    2023年3月2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）研究小组就噬菌体PCM F/00069、PCM F/00070、PCM F/00071和PCM F/00097作为所有禽类饲料添加剂的安全性和有效性发表科学意见。

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 a product consisting of four bacteriophages infecting Salmonella enterica ser. Gallinarum B/00111, intended to be used as a zootechnical additive (functional group: other zootechnical additives) for all avian species. The additive (tradename Bafasal®) is not currently authorised in the European Union. Bafasal®is intended to be used in water for drinking and liquid complementary feed to guarantee a minimum daily dose of 2 × 10⁶PFU/bird, to reduce the Salmonella spp. contamination of poultry carcasses and load in the environment, and to improve the zootechnical performance of the treated animals. In a previous opinion, the FEEDAP Panel could not conclude on the additive"s potential to be irritant or a dermal sensitiser, or on its efficacy for any avian species due to insufficient data. The applicant provided supplementary information to address these data gaps. The new data showed that Bafasal®is not a skin or eye irritant. No conclusions could be drawn on its skin sensitisation potential. The Panel was not in the position to conclude on the efficacy of Bafasal®to improve the zootechnical performance of the target species based on the available data. The additive showed the potential to decrease the counts of two strains of Salmonella Enteritidis in boots swabs and caecal digesta of chickens for fattening. No conclusions could be drawn on the capacity of Bafasal®to reduce the contamination of other Salmonella enterica strains, serovars or other species of Salmonella. The potential of Bafasal®to reduce the Salmonella spp. contamination poultry carcasses and/or the environment is limited. The FEEDAP Panel recommended a post-market monitoring plan to address the potential selection and spread of resistant variants of Salmonella to Bafasal®.
