Antimicrobial formulations and solutions for food safety and quality applications are disclosed. Because some of these formulations and solutions contain a substantial concentration of salt, they are adaptable to a variety of food-processing applications, such as for chilling brine applications, disinfecting meat baths/rinses, beef injection brines, poultry chill tanks, brines used in cheese manufacture, as a wash to kill salmonella and other bacteria on hard-boiled eggs or egg shells, and as a wash to disinfect produce, which can become contaminated with salmonella and other pathogenic bacteria in the field. These uses of concentrated salt solutions that depress the freezing point of the solution provide a low temperature bath or shower in which food products can be cooled. One embodiment comprises between 25 ppm and 100,000 ppm surfactant and between 72% and 99.99% salt. This blend can then be dissolved in water to make a solution of between about 1% total solids by weight up to the saturation point, which can be used as an antimicrobial solution for food safety applications.

1. An antimicrobial solution comprising on a dry basis: between about 100 ppm and about 1000 ppm surfactant selected from the group consisting of CH3(CH2)10-0(CH2CH2O)yH, where y=average moles of ethoxylation and is in the range 3-9; andbetween about 94% and about 99.9% by weight salt selected from
1. An antimicrobial solution comprising on a dry basis: between about 100 ppm and about 1000 ppm surfactant selected from the group consisting of CH3(CH2)10-0(CH2CH2O)yH, where y=average moles of ethoxylation and is in the range 3-9; andbetween about 94% and about 99.9% by weight salt selected from the group consisting of sodium, potassium, magnesium, calcium, iron, ammonium salts of chloride, sulfate, nitrate, phosphate, carbonate, acetate, formate, propionate, hydroxypropionate, and hydroxide. 2. The solution of claim 1 wherein the surfactant and salt in combination comprise at least about 2% by weight of the solution. 3. The solution of claim 1 wherein the surfactant and salt in combination comprise at least about 5% by weight of the solution. 4. A method for food processing comprising: contacting a food product to be processed with a chilling solution wherein the chilling solution comprises a combination of:a surfactant selected from the group consisting of CH3(CH2)10—O(CH2CH2O)yH, where y=average moles of ethoxylation and is in the range 3-9; anda salt selected from the group consisting of sodium, potassium, magnesium, calcium, iron, and ammonium salts of chloride, sulfate, nitrate, phosphate, carbonate, acetate, formate, propionate, hydroxypropionate, and hydroxide,wherein the salt and surfactant are on a dry basis between about 25 ppm and about 100,000 ppm by weight surfactant and between about 94% and about 99.9% by weight salt. 5. The method of claim 4 wherein the ratio of the salt to the surfactant of the chilling solution is greater than about 29:1 by weight. 6. The method of claim 4, wherein the chilling solution is maintained at a temperature of less than about 0° C. 7. The method of claim 4, wherein the chilling solution is maintained at a temperature of less than about −6.7° C. 8. The method of claim 4 wherein the surfactant and salt in combination comprise at least about 2% by weight of the chilling solution. 9. The method of claim 4 wherein the surfactant and salt in combination comprise at least about 5% by weight of the chilling solution.
