Abstract: A poultry euthanasia device in which hens pass on belts though a gas proof enclosure with increasing concentration levels of toxic gas for more humane euthanasia, and exit the machine deceased. The device has an entry chute which is connectable to a hen house located to either side of the unit, or behind the unit. A number of belts carry the hens through the machine, and they painlessly go to sleep and die due to a high CO2 atmosphere.

Abstract: A method and apparatus (10) for scalding and plucking slaughtered poultry, by way of example chickens, hens, turkeys, ducks or geese, where the poultry is transported via a sluice device through a scalding tunnel (10) are slaughtering, preferably suspended at the feet, where the poultry in the scalding runnel is conveyed successively between rows of nozzles (36) that are adapted to apply scalding agent to the poultry, where a plurality of different scalding agents are applied, where in a first scalding zone hot water is used as scalding agent, where in succeeding scalding zones scalding agents with mutually differing temperatures are applied, where in the said succeeding scalding zones warm humid air is used as scalding agent which is at least blown onto specific sub areas of the poultry. In a simple way optimal plucking may occur subsequently without the poultry subjected to unnecessary heat action, and so that a considerable reduction of the required energy consumption is simultaneously attained.

Abstract: Disclosed is a novel method and system for dehairing an animal, providing a system for recycling and safely disposing of chemical and biological wastes produced during such dehairing method. Included in such method are processes for handling sodium production in waste materials, reducing and handling production of H2S, removing sulfides from animal hides, safely disposing of sulfide waste, removing solids from the waste materials, and reducing water and reagent use and disposal.

Abstract: In the inventive method for the sanitary rinsing of an animal, an assembly line is provided which includes a plurality of shackles. Each shackle includes an inventive tag which includes a machine readable unique shackle number. Once an animal is stunned and attached to a shackle the animal is moved to a weighing station, which is equipped with a tag reader, weighs the animal and transmits the weight and shackle number to a computer where the data is recorded in a database. The animal is then bled and moved to a rinsing station, which is equipped with a tag reader which reads the shackle number. The system then looks up the weight of the animal to be rinsed at that particular rinsing station and calculates the amount of solution to inject into the circulatory system of the animal.

Included in such method are processes for handling sodium production in waste materials, reducing and handling production of H.sub.2 S, removing sulfides from animal hides, safely disposing of sulfide waste, removing solids from the waste materials, and reducing water and reagent use and disposal.

Abstract: An apparatus used for reducing the amount of pathogenic bacteria associated with a bird or other edible animal, and preferably chickens, comprising: (a) a unit having an interior portion having side and bottom walls, an exterior portion having side and bottom walls and end walls connecting said interior portion to said exterior portion wherein the area of said interior portion provides a space which completely surrounds one or more of the birds or animals being treated; (b) one or more flood nozzles mounted within said interior portion of said unit and connected to a source of a bacteria reducing chemical solution to enable the bacteria reducing chemical solution to be applied to the entire interior of the body cavity of the bird or animal being treated; (c) one or more spray nozzles mounted within said interior portion of said unit and connected to a source of a bacteria reducing chemical solution to enable the bacteria reducing chemical solution to be applied to the entire external surfaces of the bird or a
