  • “Lactobacillus acidophilus” Probiotic for Cats and Dogs: benefits attested by the EC 1


What is stated in the European Commission Regulation authorising use of “Lactobacillus acidophilus (CECT 4529)” as a feed additive for cats and dogs? What are the benefits for the health of animals? In this article, we will explore them together.

On 17 October 2018, the European Commission authorised Centro Sperimentale del Latte (a company of the Sacco System group) to use Lactobacillus acidophilus (CECT 4529) as a probiotic feed additive for cats and dogs.

The authorisation, which is available to read in full here, is based on two previous authorisations issued by the European Commission for use of the preparation of Lactobacillus acidophilus (CECT 4529) as a feed additive for laying hens (Implementing Regulation EU 2015/38) and chickens for fattening (Implementing Regulation EU 2017/2275).

On 19 April 2018, the European Food Safety Authority issued an opinion concluding that “under the proposed conditions of use, the preparation of Lactobacillus acidophilus (CECT 4529) does not have an adverse effect on animal health, human health and the environment. The additive has the potential to improve the stool consistency of cats and dogs.

What does the EC Regulation establish for the use of Lactobacillus acidophilus (CECT 4529)?
