EFSA initiates re-evaluation of feed additives

Cylactin is a microbial feed additive based on a strain of lactic acid bacteria (Enterococcus faecium), which has had a history of use with both animals and humans. The initial assessment showed that the strain of lactic acid bacteria used in this product is more resistant to kanamycin than most other strains of Enterococcus faecium. Following a thorough review of the data, including the full genome sequence the Panel concluded that the antimicrobial resistance was not acquired; therefore, the risk that the bacteria might transfer kanamycin resistance to other organisms is not a cause for concern.

The Panel concluded that Cylactin is effective as a feed additive used for chickens for fattening and that there is no evidence that its use results in adverse effects for the target animals, human health or the environment.

The European Food Safety Authority’s FEEDAP Panel is re-evaluating all feed additives currently on the market, authorised under the previous regulatory framework, and in line with current EU legislation on feed additives for use in animal nutrition. The aim of the work is to ensure that all feed additives in Europe are re-assessed following the same, up-to-date guidelines taking into account the newest scientific developments.

EFSA has already received more than 30 feed additive applications for re-evaluation. In addition, the FEEDAP Panel is continuing to assess new additives submitted for authorisation in the EU, or new uses for additives already authorised. To date EFSA has evaluated more than 200 feed additive applications.
