Water systems contamination

Biofilms are layers of bacteria formed inwater systems’ pipes and cause contamination, even if authorities regularly inspect their water supply network.

Bacterial layers in water systems are among the most significant challenges to be identified, in industry and agriculture and in clinics, trains, aircraft, hotels, restaurants, swimming pools and spas.

An article published in Comprehensive Reviews in Food Science & Food Safety demonstrated that irrigation water contamination has led to outbreaks of infections among fresh vegetable consumers. This trend has been growing, especially with changes in the lifespan of fresh vegetables for consumption.

The article deals with fresh food products that are particularly vulnerable to microbial contamination originating from irrigation water quality and water systems’ contaminants. Water is a significant source of microbial contamination and irrigation water specifically affects some agricultural produce.

Microbial Contamination of Fresh Produce: What, Where, and How?

Available, accessible and rapid microbial testing of irrigation water quality can detect microbial and chemical contaminants in that may impair the quality of agricultural produce marketed to the consumer.

Immediate detection of water contamination is critical in the case of Legionella. According to the EPA, the U.S. Environmental Protection Agency, this bacterium, which can cause lung disease and death, is common in water systems such as cooling towers, air conditioning and in tap water. In addition, Legionella is relatively resistant to disinfectants used in water systems, including drinking water.
