Microbiology testing solutions: Petrifilm and Compact Dry culture media

These plates replace traditional agar plates and petri dish prep with a dry, ready-to-use format. No media preparation, less equipment and results that are easy to read.

  • Total and aerobic count: Petrifilm Aerobic Count, Rapid Aerobic Count and Compact Dry TC
  • Coliforms and E. coli: Petrifilm E. coli/Coliform, Rapid Coliform, High-Sensitivity Coliform, Compact Dry EC and CF
  • Enterobacteriaceae: Petrifilm Enterobacteriaceae and Compact Dry ETB
  • Yeast and mould: Petrifilm Yeast & Mould, Rapid Yeast & Mould, Compact Dry YM and YMR
  • Specific microorganisms: Petrifilm Staph Express, Environmental Listeria, Compact Dry X-SA, X-BC (Bacillus cereus), SL (Salmonella) and LS (Listeria)

Automate and simplify microbial quantification

Petrifilm plates can be read by eye or with an automated reader. Compact Dry plates use chromogenic media, so target colonies show clear colours for easy counts.

01

Add the prepared food, water or swab sample to the plate.

02

Incubate at the temperature and time on the pack.

03

Count the colonies by eye or with a plate reader.

04

Record the result and act on anything out of specification.

Microbiology testing to identify Salmonella, Listeria, Campylobacter and other microbe risks

  • Raw material and finished product release
  • Environmental monitoring with swabs on food contact surfaces
  • Water quality checks
  • Shelf life and storage conditions studies
  • Investigating spoilage organisms and customer complaints

Food businesses from dairy and meat processors to bakeries use these methods. Checking for Campylobacter, Legionella in water systems and other pathogenic microbes also helps protect consumers.

Microbial testing in-house vs a testing laboratory

Many food businesses run routine counts in-house with Petrifilm or Compact Dry. It's faster, cheaper and gives you daily control. For pathogen confirmation, legal testing or heavy metals, use an accredited testing laboratory.

Most sites use both: in-house plates for quality control and an accredited lab for verification and regulatory compliance.

Microbiology testing questions

The basics of microbiological testing and the methods labs use.
What is microbiological testing? Microorganism, pathogen and microbial contamination checks for food safety

Microbiological testing finds and counts microorganisms in a sample. Indicator organisms like coliforms and Enterobacteriaceae show how clean your process is. Pathogen tests look for harmful bacteria, including Salmonella. Together they help you control microbial contamination from raw material to finished product. See our pathogen testing kits for targeted surface checks.
Common microbiology testing methods: plating, PCR assay, real-time PCR and more
  • Plating and culture media: the standard method for counts, using agar plates or Petrifilm
  • Real-time PCR: a PCR assay detects microbial DNA, giving rapid testing for pathogens
  • Biochemical, enzymatic and phenotypic tests: used to confirm bacterial strains
  • Sequencing: used by microbiology laboratories for taxonomic and epidemiological work
  • Antimicrobial susceptibility testing: checks antimicrobial resistance, mainly in clinical and research settings
What equipment do I need to run plates in-house?

At minimum, an incubator that holds a steady temperature. Our lab equipment range includes the Cultura Incubator, which holds at least 80 Petrifilm plates.
