What is Enterococci Testing?

Enterococci are a family of bacteria present in nature, with some species of the enterococci family being dangerous to humans.

In drinking water, enterococci presence indicates the presence of environmental contamination (specifically faecal contamination as naturally these bacteria reside in the gut microbiome of humans and animals), which can lead to dangerous clinical manifestations.

Enterococci are used as indicators of water quality and faecal contamination in various environments. Enterococci are considered indicator organisms for faecal contamination because they are more resistant to environmental conditions than other faecal indicator bacteria, such as E. coli. This means they can survive longer in the environment and are more likely to be present in water sources contaminated with faeces.

Testing for enterococci in drinking water is essential because these bacteria can indicate the presence of faecal contamination in the water source. In addition, if enterococci are present in drinking water, other disease-causing organisms are likely to present, which can pose a health risk to people who consume the water.

Regular enterococci testing in drinking water helps to ensure that the water is safe to drink. Water treatment or other control measures can be implemented if contamination is found to reduce the risk of illness. Additionally, it can help identify contamination sources and track control measures’ effectiveness over time.

What is the Importance of Enterococci Testing?

Research has shown that these bacteria cause enterococcal infections that range in severity, including:

    • Urinary tract infections (UTIs)
    • Bloodstream infections
    • Infections of the heart (endocarditis)
    • Infections of the lining of the brain tissue (meningitis)

For the safety of your family, monitoring for enterococci helps identify potential risks to your family’s health and enables water suppliers to take appropriate action to address any potential risks to your safety.

It’s especially crucial to ensure the safety of your drinking water if your household includes:

    • Children
    • Pregnant or nursing individuals
    • Elderly household members
    • Anyone with a weakened immune system
    • New homeowners unfamiliar with their water source

Why Choose Southern Scientific Enterococci Testing?

With Southern Scientific, you get:

    • 240,000+ samples tested every year for over 2,000 clients across Ireland
    • A rapid 24-hour turnaround of Enterococci results in emergency cases (after we receive your sample)
    • An INAB-accredited laboratory (ISO 17025, Reg. 194T)
    • 100 onsite field experts working from 4 offices across 3 provinces
    • A team that keeps up to date with the latest scientific evidence and regulations

In 2020, the Drinking Water safety regulations in Ireland were updated to reflect the latest scientific evidence to improve the quality of drinking water and monitor levels of specific bacteria, including enterococci. Under these regulations, drinking water should contain no enterococci in a 100 ml sample. Any detection is classed as an exceedance and must be investigated to identify and address the source of contamination.

What is the Process for Testing?

Enterococci testing is used to analyse drinking water samples at Southern Scientific. Initially, water samples are collected and transported to our accredited laboratory while maintaining proper preservation conditions. In the lab, samples are prepared through filtration and placed on culture media that encourage Enterococci growth (if present in the sample). After an incubation period, trained technicians count the resulting colonies, providing a quantification of Enterococci. Additional tests may be performed for confirmation. The data is meticulously analysed, and a comprehensive report is generated, offering precise insights into water quality. This method ensures the accurate assessment of potential contamination, helping safeguard the safety of drinking water supplies.

FAQs

What does Enterococci in my water sample mean?
The presence of Enterococci in a drinking water sample indicates environmental contamination, specifically faecal contamination, which can mean other harmful pathogens are also present.

What is the legal limit for Enterococci in Irish drinking water?
Since 2020, Ireland’s Drinking Water Safety Regulations require drinking water to contain no Enterococci in a 100ml sample.

How is my sample tested for Enterococci?
Your sample is transported to our INAB-accredited laboratory under proper preservation conditions, then filtered and placed on culture media that encourage Enterococci growth for identification.

Who is most at risk from Enterococci contamination?
Children, pregnant or nursing individuals, elderly household members, anyone with a weakened immune system, and new homeowners unfamiliar with their water source are most at risk.

How quickly will I get my results?
We offer a rapid 24-hour turnaround for emergency cases, once we’ve received your sample. Contact our team to discuss standard turnaround for your specific test.
