- Inconsistent: DNA of some declared and expected species not detected, likely due to processing effects causing DNA damage. Additional common species still present
- Inconclusive: neither expected nor alternative species’ DNA detected, consistent with highly damaged DNA, a challenge also noted in human foods such as canned tuna or corned beef
Study insights
This study demonstrates the value of NGS as a tool for pet food authentication, capable of detecting even trace ingredients and uncovering mislabeling or adulteration risks. While DNA degradation limits detection in highly processed products, combining NGS with complementary methods like digital PCR and mass spectrometry strengthens the overall verification process. As novel ingredients, such as insect proteins, become mainstream, continued expansion of genomic reference databases will be vital in improving the resolution and reliability of pet food authentication strategies.
The study highlights the importance of accurate product labeling in a growing and diverse pet food market, where evolving consumer demands and complex formulations make ingredient authentication increasingly critical.
