About Tetracyclines (oxytetracycline, chlortetracycline, doxycycline)
- What they are: broad-spectrum antibiotics heavily used in SA cattle, pigs, and poultry.
- Food safety: EU/Codex MRL in milk is 100 µg/kg; higher limits apply to meat/muscle. Carry-over from treated animals causes batch rejection.
- Starter cultures: tetracyclines inhibit the lactic-acid bacteria used in fermented dairy products.
- Typical samples: raw milk, meat/muscle tissue, kidney (highest residue load), eggs.
- Who cares in SA: dairy processors, abattoirs (meat residue monitoring), poultry producers.
β-lactam antibiotics and tetracyclines are natural or artificial antibiotics widely used in animal or human clinical practice. Side effects include severe allergic reactions. Maximum Residue Levels (MRLs) have been established for these two drug classes in the USA, EU, Japan, China and many other countries. The Beta-Lactams & Tetracyclines BT Combo Test Kit is validated by ILVO.
