Implication

Collaborative ring trial validates real-time PCR methods to authenticate dairy composition, indicating strong food safety implications.

Key Points

This research aims to validate real-time PCR methods targeting mitochondrial DNA for dairy product authentication.
Collaborative ring trial involving 15 laboratories
Utilized 4 real-time PCR assays targeting cattle, sheep, goat, and total mammals
Analysis of 50 dairy samples including milk, yoghurt, and cheeses
Calibration using milk-based reference samples to minimize bias
All PCR assays showed high specificity and sensitivity with no false positives or negatives
Quantitative analysis demonstrated good precision across laboratories
Cattle DNA proportions were consistently underestimated but improved with calibration
Duplex PCR formats matched performance of singleplex assays, reducing time and reagent use
Methods effectively differentiate between adulteration and incidental contamination
