Meat processing methods providing reduced contamination from microbial sources, improved tenderness of the resulting meat product, and enhanced processing efficiency by decreasing cost, water usage, wastewater output, time, and energy necessary for processing meat carcasses are disclosed. The methods utilize hot water spray of the carcass in addition to subzero chilling. The methods reduce bacterial population during meat production, including both Gram-negative and Gram-positive bacteria. The hot water also cleans the carcass before exposure to the chilled water such that the chilled water can be used repeatedly.

A system and method for creating an oxidation reduction potential (ORP) in water and for reducing the surface tension of the water for the microbiological decontamination of food animal carcasses. A method is also described for the microbiological decontamination of beef trimmings.

A method for treating an animal carcass (3) after slaughtering, comprising: a) placing the carcass (3) into a chamber (2), and b) disinfecting the carcass (3) within the chamber (2) by maintaining an oxygen concentration within the chamber (2) above 20% and maintaining a temperature of the carcass (3) above 10° C. With the described method and use an animal carcass (3) can be disinfected particularly efficiently, in particular with respect to campylobacter bacteria. Therefore, the carcass (3) is subjected to an oxygen concentration above 20% and to a temperature above 10° C.

A diagnostic system for processing animal carcass, wherein the system comprises an artificial animal carcass that includes a bladder inside; a sensory module under the exterior surface of artificial animal carcass; and a display module operably coupled with the sensory module. The bladder inside the artificial animal carcass is configured to be filled with water at the slaughter facility, so that the weight of artificial carcass is approximately the same as the weight of real carcass to be processed. The sensory module is configured to measure a selected parameter on the surface of artificial animal carcass to be displayed on the display module.

Embodiments of the invention relates to an antimicrobial composition comprising an alkyl pyrazine compound or mixture of compounds selected from the group consisting of 2-isobutyl-3-methylpyrazine, 2-isobutyl-3-methoxypyrazine, 2-isopropylpyrazine, 2-isobutylpyrazine and mixtures of methylpyrazines having one, two and three isopropyl or isobutyl substituents. Further embodiments of the invention relate to uses of alkyl pyrazine compounds, in particular for controlling microbial growth.

A system and method for creating an oxidation reduction potential (ORP) in water and for reducing the surface tension of the water for the microbiological decontamination of food animal carcasses. A method is also described for the microbiological decontamination of beef trimmings.

A method for processing an intact animal carcass comprises submerging a bled animal carcass in scalding water for at least 20 seconds to produce a scalded animal carcass, de-hairing the scalded animal carcass to produce a de-haired animal carcass, suspending the de-haired animal carcass, burning an epidermal layer of the de-haired animal carcass while suspended so that a majority of the epidermal layer is charred so as to produce a burnt animal carcass, pressure washing the burnt animal carcass to produce a pressure-washed animal carcass, eviscerating the pressure-washed animal carcass to produce an eviscerated animal carcass, internally washing the eviscerated animal carcass to produce an internally washed animal carcass, and chilling the internally washed animal carcass to a temperature of between 0 degrees Celsius and about 4 degrees Celsius to produce a chilled animal carcass.

A carcass cleaning system. Specifically, a system for cleaning an animal carcass using potable water passed through an offline treatment system and the application of this treated water to the surface of the carcass, for example, by running through a bath or by spraying or nebulisation at or onto the surface of the carcass. The invention finds utility in the fields of butchery and slaughtering o animals in the preparation for

Embodiments of the invention relates to an antimicrobial composition comprising an alkyl pyrazine compound or mixture of compounds selected from the group consisting of 2-isobutyl-3-methylpyrazine, 2-isobutyl-3-methoxypyrazine, 2-isopropylpyrazine, 2-isobutylpyrazine and mixtures of methylpyrazines having one, two and three isopropyl or isobutyl substituents. Further embodiments of the invention relate to uses of alkyl pyrazine compounds, in particular for controlling microbial growth.

Compositions and methods for cleaning and decontaminating animal carcasses are disclosed. The compositions comprise a mud ball remover having a thioglycolate salt and a base and an antimicrobial agent effective to remove mud balls and reduce microbial contamination of a hide surface at ambient temperatures. The methods comprise cleaning and decontaminating an animal carcass by applying the disclosed compositions onto the surface of the animal carcass to soften and loosen foreign debris attached to the carcass followed by mechanically removing the foreign debris while preserving the integrity and quality of the hide byproduct and resulting leather articles.
