Pathogen testing (Salmonella, Listeria, E. coli O157) and indicator organisms (coliforms, S. aureus, yeast & mould) require disciplined workflow and reliable media supply.
Workflow & Supplies
- Sample prep: Stomacher bags, sterile diluents (peptone water, buffered peptone)
- Enrichment broths: BPW, RV broth, selenite cystine broth
- Plating media: XLD, SS, Baird-Parker, VRBA, Y&M agar
- Incubators: 37°C bacterial, 25°C fungal (adjust per method)
- Confirmation: Biochemical kits, latex agglutination (where applicable)
