The present disclosure includes various method, device, and system embodimentsfor meat processing. One such method embodiment includes obtaining animal datafor an animal selected to have a solution introduced into its circulatory systemin a rinsing process and determining an insertion location based on the animaldata. This method embodiment also includes establishing a fluid conduit froma. reservoir through the insertion location into the circulatory system of theselected animal by inserting a cannula in fluid communication with the reservoirthrough the insertion location. The method further includes activating flowof a solution from the reservoir through the fluid conduit to introduce the solutioninto the circulatory system of the animal.
