Authentication of traditional meat products (Haleem) sold in India: a first report confirming species mislabelling

Traditional meat products like Haleem play a pivotal role in the culinary landscapes of Indian consumers, along with high economic value and business potential. Due to anticipated gains associated with adulterating ‘Haleem’ and constant evasion from regulatory oversight, the susceptibility to adulteration has substantially increased. Furthermore, no reports/surveillance regarding their labelling compliance has been reported. Hence, we conducted a 2-year surveillance using 100 samples collected from Hyderabad, India, using the Chipron™ DNA macroarray analysis technique. The method was validated for sensitivity (1%), specificity, and with proficiency test samples. Following this, the surveillance samples (beef, chicken, and mutton Haleem) were tested. The surveillance revealed an alarming adulteration of 46% of the samples, with different proportions of adulterant species. Adulteration of unconventional meat like camel meat was also found. These concerning results necessitate the requirement of stricter and constant regulatory surveillance to safeguard consumer trust and preserve the authenticity of traditional meat products.
