Ethoxyquin

Ethoxyquin is a quinoline-based aromatic compound. It is an antioxidant and serves as a feed additive with a maximum of 150mg/Kg. In fishmeals it prevents the auto oxidation of fatty acids, i. e. effects an extension of the shelf life.

During storage and transport of fish meals heat development caused by oxidation processes can result in explosions. For this reason the IMSBC Code prescribes the addition of ethoxyquin to reduce the risk of fire during transport of fish meals.

The current data situation on the toxicity of ethoxyquin is unclear. Since harmful effects on human and animal health or environment can not be excluded the European Commission decided in June 2017 to withdraw the authorisation as a feed additive which probably results in a total prohibition of use from January 1, 2021.
