2021年7月29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）研究小组就尼卡巴嗪（nicarbazin ）作为育肥火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，在火鸡的完整饲料中使用尼卡巴嗪不会对陆地和水生环境以及沉积物造成风险。尼卡巴嗪在环境中的生物累积潜力很低。部分原文报道如下：
Following a request from the European Commission, the Panel on Additives and Products or substances used in Animal Feed (FEEDAP Panel) was asked to deliver a scientific opinion on the safety for the environment of the coccidiostat Coxar® (nicarbazin) when used in feed for turkeys for fattening. In previous assessments, the FEEDAP Panel could not conclude on the safety of Coxar® for the environment due to concerns on 4,40-dinitrocarbanilide (DNC, one of the moieties of nicarbazin). On the basis of the new data provided, the FEEDAP Panel updates its previous conclusions on the safety of Coxar® for the environment as follows: The use of nicarbazin from Coxar® in complete feed for turkeys does not pose a risk for the terrestrial and aquatic compartment and in sediment. No concern for groundwater is expected. The bioaccumulation potential of nicarbazin in the environment is low.
