EFSA assessed a DHA-rich oil from Schizochytrium sp. A2 proposed for infant and follow-on formula. The documentation did not conclusively demonstrate the producer strain’s identity at species level.

Organism identity is central because it connects manufacturing with history of use, toxigenic potential, contaminants and material reproducibility. If that link remains open, apparently robust compositional data lose part of their regulatory meaning.

For ingredient scouting and due diligence, the case supports early checks of strain deposit, genomic methods, culture purity, traceability and consistency between the described organism and industrial process.

The opinion does not classify the entire category of algal oils as unsafe. It states that the information available for the assessed material and uses was insufficient to conclude on safety.

Why it matters

The case shows that microbial identity, traceability and characterisation methods are dossier prerequisites, not details to complete after product testing.

Evidence limit

The absence of a favourable conclusion does not mean that all Schizochytrium oils are unsafe. The issue concerns the assessed material and documentation.
