2020年5月27日，欧盟食品安全局（EFSA）发布关于甲酸钙（Calcium formate）和甲酸钠（Sodium formate）作为所有动物物种饲料添加剂有效性的评估结果。
经过评估，专家小组认为甲酸钙和甲酸钠在所有动物物种饲料中作为防腐剂可能有效。由于缺乏数据，评估小组无法就甲酸钠在饮用水中使用该添加剂的功效做出结论。部分原文报道如下：
In 2015, the EFSA Panel on Additives and Products or Substances used in Animal Feed （FEEDAP ） issued an opinion on the safety and efficacy of ammonium, calcium and sodium formate when used as a technological additive （preservative） for all animal species. Sodium formate was considered safe for all animal species at a maximum concentration of 10,000 mg formic acid equivalents/kg complete feed （with the exception of pigs, for which a maximum concentration of 12,000 mg formic acid equivalents/kg complete feed was considered safe）。
In 2014, the EFSA Panel on Additives and Products or Substances used in Animal Feed （FEEDAP ） issued an opinion on the safety and efficacy of calcium formate when used as a technological additive （preservative） for all animal species. Calcium formate was considered safe for all animal species at a maximum concentration of 10,000 mg formic acid equivalents/kg complete.
