Infection causing super bacteria: Pseudomonas aeruginosa

The multi-resistant spoilage bacteria

Pseudomonas aeruginosa is a multi-resistant bacteria known for its immunity against antibiotics and other agents. Infections caused by this bacteria can affect the respiratory tract, blood, ears, or even the heart in people who are already ill or have a weakened immune system. Pseudomonas is often found in hospitals, but the livestock, chemical and food industry also highly struggle with this bacteria. Pseudomonas aeruginosa is most commonly present in the water. As a manufacturer you may encounter this bacteria because of incomplete disinfection or cross-contamination of process water, cooling tanks, or pipes since Pseudomonas aeruginosa is a critical part of the biofilm forming process.

Pseudomonas in the food industry

In the food industry, Pseudomonas aeruginosa is often present in biofilm that forms in areas where water stagnates. It produces enzymes resistant to high temperatures and it can usually be detected during the quality control check of your end products. The bacteria can decay meat or spoil eggs and milk therefore causing off-flavors in processed (dairy) products giving it strong medicinal or bandage taste. However, this can be prevented with a continuous process water disinfection to control the biofilm forming process within your factory.
