BACTOCELL authorized in Europe as a technological additive

First lactic acid bacteria to receive authorization related to the hygiene of liquid feed

Our unique lactic acid bacteria strain Pediococcus acidilactici CNCM I-4622 (BACTOCELL) has been authorized in the European Union as a technological feed additive in the functional group of acidity regulators and hygiene condition enhancers. The authorization is for use in all animal species (REGULATION (EU) 2023/53).1 BACTOCELL was already recognized by the European Food Safety Authority (EFSA) for its safety and potential to reduce pH and limit the growth of coliform bacteria in liquid feeds.

The authorization covers the application of the lactic bacteria in mash compound feeds and/or solid feed materials used for the preparation of liquid feeds at a minimum inclusion level of 1×109 (colony-forming units) CFU/kg feed. This is the first lactic acid bacteria to receive such authorization related to the hygiene of liquid feed.

In Europe, a liquid feed is particularly popular for swine in countries including Denmark and Sweden, where more than 60% of finishers — as well as the majority of sows — are fed liquid feed.2 Ensuring the sanitary quality of liquid feed and the feeding system itself is a key priority for producers.

David Saornil, Product Manager for Swine Application at Lallemand Animal Nutrition, commented:

“We are very pleased with this new authorization that validates the benefits of BACTOCELL as a solution to improve liquid feed quality in sows, fattening pigs, and piglets.

BACTOCELL was already recognized for its probiotic benefits on gut health. We continue to document our benefits to producers and the industry as a whole.”
