Objective To investigate the microbial contamination of prepared beverage in China.Methods According to the principle of random sampling， 3 583 samples of prepared beverage and edible ice were collected from representative restaurants， beverage shops， fast food restaurants and collective school canteenagers in municipalities and autonomous regions of China. The total number of bacteria， coliform bacteria， Staphylococcus aureus and Salmonella were detected by the national standard method.Results Total colonies of 8.42% of the product were greater than 10⁵ CFU/mL， coliforms of 19.32% of the products were greater than 10² MPN/mL. The detection rates of S. aureus and Salmonella were 2.56% and 0.09%， respectively， which were lower than 10² MPN/mL. The contamination in protein drinks was the most serious， the ratios of total colonies over 10⁵ CFU/mL and coliforms over 10² MPN/mL were 21.35% and 32.97%， respectively. From March to May， the sanitary condition of prepared beverages was the worst， and the ratio of total number of colonies greater than 10⁵ CFU/mL was 14.80%. The highest detection rate of S. aureus was 5.24% in restaurants and hotels.Conclusion The food safety status of current prepared beverage is generally good， but related departments should also strengthen the supervision and inspection of the processing place.
