Calcium EDTA

Calcium EDTA (CaEDTA) is an injectable chelating agent which is the preferred initial chelator for treatment of lead and zinc poisoning in poultry. CaEDTA must be administered parenterally (IM, IV, sometimes SC) because if given orally it actually enhances the absorption of metal from the gastrointestinal tract.

Note: CaEDTA chelates important necessary minerals from the bird's body, such as zinc. Any birds with existing neurological signs will initially worsen after receiving treatment with CaEDTA.
