Microbiocidal Control in the Processing of Poultry

A process which comprises placing at least one eviscerated poultry carcass in a chill tank and into contact with chill water, the chill water containing a microbiocidal composition or

• subjecting at least one eviscerated poultry carcass to inside-outside washing with water containing a microbiocidal composition,
• characterized in that the microbiocidal composition comprises:
• I) one or more surfactants which is one or more amine oxides having about eight to about twenty carbon atoms, and/or one or more betaines having about eight to about twenty carbon atoms;
• and
• II) a microbiocidal amount of:
• (1) one or more 1,3-dibromo-5,5-dialkylhydantoins;
• (2) one or more N,N′-bromochloro-5,5-dialkylhydantoins;
• (3) chlorine dioxide;
• (4) chlorine;
• (5) hypochlorous acid formed by electrolysis;
• (6) one or more alkali metal hypochlorites and/or one or more alkaline earth metal hypochlorites;
• (7) monochloramine;
• (8) peracetic acid;
• or (9) a bromine-based biocide formed in water from
• A) (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 (i) and (ii) are in relative proportions such that there is an atom ratio of nitrogen to active bromine greater than 0.93, and wherein the bromine-based biocide has a pH of greater than 7;
• or
• B) (i) one or more bromide sources selected from ammonium bromide, hydrogen bromide, at least one alkali metal bromide, one or more alkaline earth metal bromides, and mixtures of any two or more of the foregoing, (ii) a chlorine source, (iii) optionally at least one inorganic base, and (iv) optionally sulfamic acid and/or a metal salt of sulfamic acid.

A process which comprises contacting at least one unopened defeathered poultry carcass with water containing a microbiocidal composition, whereby the exterior of said carcass is wetted by such composition, characterized in that the microbiocidal composition comprises

• I) one or more surfactants which is one or more amine oxides having about eight to about twenty carbon atoms, and/or one or more betaines having about eight to about twenty carbon atoms;
• and
• II) a microbiocidal amount of:
• (1) one or more 1,3-dibromo-5,5-dialkylhydantoins;
• (2) one or more N,N′-bromochloro-5,5-dialkylhydantoins;
• (3) chlorine dioxide;
• (4) chlorine;
• (5) hypochlorous acid formed by electrolysis;
• (6) one or more alkali metal hypochlorites and/or one or more alkaline earth metal hypochlorites;
• (7) monochloramine;
• (8) peracetic acid;
• or (9) a bromine-based biocide formed in water from
• A) (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 (i) and (ii) are in relative proportions such that there is an atom ratio of nitrogen to active bromine greater than 0.93, and wherein the bromine-based biocide has a pH of greater than 7;
• or
• B) (i) one or more bromide sources selected from ammonium bromide, hydrogen bromide, one or more alkali metal bromides, one or more alkaline earth metal bromides, and mixtures of any two or more of the foregoing, (ii) a chlorine source, (iii) optionally at least one inorganic base, and (iv) optionally sulfamic acid and/or a metal salt of sulfamic acid.
