Abstract
From meat retails in Mosul province, forty-five meat samples of local ovine and bovine (23 bovine samples and 22 ovine samples) were collected. The period of collection was during November 2010 to May 2011, by means of multistage random sampling for detection of streptomycin residues. Enzyme linked immunosorbent assay (ELISA) was used for detection of streptomycin residues. The results revealed that eleven ovine meat samples (50%) were positive to streptomycin residue, with a mean value 35.06 µg kg-1, while 14 bovine meat samples (60.86%) were positive to residual streptomycin with a mean value 59.56 µg kg-1. From the results, it is clear that all tested meat samples (ovine and bovine) were safe enough for human consumption.
Highlights
Meat is one of the most important constituents of the human diet as it provides protein, energy, vitamins and minerals [1]
Half of the ovine samples were negative (50%) for STR residues, while (39.13%) was negative for bovine samples
The remaining (50%) of ovine samples were positive (n=11) with concentration ranged between 26.12 to 50 μg kg-1
Summary
Meat is one of the most important constituents of the human diet as it provides protein, energy, vitamins and minerals [1]. Due to the demand for increasing meat production, several agents employed for animal treatment and for growth promotion. These include various types of antibiotics, sulfonamides and synthetic as well as natural anabolic agents, which could be a source of health hazards [2]. The use of veterinary drugs for food producing animals can affect the public health and international trade of food products, because of the presence of residues of the drugs, or their metabolites in edible products. Streptomycin (STR), produced by Streptomyces griseus, is an aminoglycoside antibiotic, which shows activity against aerobic gram – negative bacteria and is widely used in treatment of infectious diseases in farm animals [4]. STR residues reported to be present in meat, liver, kidney, milk and other food commodities [5]
