2021年6月3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）研究小組就二甲酸鉀（potassium diformate）作為斷奶仔豬和育肥豬飼料添加劑的安全性和有效性發(fā)表科學意見。

　　經過評估，專家小組認為該添加劑在斷奶仔豬和育肥豬的飼料中作為酸度調節(jié)劑是有效的，最低建議濃度為6000mg/kg全價飼料。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 potassium diformate (Formi? LHS) as a technological feed additive for piglets (weaned) and pigs for fattening. The FEEDAP Panel co ncluded that potassium diformate is safe for weaned piglets and for pigs for fattening at the level of 6,000 mg/kg complete feed, with no margin of safety. The use of potassium diformate in weaned piglets and pigs for fattening nutrition under the co nditions of use proposed is of no co ncern for co nsumer safety. Potassium diformate does not raise co ncern regarding the effects on respiratory system and the skin but is an eye irritant. The use of potassium diformate as a feed additive is co nsidered safe for the environment. The additive is co nsidered to be efficacious as acidity regulator in feedingstuffs for weaned piglets and pigs for fattening at the minimum proposed co ncentration of 6,000 mg/kg complete feed.
