To determine the prevalence of Cronobacter spp. (Enterobacter sakazakii) in follow-on formula powders commercially available in European countries.
A total of 470 samples comprising 31 different products from 18 brand names belonging to seven companies were tested for the presence of Cronobacter species. No milk- or soy-based infant formula powders were found to contain Cronobacter species. However, two cereal-based infant drinks were positive for Cronobacter sakazakii. A review of the published cases spanning the past 48 years did not reveal any fatalities attributable to Cronobacter spp. in children over 3 months.
The low incidence of Cronobacter in infant powdered drinks, the lack of fatal Cronobacter infections in infants greater than 3 months and the low incidence of Cronobacter-related reported illness in this age group indicated that ingestion of these products presents a low risk for the intended consumers.
The risk posed to neonates from the consumption of infant formula contaminated with Cronobacter is clear. Risks associated with powdered follow-on formulae intended for consumption by older infants is now under consideration by the World Health Organization. Our data contributes to the body of knowledge available for the assessment of the risk to consumers from these food products.
确定欧洲国家市售后续配方奶粉中阪崎肠杆菌属（阪崎肠杆菌）的流行情况。
对来自7家公司的18个品牌的31种不同产品共470份样品进行了阪崎肠杆菌属检测。未发现以牛奶或大豆为基础的婴儿配方奶粉含有阪崎肠杆菌属。然而，两种以谷物为基础的婴儿饮品阪崎肠杆菌检测呈阳性。回顾过去48年发表的病例，未发现3个月以上儿童因阪崎肠杆菌属导致的死亡病例。
婴儿粉末饮料中阪崎肠杆菌的低发生率、3个月以上婴儿中缺乏致命的阪崎肠杆菌感染以及该年龄组中阪崎肠杆菌相关报告疾病的低发生率表明，摄入这些产品对目标消费者的风险较低。
食用受阪崎肠杆菌污染的婴儿配方奶粉对新生儿造成的风险是明确的。世界卫生组织目前正在考虑与较大婴儿食用的后续配方奶粉相关的风险。我们的数据有助于为评估这些食品对消费者的风险提供可用的知识体系。
