A preliminary trial using multi-target polymerase chain reaction (multiplex PCR) and restriction fragment length polymorphism (PCR-RFLP) on the same feedstuffs to detect tissues of animal origin.

A preliminary study using multi-target polymerase chain reaction (multiplex PCR) and restriction fragment length polymorphism (PCR-RFLP) was done on the same feedstuffs to detect animal tissues. The results of the two methods differ somewhat: PCR-RFLP did not detect any signal in any sample, but multiplex PCR detected a signal in one sample. These findings could be a basis for further investigations.
