Microbiology Testing

Pathogen detection, indicator counts, environmental swabs and Legionella monitoring for food, water and surfaces.

Overview

Microbiology at CVR Labs

CVR Labs' microbiology division performs microbiology using validated IS and ISO culture and detection methods under NABL ISO/IEC 17025 accreditation. We detect pathogens, enumerate indicator and spoilage organisms, and verify environmental hygiene.

From pour-plate and membrane-filtration counts to selective enrichment and confirmation of pathogens, our microbiologists support FSSAI compliance, HACCP / FSMS / GMP verification, cleaning validation and shelf-life assurance — with results reported against the applicable microbiological criteria.

Why It Matters

Why this testing matters

Pathogen Control

Salmonella, Listeria, E. coli and S. aureus cause serious illness. Detection and indicator counts confirm your hygiene controls work.

FSSAI Microbial Limits

Microbiological criteria are defined for most food and water categories. Exceedances mean rejection and recall risk.

Hygiene Verification

Environmental and contact-surface swabs validate cleaning programmes and GMP / HACCP / FSMS compliance.

Shelf-Life Assurance

Spoilage and indicator organisms determine product stability and the safe shelf life you can declare.

Regulatory Context

Where these results are used

FSSAI Microbiological Criteria

Microbiological limits are defined for most food and water categories and enforced during surveillance and audits.

Schedule 4 — Hygiene & FSMS

FSSAI Schedule 4 requires hygiene and food-safety management systems verified by environmental and product testing.

IS / ISO Reference Methods

Detection and enumeration follow validated IS and ISO methods accredited under NABL.

HACCP / ISO 22000

Food-safety management systems rely on microbiological verification of CCPs, surfaces and product.

Cleanroom Standards

Controlled environments are monitored for air and surface bioburden to ISO 14644 / GMP expectations.

FAQ

Frequently asked questions

Which methods do you use?
We follow validated IS and ISO methods (e.g., IS 5887, IS 5402, ISO 4833, ISO 6579, ISO 11290) under NABL accreditation for detection and enumeration.
What organisms can you test for?
Salmonella, Listeria monocytogenes, E. coli, S. aureus, coliforms, Enterobacteriaceae, Vibrio, total plate count, yeast & mould, Legionella and more — depending on matrix.
Do you offer environmental and swab monitoring?
Yes. Air (settle-plate and active sampling), equipment swabs and food-contact-surface swabs are available for hygiene and cleaning-validation programmes.
How should microbiology samples be handled?
Send samples in sterile, sealed containers under refrigeration (2–8 °C) and deliver within 24 hours to preserve microbial integrity.
Can you support HACCP / FSMS verification?
Yes. Product, surface and water microbiology verifies critical control points and supports FSSAI Schedule 4, HACCP and ISO 22000.
Do you test cleanroom air and surfaces?
Yes. We monitor air and surface bioburden for controlled environments to GMP / ISO 14644 expectations.
What is the turnaround for microbiology?
Indicator counts are typically 3–5 days; pathogen detection requires selective enrichment and confirmation, usually within 5–7 days.
Can you enumerate Legionella?
Yes. We detect and enumerate Legionella in cooling towers and building water systems by culture methods.
