Safety of oil from Schizochytrium limacinum (strain ATCC‐20889) for use in infant and follow‐on formula as a novel food pursuant to Regulation (EU) 2015/2283

EFSA Journal, Volume 23, Issue 1, January 2025.
Abstract Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on the safety of an oil derived from the microalga Schizochytrium sp. (strain ATCC‐20889) as a novel food (NF) pursuant to Regulation (EU) 2015/2283.

Scientific opinion on marine biotoxins in shellfish in the Republic of Croatia

Food Risk Assess Europe, Volume 2, Issue 2, April 2024.
Summary Marine biotoxins are thermostable, mostly non‐protein molecules with different chemical components. According to solubility, they are divided into water‐soluble (hydrophilic) and fat‐soluble (lipophilic). The regulations of the EU and the Republic of Croatia regarding the maximum limits (ML) in live shellfish cover several groups: azaspiracids (

Clarification of the C-35 Stereochemistries of Dinophysistoxin-1 and Dinophysistoxin-2 and Its Consequences for Binding to Protein Phosphatase

, 2016
Okadaic acid analogues are well known as protein phosphatase inhibitors and occur naturally in marine shellfish feeding on dinoflagellates of the genus Dinophysis, leading to diarrhetic shellfish poisoning of shellfish consumers. Knowledge of the correct
