The use of copper compounds in water for drinking is considered unsafe for ovine and certain breeds of dogs and cats; for all other animal species/categories the simultaneous application of copper compounds via feed and water for drinking should be avoided. No concerns for consumer safety are expected from the use of the copper compounds under application in animal nutrition when used up to the maximum EU …
