通过评定，权威专家工作组觉得在提议的应用标准时该添加物对顾客和条件是可靠的。有关海藻酸钠对总体目标外来物种的安全系数或其在精饲料中做为增粘剂或胶凝剂的作用，并未下结论。一部分全文报导如下所示：

　　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 (functional groups: thickeners and gelling agents). Sodium alginate is intended to be used in feedingstuffs for all animal species at a proposed minimum concentration of 2,000 mg/kg feed and a maximum concentration 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 considered 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 considered safe for the consumers and the environment. No conclusion 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.
