  • Campylobacter

The micro-organisms that we test and report in compost and growing media's as counts/gram of material:
  • Faecal coliforms
  • E.coli
  • Salmonella
  •  Campylobacter

Please request if you required a present or absent test or counts/gram test for Salmonella or Campylobacter.


Taking a sample

Collect 300g of representative sample by collecting 10 small hand grab samples. Use a labelled sterile jar or other resealable clean plastic bag and squeeze air from the bag. Samples should be kept chilled and sent to the lab within 24 hours of sampling. If you require sterile jars for sampling, order the 400ml STER plastic jars (order code "STER").
