Abstract: Obtaining an early indication of the quality of meat such as defective meat comprising the steps of taking a sample of muscle tissue, disrupting and incubating the sample in order to activate and progress the conversion of glycogen to lactic acid so that the conversion proceeds at a rapid rate by comparison to normal conversion rate in muscle tissue processed and stored normally in meat processing operations and providing an indication of the pH to determine if in range that indicates the meat is defective. A sampling tool (111) usable to sample a muscle tissue having a conical tool head (112) with a leading point (121) to aid insertion into an animal and rearwardly facing cutting edge (123) that takes a sample of tissue when the tool is being withdrawn. A sample removing means (127) having a front convex surface (128) able to force the sample out of a concave base (120) of the tool head (112).
