Abstract:

This report describes a rapid polymerase chain reaction (PCR) method to detect duck-derived DNA by using
primers corresponding to the duck COⅢ gene. The method was duck specific, free from interference from lumb DNA (50
mg/kg). Its sensitivity was sufficient to detect as low as 0.1 μg/kg duck-derived materials. It can provide a rapid and accurate
way to identify duck-derived materials adulteration in meat products without interference of mutton DNA.

Key words: duck-derived materials, cytochrome oxidase Ⅲ (COⅢ ) gene, polymerase chain reaction (PCR), detection
