2023年5月5日，据欧盟食品安全局（EFSA）消息，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就地克珠利（diclazuril）作为蛋鸡和野鸡饲料添加剂的环境安全性发表科学意见。
经过评估，专家小组得出结论，当地克珠利在拟定的使用条件下(在酸性和非酸性土壤中)用于产蛋鸡和野鸡时，预计不会对陆地部分和沉积物产生风险。无论是酸性土壤还是非酸性土壤，都不会对地下水产生影响。由于缺乏数据，无法对水生环境得出结论。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 for the environment of diclazuril (Coxiril®) as a coccidiostat feed additive for chickens reared for laying and pheasants. In its previous assessments, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) could not reach a final conclusion on the risk resulting from the use of diclazuril in acid soil from Coxiril®. On the basis of the new data provided, the FEEDAP Panel updates the previous conclusions as follows: no risk is expected for the terrestrial compartment and for sediment when diclazuril is used in chickens reared for laying and to pheasants at the proposed condition of use (in both acidic and non-acidic soils). No concern for groundwater is expected for both acidic and non-acidic soils. Due to the lack of data, no conclusions can be drawn for the aquatic compartment. Diclazuril does not have the potential for bioaccumulation; therefore, a risk of secondary poisoning is unlikely.
