  • Vibrio cholera
  • Vibrio parahaemolyticus
  • Pathogenic streptococci
  • Staphylococcus aureus
  • Pseudomonas aeruginosa
  • Legionella
  • Campylobacter jejuni

  • Bacillus cereus
  • Salmonella
  • Shigella
  • Listeria monocytogenes

Protocols /Techniques Followed

  • APHA
  • BIS
  • ASTM
  • AOAC
  • Conventional Methods

Enumeration Of Spoilage Microbes

Micro-organisms are ubiquitous in nature. Quality and shelf life of any product depends on presence and nature of micro-organisms contained in it. Under favourable conditions these micro organisms proliferate and result in loss of product quality. Microbiological monitoring is an essential part of quality control. ITL labs plays an important role in testing and certification.

Test Parameters

  • Standard Plate Count
  • Coliform / Faecal Coliforms
  • Psychrophilic and Thermophilic
  • Aerobic and an-aerobic spore formers
  • Rope Spore Count
  • Anaerobic Bacteria
  • Sulphite Reducing Bacteria
  • Sulphur and Iron Bacteria
  • Yeast and Moulds

Residual Anti-Microbial Substances

Food-producing animals are given antimicrobial drugs for prevention of disease and for their well being. The residues of these antimicrobial drugs remain in and on the body of the animals.

Following anti-microbial residues are being tested at ppb levels using ELISA techniques.
  • Tetracyclines
  • Sulfonamides
  • Streptomycin
  • Chloramphenicol
  • Gentamycin
  • Neomycin
  • Nitrofurans etc .

Bacterial Enterotoxins

Bacteria produces Enterotoxins as a part of their metabolic activities. Some of them are heat labile while others are heat stable in nature. Even severe food processing treatments can not eradicate these toxicants and may result in food intoxication.
SRI undertakes testing of the following Enterotoxins in food and food products.

  • Bacillus cereus Diarrhoeal enterotoxins
  • Staphylococcal enterotoxins


Mycotoxins are carcinogenic, highly toxic metabolites of fungi like Aspergillus, Fusarium and Penicillium. They are toxic even in trace quantities

  • Aflatoxins -Aflatoxin B1, B2, G1, G2, M1
  • Fumonisin
  • Deoxynivalenol (Vomitoxin)
  • Ochratoxin A
  • Zearalenone
  • T-2 toxin etc.

Monitoring of Indoor Air

ITL labs carries out air-monitoring studies for presence of microbes. Services are provided in the following areas

  • Storage Godowns
  • Hotels/Restaurants
  • Food Processing/Packaging Areas
  • Clean Rooms/Clean Air Devices
  • Operation Theatres and Intensive care units in hospitals

Preservative Efficacy

Nanotechnology In pharmaceutical, herbal and cosmetic formulations, various anti-microbial substances are added to arrest microbial activity and extend shelf life of the products. The effectiveness of these substances are evaluated as per USP protocols. Selection of challenge micro-organisms include gram positive and gram negative bacteria, spore formers, yeast and fungi.

Disinfection Efficacy

The Phenolic and non-phenolic type disinfectants are being tested for their germicidal value as per National and International protocols.

We Serve Better Than Any Other!

ITL Labs provides state of the art services, both for quality assurance of Raw materials and finished products of various industries. Besides this, the expertise of ASD (Analytical services division) work as a support for regulatory authorities as well the consumers. The methods adopted are of International standards.
