The tetracyclines are a group of closely related bacteriostatic antibiotics with similar antibacterial spectra. Tetracyclines are used extensively in veterinary medicine and their use in food producing animals could result in potentially harmful concentrations in tissue and organs.Regulatory authorities have specified maximum residual levels (MRLs), or tolerances, for tetracyclines, which are considered to represent safe levels for human consumption.
