2023年12月7日，據歐盟食品安全局（EFSA）消息，應歐盟委員會要求，歐盟動物飼料添加劑和產品（FEEDAP）研究小組就苯甲酸（benzoic acid）作為斷奶仔豬和育肥豬飼料添加劑的安全性和有效性發表科學意見。

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，其作為斷奶仔豬和育肥豬的動物技術飼料添加劑是有效的。部分原文報道如下：

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.
