Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
81 words
A process for treating poultry carcasses comprising contacting the poultry with a treatment solution having a pH above about 11.5, said solution containing trialkali metal orthophosphate present in an amount of from about 4% or greater based on the weight of the solution, the proviso that the treatment solution does not contain alcohol, said treatment being conducted for a period of time effective to remove, reduce over retard salmonella contamination and/or growth and insufficient to cause organoleptic depreciation of the poultry.
Claim 2
Dependent Claim
81 words
A process for treating poultry carcasses comprising contacting the poultry with a treatment solution having a pH above about 11.5, said solution containing trialkali metal orthophosphate present in an amount of from about 4% or greater based on the weight of the solution, the proviso that the treatment solution does not contain alcohol, said treatment being conducted for a period of time effective to remove, reduce over retard salmonella contamination and/or growth and insufficient to cause organoleptic depreciation of the poultry.
