Recently, the Shaanxi Provincial Market Supervision and Administration Bureau organized food safety supervision and sampling of 101 batches of samples of beverages, convenience foods, health foods, edible agricultural products, tea and related products, and alcohol, of which 7 batches of samples were unqualified, and microbial contamination was detected.
Shaanxi Yonghui Supermarket Co., Ltd. Xi'an Taihua North Road Branch sells the nominal Shaanxi Tianye Industry and Trade Co., Ltd. commissioned Xi'an Duobaoduo Halal Food Co., Ltd. to produce lamb steamed buns (instant food), the total number of colonies tested value is 2000000, 1900000, 1700000, 5000000, 1100000 (CFU/g), the standard provisions are n=5, c=2, m=10000, M=100000 (CFU/g).
Shaanxi Keyouduo Trading Co., Ltd. Xi'an Fengcheng 10th Road Branch sells the nominal Xi'an Tongshengsheng Halal Food Co., Ltd. production of Tongshengsheng brand lamb steamed buns, the total number of colonies 480000, 580000, 770000, 1100000, 1600000 (CFU/g), the standard is specified as n =5, c=2, m=10000, M=100000 (CFU/g).
The total number of colonies is an indicative microbiological indicator, which is mainly used to evaluate the cleanliness of food and reflect whether the food meets hygienic requirements during production. The total number of colonies seriously exceeds the standard, which will destroy the nutritional composition of the food, accelerate the spoilage of the food, and make it lose its edible value. The reason for the total number of colonies exceeding the standard may be that the initial number of raw materials used by individual enterprises is high, and the sanitary conditions of the production and processing process are not strictly controlled according to the requirements, or the cleaning and disinfection of packaging containers is not in place, and it may also be related to the lax sealing of product packaging and improper control of storage and transportation conditions.
Guanshan Huoquan Drinking Pure Water produced by Guanshan Huoquan Pure Water Co., Ltd. nominally has a coliform detection value of 0,0,0,2,0 (CFU/mL), and the standard is specified as n=5, c=0, m=0 (CFU/mL); The detection value of Pseudomonas aeruginosa is 7,0,0,0,0 (CFU/250mL), and the standard specifies that n=5, c=0, m=0 (CFU/250mL).
The pure natural drinking water produced by the nominal Baoji Beer beverage factory sold by the Shuiwanjia Bottled Water Distribution Center in Qianyang County has a detection value of 1,0,4,1,6 (CFU/250mL) and the standard is n=5, c=0, m=0 (CFU/250mL).
The other drinking water of Ganquan produced by the nominal Jingyang County Ganquan Pure Water Plant has a detection value of 1,1,0,0,0,2 (CFU/250mL) for Pseudomonas aeruginosa, and the standard is specified as n=5, c=0, m=0 (CFU/250mL).
The nominal Yijianyuan brand Yijianyuan drinking pure water produced by Shaanxi Henghua Food and Beverage Co., Ltd. sold by Sanyuan Yijianyuan Bottled Water Supply Station has a detection value of 3,2,1,0,1 (CFU/250mL) and the standard is n=5, c=0, m=0 (CFU/250mL).

Coliform bacteria are one of the commonly used indicator bacteria for food contamination at home and abroad. Coliform bacteria detected in food indicate a greater likelihood of contamination by pathogenic bacteria. The reason for the excessive coliform bacteria in bottled pure water may be that the processing raw materials and packaging materials of the product are contaminated, or the product is polluted by personnel, tools and other production equipment, the environment, and the product with sterilization process is not completely sterilized.
Pseudomonas aeruginosa is a conditional pathogen that poses a health risk to people with weaker resistance. The reason for the excessive standard of Pseudomonas aeruginosa in bottled drinking water may be improper protection of water sources and pollution of water bodies; some enterprises do not have adequate environmental health supervision, insufficient standardization of operation, and cross-contamination in the production process; in the circulation link, the storage time is long, and the repeated recycling of buckets increases the risk of secondary pollution.
