2022年8月11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）研究小组就长双歧杆菌CNCM I-5642 (PP102I)作为猫和狗饲料添加剂的安全性和有效性发表科学意见。
经过评估，专家小组认为该添加剂对目标物种和环境是安全的，由于缺乏数据，无法就添加剂对皮肤/眼睛的刺激性得出结论，但它应被视为皮肤和呼吸道致敏物。评估小组也无法就添加剂对目标物种的功效得出结论。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) was asked to deliver a scientific opinion on the safety and efficacy of Bifidobacterium longum CNCM I-5642 (PP102I) when used as a feed additive for cats and dogs. The product under assessment consists of viable cells of a strain of B. longum, a species considered suitable for the qualified presumption of safety (QPS) approach to safety assessment. The strain was unambiguously identified as B. longum and was shown not to harbour antimicrobial resistance determinants for antibiotics of human and veterinary importance, thus meeting the QPS requirements. Following the QPS approach to safety assessment and since no concerns are expected from maltodextrin, the other component of the additive, PP102I was considered safe for the target species and the environment. Owing to the lack of data, no conclusions could be drawn on the skin/eye irritancy potential of PP102I. However, it should be considered a skin and respiratory sensitiser. The Panel was not in the position to conclude on the efficacy of PP102I for the target species.
