Abstract
AbstractThe present study quantitatively analyzed the occurrence of antibiotic residues in 524 milk samples (492 raw milk samples from dairy farms and 32 commercial milk samples) from Punjab, India using high‐performance liquid chromatography (HPLC). Tetracyclines, sulphonamides, fluoroquinolones (commonly used in veterinary practice in Punjab), and chloramphenicol (banned in food animals in India) were targeted and analyzed using multiresidue HPLC method. Out of 492 dairy farms milk samples, 78 (16%) were found to be positive for antibiotic residues with 20 (4%) exceeded the maximum residue limits (MRLs). Among 32 commercial milk samples, 4 (12.5%) were positive for antibiotic residues with one (3.1%) sample violated the MRL. Assessment of human health risks revealed that the current levels of antibiotic residues in milk pose no significant toxicological effects on the health of consumers. However, the results highlighted an immediate need of effective strategies for prevention of nonprudent use of antibiotics in veterinary practice for safeguarding consumer's health.
