NviroTek Laboratories
A multitude of laboratory tests are performed to assist with valuable decision making regarding the following:
Microbiological Samples
The microbiology laboratory at Wellington is well equipped to do screening for pathogens and to assist with hygiene monitoring at processing plant and abattoirs

- Microbiology information:
Detection = Samples placed in nutrient rich broth to ensure that organisms multiply. If only one organism was present, it will be detected
Enumeration= Samples are tested as they are received, and count given good indication of how many are present in the sample
Presumptive positive test of pathogens have to be confirmed with other test method (ISO 17025 requirement)
Samples to be kept chilled and delivered within 24 hours of sampling.
How much sample do I need to send?
- Foodstuff: 75-100g
- Water/wine: 500ml
- Swabs: 1 swab or 1 additional swab per pathogen tested (Salmonella, Listeria, E.coli 0157)
Samples can be sent to NviroTek Wellington or can be picked up free of charge if on our predetermined route
