Pseudomonas aeruginosa is pathogenic and is a common target for the food and pharmaceutical industries.
Pseudomonas aeruginosa is a psychrotrophic bacterium and can proliferate at low temperatures, causing spoilage of refrigerated food products such as meat, poultry, fish, milk, and dairy products.
It is ubiquitous and thrives in soil, fresh water, and marine environments. Aside from food products, it is also known to contaminate clinical environments and cosmetics/pharmaceutical products.
