Abstract: Method of injecting treatment solution into slaughtered animals involving electrical stimulation, chilling of the injection solution and use of a self-piercing injection nozzle, among other things.

Abstract: A portable apparatus having a tank having an internally treated surface for containing at least 500 liters, a pump connected to the exit of the tank for pumping solution to a nozzle through a reducing coupling, a water meter means for controlling the quantity of solution entering the steer, a cut-off valve at the water meter, and a cut-off valve at the nozzle, a manometer means for reading pressure passing through the system which is substantially equal to or greater than the pressure developed in the animal's arterial system, and a return pipe from the pump to the tank. By means of the present invention there is provided means for injecting solution into a slaughtered animal when a veterinarian, who controls the quantity of the solution administered according to the weight of the animal such as a steer, and, when the appropriate amount of solution has entered and passed through the steer, the veterinarian closes his valve and the nozzle is shut and removed from the slaughtered animal.
