Control of Enterohemorrhagic E. Coli in Farm Animal Drinking Water

Abstract

The present invention relates to a new composition and methods for preventing the transmission of enterohemorrhagic E. coli and other foodborne pathogens to farm animals. In accordance with one embodiment, a composition comprising lactic acid and acidic calcium sulfate, and a compound selected from the group consisting of caprylic acid, sodium benzoate, butyric acid and chlorine dioxide is provided as an inhibitor of the growth of enterohemorrhagic E. coli and other foodborne pathogens.

1 - 5 . (canceled) 
     
     
         6 . An antimicrobial composition, wherein the composition comprises at least 0.05% lactic acid, at least 0.3% acidic calcium sulfate and at least 0.05% sodium benzoate. 
     
     
         7 . The composition of  claim 6 , wherein the composition comprises about 0.05 to about 1.0% lactic acid, about 0.3% to about 2.0% acidic calcium sulfate and about 0.05 to about 0.2% sodium benzoate. 
     
     
         8 - 9 . (canceled) 
     
     
         10 . A method of decreasing enterohemorrhagic  E. coli  contamination of animal drinking water, said method comprising adding an effective amount of a composition comprising lactic acid, acidic calcium sulfate and sodium benzoate to said drinking water. 
     
     
         11 . The method of  claim 10  wherein the composition comprises about 0.05 to about 1.0% lactic acid, about 0.3% to about 2.0% acidic calcium sulfate and about 0.05 to about 0.2% sodium benzoate. 
     
     
         12 . A method for inhibiting the transmission of enterohemorrhagic  E. coli  to farm animals, said method comprising the steps of contacting farm feeding and watering equipment with a composition comprising lactic acid, acidic calcium sulfate and sodium benzoate. 
     
     
         13 . The method of  claim 12  wherein the composition comprises about 0.05 to about 1.0% lactic acid, about 0.3% to about 2.0% acidic calcium sulfate and about 0.05 to about 0.2% sodium benzoate. 
     
     
         14 . The method of  claim 13  wherein the farm equipment is contacted once a day with said composition. 
     
     
         15 . The method of  claim 14  wherein the farm equipment is contacted with the composition by spraying the composition directly on the equipment. 
     
     
         16 . A method for inhibiting the transmission of enterohemorrhagic  E. coli  to farm animals, said method comprising the steps of contacting the surface of said farm animal's hides with a composition comprising lactic acid, acidic calcium sulfate and sodium benzoate. 
     
     
         17 . The method of  claim 16  wherein the composition comprises about 0.05 to about 1.0% lactic acid, about 0.3% to about 2.0% acidic calcium sulfate and about 0.05 to about 0.2% sodium benzoate. 
     
     
         18 . The method of  claim 17  wherein the surface of said farm animal's hides is contacted with the composition by spraying the composition directly on the animal.
