Is it true that DNA testing is used to authenticate expensive foods like caviar and fine wine?

Yes, it true that DNA testing is used to authenticate expensive foods like caviar and fine wine. DNA testing has become a useful instrument to assess the safety, quality and integrity of the food chain. It also has numerous applications including the identification of allergenic material, the detection of adulteration (e.g. species replacement as a result of commercial fraud), and the identification of microbes that cause food related diseases.

Also, DNA testing is used in different contexts by researchers, food business operators, and public regulatory authorities. The latter may use this methodology to specifically assess the safety and authenticity of foodstuffs, and uncover any breaches of governmental labeling legislation.

Plus, DNA test markers that are used for the identification, characterization, and trace ability of food components help improve the transparency of food production systems, which aid honest producers in the protection of their food products.
