Virology and Parasitology in Water

What Are Waterborne Viruses and Parasites?

Waterborne viruses and parasites are pathogenic microorganisms that contaminate drinking water, recreational water, or food prepared with unsafe water. These biological contaminants are responsible for a wide range of diseases, including gastroenteritis, hepatitis, cholera-like symptoms, and other serious infections.

At Eurofins, we help clients ensure that their water sources meet the highest microbiological safety standards through advanced virological and parasitological testing. Our testing protocols are designed to detect, quantify, and characterize harmful viruses and parasites that may compromise public health and regulatory compliance.

Why Testing for Viruses and Parasites in Water Is Essential

At Eurofins, we emphasize the necessity of testing for virological and parasitological contaminants due to:

• Public Health Protection: To prevent outbreaks of waterborne diseases caused by pathogens such as Cryptosporidium, Giardia, Hepatitis A virus, Norovirus, and Enterovirus.
• Regulatory Compliance: To comply with WHO, EU, US EPA, and national standards that mandate zero-tolerance for specific viral and parasitic pathogens in potable water.
• Risk Mitigation: To detect contamination early and prevent large-scale community transmission.
• Quality Assurance for Industries: To support food and beverage manufacturers, bottled water producers, and wastewater treatment facilities in maintaining hygienic water quality.

Types of Virology and Parasitology Tests We Offer

Eurofins provides comprehensive analytical solutions to detect a wide range of waterborne viruses and parasites, employing the most advanced and globally validated methods.

• Viral Detection: Molecular assays for Norovirus, Rotavirus, Hepatitis A, and Enteroviruses using RT-PCR and qPCR platforms.
• Parasitological Identification: Concentration and microscopy-based detection of Cryptosporidium oocysts and Giardia cysts following ISO 15553:2006 and USEPA 1623.1 methods.
• Indicator Pathogen Testing: Monitoring for E. coli and Clostridium perfringens as proxies for viral or parasitic contamination.
• Emerging Pathogen Surveillance: Environmental RNA/DNA testing for newly identified waterborne viruses such as SARS-CoV-2.

All analyses are carried out in ISO/IEC 17025-accredited laboratories using globally harmonized protocols.

How Our Testing Process Works

At Eurofins, testing for virology and parasitology in water follows a stringent, step-by-step scientific protocol to ensure accuracy and traceability:

• Sample Collection: Sterile, contamination-free collection using standard containers. Detailed instructions provided for volume, temperature, and holding time.
• Sample Concentration: Advanced ultrafiltration and centrifugation techniques to recover low-concentration pathogens.
• Molecular and Microscopic Analysis: Detection through PCR, immunofluorescence, and staining methods.
• Quality Control: Dual confirmation through positive/negative controls, reference strains, and proficiency testing.
• Turnaround Time (TAT): Standard reports within 3–5 working days; express testing options available within 24–48 hours.
• Reporting: Comprehensive result interpretation with recommendations for remedial actions or process validation.

Who Needs Virology and Parasitology Testing?

Our specialized testing services are ideal for:

• Water treatment plants and utilities ensuring safe distribution networks
• Bottled water and beverage producers verifying source water safety
• Food industries using process water for production or washing
• Hospitals, hotels, and institutions relying on large water systems
• Environmental monitoring and research agencies studying public health risk factors

Common Challenges We Help Clients Overcome

Case Study: Restoring Potability in a Municipal Water Network

A municipal water authority reported recurring gastrointestinal illnesses among residents. Eurofins conducted rapid parasitological and virological testing using concentration and PCR techniques. Results confirmed the presence of Cryptosporidium oocysts in untreated surface water entering the distribution system. With our technical guidance, filtration and disinfection processes were upgraded, and subsequent testing confirmed complete pathogen elimination. This resulted in restored consumer confidence and full regulatory compliance.
