P. aeruginosa is called Pseudomonas aeruginosa. It is widely distributed in nature and is one of the most common bacteria found in the soil. All kinds of water, air, normal human skin, respiratory tract and intestines have their own existence.
A common pathogenic bacteria in the city of bacteria, belonging to non-fermenting Gram-negative bacilli. The cells are slender and vary in length, sometimes in the form of spheres, arranged in pairs or short chains. A section of the cell has a single flagella, and the activity of the bacteria is observed under a dark field microscope or a phase contrast microscope.
The reference to the water national standard GB19298-2014 and GB8537-2008 clearly stipulates that the Culex green stem cell bacteria should not be detected in every 250ml water sample. Because of its wide distribution in nature, it has added many challenges to packaging water producers. Various over-reporting industries have frequently seen newspapers; generally, the number of patina in products that have just been manufactured is relatively small, which is difficult to detect in sampling inspection due to packaging water consumption. The cycle is longer, and the patina has lower requirements for organic nutrition, and can be propagated to 104 CFU/ml within tens of days. The only way to completely eliminate the quality of the finished product in Tonglu City before filling should be used as an important criterion to measure the disinfection effect of the disinfection process.
How to prevent excessive Pseudomonas aeruginosa in drinking water:
1. Ensure that the water source is clean and hygienic: clean and hygienic water source is the prerequisite for ensuring the quality of bottled water. Therefore, it is necessary to strengthen water source protection and regularly monitor water source.
2, production and processing supervision: to ensure the health and safety of water is the premise, the supervision of processing engineering is the top priority. First of all, to ensure the processing environment (such as air purification), equipment and appliances clean; secondly, the staff’s personal hygiene should be in place; and then strengthen the packaging cleaning and disinfection process, especially the large plastic bucket inner wall suitable for turnover, must be carefully scrubbed After disinfection and cleaning, and prevent strong water flow washing, the Pseudomonas aeruginosa bacteria spread by water mist.
3, regular testing: water is the premise, processing is the key, testing is a guarantee. Regular inspection agencies are selected to check the bottled water regularly to ensure the health and safety of bottled water from a more scientific level.
Control of Pseudomonas aeruginosa when producing pure water:
1. Use a sterile water tank with respirator and spray
2. Use an effective sterilization system (ultraviolet sterilizer or ozone generator)
3. Use a sterilization system (ultraviolet sterilizer or ozone generator) for disinfection before entering the filling
4, pre-wash using high-temperature alkaline washing
5. Add a light inspection box when the filling machine enters the barrel, and use manual detection.
