How to prevent the production of Pseudomonas aeruginosa in bottled water

The main reasons for exceeding the limit of Pseudomonas aeruginosa in bucket or bottled water are:

1. The raw material water has been infected;

2. The hygiene control during the production and processing process is not strict;

3. Employees do not meet hygiene standards;

4. Incomplete cleaning and disinfection of packaging materials.


1. Starting from the source, ensure the safety of the water source. Manufacturers should regularly test the water source to ensure that the water quality meets the standards.

2. For polluted water sources, effective treatment measures should be taken, such as deep filtration, ozone disinfection, etc., to remove pollutants.

3. Strengthen hygiene management during the production process.

4. Strengthen employee hygiene training, increase the importance of hygiene management among employees, and ensure effective control of hygiene conditions during the production process.

5. Cleaning and ozone disinfection of packaging materials such as barrels, bottles, and caps during the production process

6. Regular microbial testing is an important means to ensure disinfection effectiveness. Packaging drinking water plants should regularly conduct microbiological testing on all aspects of the production process, including water sources, production equipment, packaging materials, finished products, etc.
