HYGIENE TESTING

Hygiene Testing (Environmental Monitoring)

Contaminated surfaces, air and equipment are among the common and preventable sources of product contamination in pharmaceutical manufacturing and food processing. DALPL’s hygiene testing panel covers personnel hygiene, surface cleanliness and air quality across production environments.

Why Hygiene Testing Matters

Maintaining hygiene in production environments helps identify potential sources of contamination and supports consistent manufacturing and food-processing practices.

Personnel Hygiene

Assess hygiene indicators and specified organisms through hand, apron and machine swab testing.

Surface Cleanliness

Test measured production and equipment surfaces for specified hygiene indicators and microorganisms.

Air Quality Monitoring

Use settle-plate and plate-exposure methods to monitor classified and non-classified production areas.

Our Hygiene Testing Services

Comprehensive sampling and analysis across the three primary vectors of environmental contamination.

Personnel Monitoring

Sampling

Hand swabs, apron swabs and machine swabs.

Parameters Tested
  • Shigella

Surface Monitoring

Sampling

Swab testing of measured production and equipment surfaces.

Parameters Tested
  • Coliform
  • Escherichia coli (E. coli)
  • Listeria monocytogenes
  • Pseudomonas aeruginosa
  • Salmonella spp.

Regulatory Framework & Context

Food Hygiene Requirements

FSSAI Schedule 4 — Good Manufacturing and Good Hygienic Practices (GMP/GHP) for food business operators

Hygiene testing can support a facility’s hygiene-control programme. Schedule 4 does not establish a specific swab-testing mandate; rather, testing is used proactively to help ensure effective hygiene practices.

Relevant Contextual Frameworks

Testing operations may intersect with the following frameworks across different industries:

  • Revised Schedule M under the Drugs Rules, 1945
  • EU GMP Annex 1 for manufacture of sterile medicinal products
  • ISO 14644 cleanroom classification

Note: These are relevant contextual frameworks. DALPL does not certify blanket compliance or claim that every listed test is prescribed by each framework.

Frequently Asked Questions

What types of hygiene testing does DALPL offer?
The page covers personnel monitoring, surface monitoring and air monitoring.
What is included in personnel monitoring?
Hand, apron and machine swab testing for Shigella, Staphylococcus aureus, Total Aerobic Count, and Yeast and Mould Count.
What is included in surface monitoring?
Surface swab testing for Coliform, E. coli, Listeria monocytogenes, Pseudomonas aeruginosa, Salmonella spp., Shigella, Staphylococcus aureus, Total Aerobic Count, and Yeast and Mould Count.
How is air monitoring performed?
The described methods are settle-plate and plate-exposure testing in classified and non-classified areas. The source identifies ISO 14644 as the cleanroom-classification context; do not imply DALPL certifies cleanrooms.
Does DALPL also provide hygiene consulting?
Yes. The source lists sampling programme design, trend analysis, alert/action level setting, cleaning process validation support, disinfectant rotation assessment, environmental control measure assessment, site visits and staff hygiene training. Present these separately from the accredited laboratory panel.
Does FSSAI Schedule 4 prescribe a specific swab-testing panel?
The source document notes that FSSAI Schedule 4 does not establish a specific swab-testing mandate. Hygiene testing may support a facility’s hygiene-control programme, but do not claim this panel is legally mandatory.
