A fluid-operated apparatus for injecting seasoning solutions into meat having a reciprocable head with spaced, independently force-limited needle elements disposed over a conveyor belt for injecting the meat as it is successively positioned by longitudinal and lateral movement of the conveyor belt. The needle elements have individual poppet valves actuated by needle penetration into the meat. The needles are pushed back into the head when bone or cartilage is encountered and a predetermined force is exceeded, thereby protecting them from damage.
