ABSTRACT This study compared bacterial counts and composition in plastic‐bottled green tea beverages immediately after direct drinking and after storage at 37°C for 1 day. Immediately after drinking, (1.9 ± 1.6) × 10 3 and (4.5 ± 3.9) × 10 3 colony forming units (CFU)/mL were recovered from standard green tea and strong green tea, respectively. After 1 day of storage, (1.3 ± 1.5) × 10 4 and (1.6 ± 3.1) × 10 3 CFU/mL were recovered from standard green tea and strong green tea, respectively. Following storage, Lacticaseibacillus spp., Streptococcus , and Veillonella were isolated from both beverages.
