2023年6月16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）研究小组就肉豆蔻精油（nutmeg oil）作为所有动物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。由于该添加剂被认为可以给食物调味，而且它在饲料中的功能也是一样的，因此认为没有必要进一步证明其功效。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 an essential oil from the seeds of Myristica fragrans Houtt. (nutmeg oil), when used as a sensory additive in feed and water for drinking for all animal species. The additive contains myristicin (up to 12%), safrole (2.30%), elemicin (0.40%) and methyleugenol (0.33%). For long-living and reproductive animals, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) considered of low concern the use of the additive in complete feed at 0.2 mg/kg for laying hens and rabbits, 0.3 mg/kg for sows and dairy cows, 0.5 mg/kg for sheep/goats, horses and cats, 0.6 mg/kg for dogs and 2.5 mg/kg for ornamental fish. For short-living animals, the Panel had no safety concern when the additive is used at the maximum proposed use level of 10 mg/kg for veal calves, cattle for fattening, sheep/goats, horses for meat production, and salmon and for the other species, at 3.3 mg/kg for turkeys for fattening, 2.8 mg/kg chickens for fattening, 5.0 mg/kg for piglets, 6.0 mg/kg for pigs for fattening and 4.4 mg/kg for rabbits for meat production. These conclusions were extrapolated to other physiologically related species. For any other species, the additive was considered of low concern at 0.2 mg/kg. The use of nutmeg oil in animal feed was expected to be of no concern for consumers and the environment. The additive should be considered as irritant to skin and eyes and as a skin and respiratory sensitiser. based on the presence of safrole, nutmeg oil is classified as carcinogen (category 1B) and handled accordingly. Since nutmeg oil was recognised to flavour food and its function in feed would be the same, no further demonstration of efficacy was considered necessary.
