Technical Abstract: Presented is the development of a solid phase extraction (SPE) procedure and a liquid chromatography-mass spectrometry (LC-MS/MS) method for quantifying tylosin in cattle waste samples. Tylosin is a macrolide antibiotic found naturally as a fermentation product of Streptomyces fradiae and is mainly used in promoting growth and treating infections in animals. Tylosin acts by inhibiting protein synthesis in bacteria. In cattle, tylosin is used for treating bovine respiratory complex, foot-rot and calf diphtheria, while in swine it is used to treat swine arthritis, swine pneumonia and swine erysipelas. The products from antibiotic treated livestock, such as milk, meat (chicken, pork, cattle beef), excreta and manure possess residual antibiotics and resistance genes (ARG’s) which are consequently passed to humans. Each year 2 million people suffer and about 23,000 die from infections caused by bacteria that are resistant to antibiotics. New drugs are coming into the market almost daily, but developing renewed resistance is a real problem. One of the reasons for the development of antibiotic resistance is the overuse of antibiotics such as tylosin in animal feed. Furthermore, tylosin resistant genes are also being measured in these waste samples by PCR (Polymerase Chain Reaction).
