Increasing demands for high-quality animal protein drives the global milk and meat industry to augment their potential productivity, while reducing carbon footprints and waste excretion. To attain this goal, there has been tremendously progress in animal biotechnology over the past 40 years to produce recombinant proteins and organic nutrients, clones of elite individuals, and genetically modified animals for agricultural and biomedical purposes. Obviously, the efficiency of livestock production has been improved significantly due to advances achieved in animal breeding, management, and nutrition during the past few decades. However, there is still room for improvement in quantity and quality of animal products through the application of modern biotechnology techniques (Azad et al. 2023; Bacanli and Basaran 2019; Herman 2001; Kalorey et al. 2007).

Now a days, antibiotics are widely used in both dairy and beef production enterprises to control pathogens that cause infectious diseases. Such random use of antibiotics may result in the formation of a residual amount of drugs in livestock products, which lead to abnormal functioning of the small intestine, development of allergic reactions, generation of antimicrobial resistance and other side effects. In this respect, the use of antibiotics in animal husbandry and veterinary medicine should be deeply controlled (Mafra et al. 2008; Sartoru et al. 2017; Zeakti et al. 2019).

Obviously, the innovation and progress achieved in the methods developed for rapid detection of foodborne pathogens for the health and wellbeing of mankind are documented. Identification of animal products offered for sale and public consumption is necessary for consumer preference and regulatory surveillance.

Currently, biotechnology provides a wide variety of valuable, quick and effective tests to trace the product origin and authentication in favour of sanitary and health of consumers. Adulteration of animal products, including meat and milk, may be precisely detected using real-time polymerase chain reaction (qPCR). Different molecular genetics techniques are applied at our institution to provides a wide variety of valuable, quick and effective tests to trace the product origin and authentication in favour of sanitary and health of consumers.
