Compositions and methods for lowering counts of pathogenic microorganisms in food products such as ready to eat meat and poultry products are disclosed. In various embodiments, the compositions and methods comprise antimicrobial compositions with one or more essential oils added.

A method treats a food product for increasing the weight of the food product. The food product is an animal carcass, poultry, meat, seafood or parts thereof. The method includes introducing nano-bubbles (NB) into water or an aqueous solution to provide NB-comprising water and contacting the food product with NB-comprising water for a time sufficient to increase the weight of the food product.

A produce wash system is provided. The produce wash system includes a produce line including a short-term wash device and a rinse transition component followed by a wash device, a short-term wash treatment that is applied by the short-term wash device to a product, wherein the short-term wash treatment remains on the product for a pretreatment time that lasts until the short-term wash treatment is rinsed off, and a rinse solution applied by the rinse transition component that rinses the product after the product leaves the short-term wash device and before the product enters the wash device, and a wash treatment that is applied by the wash device to the product, wherein the wash treatment rinses any remaining short-term wash treatment from the product. The pretreatment time is set at or below a damage threshold time beyond which the short-term wash treatment damages the product beyond a damage threshold.

Described is a method of sanitizing animal carcasses using aqueous streams having an antimicrobial composition added to the stream. Preferably, the antimicrobial composition includes a mixture of one or more carboxylic acids having up to 18 carbon atoms and one or more peroxycarboxylic acids having up to 12 carbon atoms, preferably a mixture of a C.sub.2-C.sub.4 peroxycarboxylic acid and a C.sub.8-C.sub.12 peroxycarboxylic acid. Also described is a novel antimicrobial composition adapted for sanitizing animal carcasses containing a mixture of one or more C.sub.2-C.sub.4 peroxycarboxylic acids and one or more C.sub.8-C.sub.12 peroxycarboxylic acids and an alpha-hydroxy mono- or dicarboxylic acid.

A process for reducing the bacterial count on a poultry carcass during poultry processing after the picking stage and prior to the chilling stage by applying an intervention solution having at least one equilibrium peroxycarboxylic acid or a pH modified peroxycarboxylic acid comprising peroxyacetic acid to the poultry carcass at an elevated temperature above 100 F. and at an elevated concentration of at least 200 ppm for a desired period of time of less than about 30 seconds to reduce the bacterial count by at least 60 percent. The process providing acceptable antimicrobial control in poultry processing prior to the chilling stage.

A method of inhibiting the outgrowth of pathogens and spoilage microorganisms in food and beverage products having a moisture content of about 38-80% by weight, a salt content of less than about 5.0% by weight, and a pH range of about 4.6 to about 8.5. The application of an organic acid or its salt with a fermentation derived antimicrobial peptide offers a robust solution to curtail growth of spores and vegetative cells without the need for chemicals, such as sodium nitrite, sodium nitrate or sorbate.
