Cronobacter spp. in commercially available dried food in Japan.
A total of 140 samples of dried food sold in Japan were surveyed and tested for the presence of viable bacteria, distribution of coliform bacteria, and contamination with Cronobacter spp. The samples were purchased from retail stores in Tokyo and Kanagawa Prefecture. Out of the 140 samples tested, viable bacteria were found in 135 samples and coliform bacteria were found in 23 samples. Qualitative and quantitative testing revealed the presence of Cronobacter spp. in 35 (25.0%) and 11 samples (7.9%), respectively. The most commonly found Cronobacter species were C. sakazakii, with the next most common, in order, being C. muytjensii and C. turicensis. The actual numbers of Cronobacter species in the tested dried foods were low, but the widespread contamination particularly in dried herbs and vegetables was confirmed.
