Microbial enumeration & detection – food products

All test methods are based on standard methods and are included in our scope of accreditation under the Campden Laboratory Accreditation Scheme and include:

Aerobic Plate Count (mesophilic aerobic bacteria)

Total Fungal Count

Enumeration of specific micro-organisms, including:

  • Enterobacteriaceae
  • coliforms
  • E coli
  • Pseudomonas and related species
  • coagulase positive gram positive cocci
  • faecal streptococci
  • B cereus
  • mesophilic bacterial spores
  • presumptive Lactobacillus sp
  • Clostridium perfringens
  • presumptive Listeria / L monocytogenes

Detection of specific micro-organisms, including:

  • Salmonella (in 25g)
  • presumptive Listeria / L monocytogenes (in 25g)
  • where appropriate, includes confirmatory testing at no additional charge.

Shelf life confirmation:

Donnington Laboratories can assist with the design and conduct of microbiological shelf life trials. In the case of longer term trials, it is our standard practice to issue regular interim updates by e-mail.

Dietary and nutritional supplement testing:

Nutritional and dietary supplements marketed in tablet or capsule form can lie in the grey area between foods and medicines, particularly when marketed outside the EU. In addition to the standard food tests listed above, Donnington Laboratories are happy to apply the testing methods described in the British and European Pharmacopoeias to these products. These techniques also appear in our scope of CLAS accreditation.
