## Abstract

A process for treating animals and/or seafood comprising the step of contacting the animal and/or seafood with a treatment solution containing trialkali metal orthophosphate at a temperature of between about 90.degree. F. and about 200.degree. F. for a time period effective to remove, reduce or retard bacterial contamination without significantly depreciating the organoleptic properties of the animal and/or seafood is provided.

## Claims

### Claim 1

A process for treating animals and/or seafood comprising the step of contacting the animal and/or seafood with a treatment solution containing trialkali metal orthophosphate at a temperature of between about 90.degree. F. and about 200.degree. F. for a time period effective to remove, reduce or retard bacterial contamination without significantly depreciating the organoleptic properties of the animal and/or seafood and wherein the concentration of said trialkali metal orthophosphate in said solution is between less than about 0.1 to about 4.0 percent by weight.

### Claim 2 (depends on 1)

The process according to claim 1 wherein the concentration of trialkali metal orthophosphate in said solution is from about 0.25 percent by weight to less then about 4.0 percent by weight.

### Claim 3 (depends on 2)

The process according to claim 2 wherein the concentration of trialkali metal orthophosphate in said solution is from about 0.50 percent by weight to less than about 4.0 percent by weight.

### Claim 4 (depends on 3)

The process according to claim 3 wherein the concentration of trialkali metal orthophosphate in said solution is from about 1.0 percent by weight to less than about 4.0 percent by weight.

### Claim 5 (depends on 1)

The process according to claim 1 wherein said trialkali metal orthophosphate comprises trisodium orthophosphate.

### Claim 6 (depends on 1)

The process according to claim 1 wherein the pH of said treatment solution is greater than about 11.5.

### Claim 7 (depends on 5)

The process according to claim 5 wherein the pH of said treatment solution is between about 12 and about 13.5.

### Claim 8 (depends on 1)

The process according to claim 1 wherein said treatment solution does not contain alcohol.

### Claim 9 (depends on 1)

The process according to claim 1 wherein said poultry, red meat or seafood comprises a poultry carcass and wherein said treatment solution is applied prior to chilling said carcass.

### Claim 10 (depends on 1)

The process according to claim 1 wherein said poultry, red meat or seafood comprises red meat and wherein said treatment solution is applied prior to rigor.

### Claim 11 (depends on 1)

The process according to claim 1 wherein said poultry, red meat or seafood comprises seafood and wherein said treatment solution is applied after evisceration.

### Claim 12 (depends on 1)

The process according to claim 1 wherein the temperature of said solution is between about 100.degree. F. and about 180.degree. F.

### Claim 13 (depends on 13)

The process according to claim 13 wherein the temperature of said solution is between about 125.degree. F. and about 175.degree. F.

### Claim 14 (depends on 13)

The process according to claim 13 wherein the temperature of said solution is between about 140.degree. F. and about 160.degree. F.
