Abstract
Compositions and methods are disclosed for improving food safety. One or more lactic acid producing microorganisms are shown to inhibit pathogenic contaminations on food materials. The lactic acid producing microorganisms are capable of adhering to various surfaces and may serve as a bio-sanitizing agent (or bio-sanitizer). Lactic acid producing microorganisms or cell free extract of these microorganisms may be used in an effective and natural method to prevent L. monocytogenes infection in food products, as well as in food processing facilities and equipments.
Claims24
A method for improving food safety, said method comprising a step of contacting a surface with a composition, said composition comprising at least one lactic acid producing microorganism, said at least one lactic acid producing microorganism being present in said composition in an amount effective in preventing or disrupting formation of biofilm by a pathogenic bacterium on said surface, wherein said surface is the interior or exterior surface of an object, said object being selected from the group consisting of a food material, a food processing equipment, a food processing platform, a food processing tool, a food processing room, a food container, and combination thereof.
A method for reducing the amount of a pathogen in a food material, said method comprising:
- contacting said food material with a composition, said composition comprising at least one lactic acid producing microorganism, said at least one lactic acid producing microorganism being present in said composition in an amount effective in reducing the number of said pathogen in said food material.
A method for reducing the amount of a pathogen in a food material, said method comprising:
- contacting said food material with a composition, said composition comprising a cell-free supernatant (CSF) obtained from at least one lactic acid producing microorganism, said CSF being present in said composition in an amount effective in reducing the number of said pathogen in said food material.
A composition comprising a cell-free supernatant (CFS) obtained from a lactic acid bacterium.
