經過評估，專家小組認為在建議的使用條件下該添加劑對消費者和環境是安全的。關於海藻酸鈉對目標物種的安全性或其在飼料中作為增稠劑或膠凝劑的功效，尚未得出結論。部分原文報道如下：

 

　　Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of sodium alginate for all animal species. The additive is intended to be used as a technological additive (functio nal groups: thickeners and gelling agents). Sodium alginate is intended to be used in feedingstuffs for all animal species at a proposed minimum co ncentration of 2,000 mg/kg feed and a maximum co ncentration of to 30,000 mg/kg feed. The data provided for the composition of the additive does not allow a proper assessment of the product consistency, purity and physico-chemical properties. Sodium alginate is not irritant to skin but should be co nsidered irritant to eyes, a skin and respiratory sensitiser and hazardous by inhalation. Sodium alginate is a high-molecular-weight polymer naturally occurring in brown algae. The use of sodium alginate in animal nutrition is co nsidered safe for the co nsumers and the environment. No co nclusion could be drawn on the safety of sodium alginate for the target species or on its efficacy as a thickener or gelling agent in feed.
