Antibiotics are heavily used for animal treatment, growth enhancer and protection from disease. The residues of antibiotics are related to antibiotic resistance which is the biggest threats to global health, food security and development today. The aim of this study was to investigate the presence of antibiotic residues in available red meat in the Sultanate of Oman.
The extraction was done using QuEChERS method by Aglient and 11 standards were used. The extract was analyzed using The Aglient 6460 LC-MS/MS.
The results showed that investigated Omani goat muscle and liver were free of antibiotics as latter they used as blank sample. All investigated Somali goat samples didn't contain Tetracycline, Amoxicillin, Ceftiofur, Oxacillin, Deoxytetracline, Tylosin and Phenoxymethylpenicillin. Only two samples had Tilmicosin with value of 18-32.2 μl/kg which was that was lower than maxiumam residual limit (MRL). Around 48% of total somali goat samples contained Oxytetracycline (OXY) and Chlorotetracycline (CTC) with value lower than MRL. However, two samples had values of CTC and OXY exceeding the MRL. Ciprofloxacin and Enrofloxacine were detected in 9 samples exceeding the MRL. The finding of this study showed unsafe food source supply to Oman as detection of antibiotic residues in meat.
