Abstract: A portable apparatus for assessing meat quality, comprises: a hand-held instrument comprising a main body having at one end a hollow meat probe for penetrating meat, an optic fibre extending through the main body and terminating at a window at the distal end of the probe. The main body has a probe position sensing device for sensing position as the probe enters and exits the meat. A carrier pack is adapted for mounting on an operator. The pack comprises a fluorimetry unit having a source of ultraviolet radiation, a power source and a microcontroller/processing unit. A user interactive communications device is on the main body and a cable interconnects the main body and the carrier pack. The cable transmits electronic data between the interactive communication device and the microcontroller/processor unit and ultraviolet radiation output and fluorescent light input between the probe window and the fluorimetry unit.
