The European Union evaluates the safety and efficacy of a betaine copper complex as an additive for all animal feed

On 22 February 2023, according to the European Union Food Safety Authority (EFSA), at the request of the European Commission, The EU Study Group on Additives and Products for Animal Feed (FEEDAP) has issued a scientific opinion on the safety and efficacy of a betaine copper complex (copper(II)-betaine complex) as an additive for all animal feed.

Some of the original reports are as follows:

Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP Panel) was asked to deliver a scientific opinion on the safety and efficacy of a copper(II)-betaine complex as nutritional feed additive for all animal species. based on the results of a tolerance study carried out in chicken, the FEEDAP Panel concluded that the additive is safe for chickens for fattening when used up to the current maximum authorised levels of copper in feed; this conclusion was extrapolated to all animal species and categories at the respective maximum copper levels in complete feed authorised in the European Union. The FEEDAP Panel concluded that the use of the copper(II)-betaine complex in animal nutrition at the maximum copper levels authorised for the animal species poses no concern to the safety of consumers. Regarding the safety for the environment, the use of the additive in feed for terrestrial animals and land-based aquaculture is considered safe under proposed conditions of use. The data available do not allow the conclusion to be made on the safety of the additive for marine sediment when it is used in sea cages. The additive is not a skin irritant, but it is an irritant to the eyes. Due to the traces of nickel, the additive is considered to be a respiratory and skin sensitiser. The Panel could not conclude on the efficacy of the product.
