Introduction:The latest inspection results released by the Guangdong Provincial Market Supervision Administration have revealed that multiple popular brands of packaged drinking water were found to contain Pseudomonas aeruginosa, a conditional pathogen that poses a particular threat to individuals with weakened immune systems. This article provides an in-depth analysis of the source of the bacteria, details of the responses from the involved brands, and offers four practical tips for choosing water — from selecting reputable companies and reading labels to examining water quality — to help you avoid potential hygiene risks.
Water accounts for 60% to 70% of the human body, and adults need to consume at least 3 to 5 liters per day to maintain normal metabolism. As public awareness of health grows, the demand for packaged drinking water marketed as “pure” or “mineral” has surged. However, whether these products meet national food safety standards remains a key concern for consumers.
The food inspection bulletins No. 30 to 33 issued recently by the Guangdong Provincial Market Supervision Administration show that drinking water products from well-known brands such as Luhu Mountain, Alps, and Rui Shan Tian Quan were listed as substandard due to the detection of Pseudomonas aeruginosa. This bacterium is a conditional pathogenic microorganism that may cause health risks such as acute intestinal inflammation in vulnerable groups (such as the elderly, young children, or those with chronic illnesses).
Pseudomonas aeruginosa (formerly known as Pseudomonas pyocyanea) is widely present in humid environments. The main reasons for its excessive levels are often related to contamination of the water source or packaging materials. If personnel or tools are not thoroughly disinfected during the production process, or if sterilization procedures do not meet standards, bacterial residues may remain. Regulatory authorities emphasize that qualified drinking water must meet both “sufficient supply” and “hygienic water quality” criteria — it should not only be supplied stably but also be free from pathogenic microorganisms, chemical pollutants, and abnormal sensory characteristics.
In response to the abnormal inspection results, reporters contacted the involved companies to inquire about the handling progress. Meizhou Yuhuagu Mountain Spring Water Co., Ltd. responded that the substandard batch of Luhu Mountain Natural Drinking Spring Water was produced in May 2024, and the initial assessment attributed the issue to improper storage conditions (the batch was stored in a stairwell and the inspection took place on a rainy day). Subsequent internal retests and third-party tests on more than ten batches at the factory and retail stores did not detect any further issues. Rui Shan Tian Quan pointed out that the single case of detected bacteria in the involved metasilicic acid-type natural drinking spring water (produced on May 9, 2024) was likely related to environmental exposure during transportation. A retest by the Meijiang District authorities did not find any recurrence of abnormalities.
How can you ensure the safety of drinking water at home? Regulatory experts offer four practical suggestions: First, “choose the company” — prioritize purchasing products from reputable, licensed brands with a good market reputation; second, “select the vendor” — it is recommended to order through legal distributors or water stations, and for sources of uncertain origin, verify their business qualifications or directly confirm the partnership with the manufacturer; third, “check the label” — look for bottled water with complete outer packaging information (such as water source, production date, shelf life, ingredient list, etc.) and clear labeling; lastly, “observe the water quality” — qualified products should be colorless and transparent, with no unusual odor, impurities, sediments, even coloration, or visible suspended particles.
