2023年12月7日，据欧盟食品安全局（EFSA）消息，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就苯甲酸（benzoic acid）作为断奶仔猪和育肥猪饲料添加剂的安全性和有效性发表科学意见。
经过评估，专家小组认为在建议的使用条件下该添加剂对消费者和环境是安全的，其作为断奶仔猪和育肥猪的动物技术饲料添加剂是有效的。部分原文报道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of benzoic acid (Kalama®) as a zootechnical feed additive for weaned piglets at a level of 5000 mg/kg complete feed and for pigs for fattening at a minimum content of 5000 mg/kg and a maximum content of 10,000 mg/kg complete feed. The FEEDAP Panel concluded that benzoic acid is safe for weaned piglets at 5000 mg/kg complete feed and for pigs for fattening at 10,000 mg/kg complete feed. The Panel considered the use of benzoic acid under the proposed conditions of use to be of no concern for consumer safety and the environment. Benzoic acid poses a risk by inhalation, it is irritant to skin and corrosive to eyes, but no conclusions can be drawn on dermal sensitisation. The additive, benzoic acid, is efficacious as a zootechnical feed additive for weaned piglets and for pigs for fattening at the proposed conditions of use.
