The objectives of this study were to investigate the microbiological safety of various foods intended for consumption by infants and babies.
The incidence of Cronobacter spp. and Enterobacteriaceae from powdered infant formula (PIF, n = 75) and baby soy milk (n = 10) was examined. Additionally, aerobic plate count, coliforms and the prevalence of foodborne pathogens were investigated in 230 samples from a variety of infant and baby foods, including cereal-based follow-up formulas (FUF), liquid FUF and other infant foods. High APCs were observed in nutrient supplements and cereal-based FUF. Coliforms were found in 6 (2·6%) products, and Cronobacter spp. was isolated in 10 (4·4%) samples, including four PIF and six cereal-based FUF. Bacillus cereus was detected in 48 (20·9%) samples: cereal-based FUF items (23·0%), rice soups (20·6%), honey samples (40·0%), biscuits (40·0%) and liquid FUF (7·4%).
New safety criteria, along with hygienic control measures and consumer education strategies, are essential to improve the microbiological safety of infant or baby foods.
This study provides comprehensive information about the prevalence and level of contamination of infant and baby food products by Cronobacter spp. and other major foodborne pathogens.
本研究旨在调查各种婴幼儿食品的微生物安全性。
检测了粉状婴儿配方食品（PIF，n=75）和婴儿豆浆（n=10）中克罗诺杆菌属和肠杆菌科的发生率。此外，还对 230 份来自各种婴幼儿食品的样品进行了需氧平板计数、大肠菌群和食源性病原体的流行情况调查，这些食品包括以谷物为基础的后续配方食品（FUF）、液体 FUF 和其他婴儿食品。营养补充剂和以谷物为基础的 FUF 中观察到高 APCs。有 6 种（2.6%）产品检出大肠菌群，10 种（4.4%）样品分离出克罗诺杆菌属，包括 4 种 PIF 和 6 种以谷物为基础的 FUF。48 种（20.9%）样品中检出蜡样芽胞杆菌：以谷物为基础的 FUF 产品（23.0%）、米粥（20.6%）、蜂蜜样品（40.0%）、饼干（40.0%）和液体 FUF（7.4%）。
新的安全标准，以及卫生控制措施和消费者教育策略，对于提高婴幼儿食品的微生物安全性至关重要。
本研究提供了关于婴幼儿食品中克罗诺杆菌属和其他主要食源性病原体的流行情况和污染水平的综合信息。
