other alkyl group contains in the range of 1 to about 4 carbon atoms.2. A method according to claim 1 wherein said at least one 1,3-dibromo-5,5-dialkylhydantoin in the form of solids or as a water solution or slurry formed from said at least one 1,3-dibromo-5,5-dialkylhydantoin, is mixed with water and optionally the water mixture is further diluted one or more times with water, to provide said microbiocidally-effective amount of halogen-based microbiocide in said drinking water.3. A method according to claim 1 wherein said at least one 1,3-dibromo-5,5-dialkylhydantoin before it is mixed with any water is 1,3-dibromo-5,5-dimethylhydantoin.4. A method according to claim 1 wherein said at least one 1,3-dibromo-5,5-dimethylhydantoin before it is mixed with any water is a mixture of 1,3-dibromo-5,5-dimethylhydantoin and 1,3-dibromo-5-ethyl-5-methylhydantoin.5. A method according to claim 3 wherein said 1,3-dibromo-5,5-dimethylhydantoin before it is mixed with any water is in the form of granules having a compression strength of at least about 15 pounds per inch and wherein said granules are devoid of any binder or other component tending increase the compression strength of the granules.6. A method according to any of claim 1, 2, 3, 4 or 5, wherein said animal is poultry, swine, sheep, or cattle.7. In the processing of at least one animal for at least one meat product, the improvement which comprises reducing fecal contamination in said at least one animal prior to slaughter, which method comprises providing to the animal as its exclusive or substantially exclusive source of drinking water during a period prior to slaughter, drinking water containing a microbiocidally-effective amount of halogen-based microbiocide resulting from mixing with water at least one 1,3-dibromo-5,5-dialkylhydantoin in which one of the alkyl groups is a methyl group and the other alkyl group contains in the range of 1 to about 4 carbon atoms.8. The improvement according to claim 7 wherein said at least one animal is poultry, swine, sheep, or cattle.9. The improvement according to claim 7 wherein said microbiocidally-effective amount of halogen-based microbiocide in said drinking water is in the range of about 1 to about 100 ppm (wt/wt) expressed as Br2.10. The improvement according to claim 7 wherein said microbiocidally-effective amount of halogen-based microbiocide in said drinking water is in the range of about 4 to about 30 ppm (wt/wt) expressed as Br2.11. The improvement according to claim 7 wherein said microbiocidally-effective amount of halogen-based microbiocide results from use of 1,3-dibromo-5,5-dimethylhydantoin as the microbiocide that is mixed with water.12. The improvement according to any of claims 7, 8, 11 wherein said at least one animal is fowl, swine, sheep, or cattle, and wherein said microbiocidally-effective amount of halogen-based microbiocide in said drinking water is in the range of about 1 to about 100 ppm (wt/wt) expressed as Br2.13. The improvement according to claim 12 wherein said microbiocidally-effective amount of halogen-based microbiocide in said drinking water is in the range of about 4 to about 30 ppm (wt/wt) expressed as Br2.14. The improvement according to claim 12 wherein said microbiocidally-effective amount of halogen-based microbiocide in said drinking water is in the range of about 4 to about 50 ppm (wt/wt) expressed as Br2.15. A method of preparing drinking water for animals to be processed for at least one meat product, the improvement which comprises introducing into said drinking water a microbiocidally-effective amount of at least one 1,3-dibromo-5,5-dialkylhydantoin in the form of solids or as a water solution or slimy formed from said at least one 1,3-dibromo-5,5-dialkylhydantoin, wherein before introduction into any water said at least one 1,3-dibromo-5,5-dialkylhydantoin has a methyl group as one of its alkyl groups and an alkyl group containing in the range of 1 to about 4 carbon atoms as its other alkyl group.16. The improvement according to claim 15 wherein said microbiocidally-effective amount of halogen-based microbiocide results from use of 1,3-dibromo-5,5-dimethylhydantoin as the microbiocide that is mixed with water.17. The improvement according to either of claim 15 or 16 wherein said at least one animal is poultry, swine, sheep, or cattle, and wherein said microbiocidally-effective amount of halogen-based microbiocide in said drinking water is in the range of about 1 to about 100 ppm (wt/wt) expressed as Br2.18. The improvement according to claim 17 wherein said microbiocidally-effective amount is in the range of about 4 to about 30 ppm (wt/wt) expressed as Br2.19. The improvement according to claim 17 wherein said microbiocidally-effective amount is in the range of about 4 to about 50 ppm (wt/wt) expressed as Br2.20. A method for reducing fecal contamination in animals to be processed for at least one meat product, which method comprises:A) preparing drinking water for said animals by introducing into said water a microbiocidally-effective amount of at least one 1,3-dibromo-5,5-dialkylhydantoin in which one of the alkyl groups is a methyl group and the other alkyl group contains in the range of 1 to about 4 carbon atoms to form microbiocidally-treated drinking water; and B) providing microbiocidally-treated drinking water from A) to said animals prior to processing said animals for at least one meat product. 21.
