Food pathogen testing helps manufacturers identify microorganisms capable of causing foodborne illness, product recalls, regulatory action, customer complaints, and brand damage.

PBR Laboratories provides pathogen testing services for food products, ingredients, environmental samples, ready-to-eat foods, meat products, dairy products, seafood products, and raw pet food throughout Alberta, Western Canada, and Canada.

Understanding a positive pathogen result is just as important as obtaining it. PBR helps clients understand results and determine appropriate next steps.

What Is Food Pathogen Testing?

Food pathogen testing identifies microorganisms that can cause foodborne illness.

Unlike routine microbiology testing, which focuses on quality indicators and spoilage organisms, pathogen testing targets specific microorganisms associated with human or animal health risks.

Pathogen testing supports:

  • Food safety programs
  • HACCP verification
  • Product release decisions
  • Environmental monitoring programs
  • Regulatory investigations
  • Customer requirements
  • Root cause investigations

Who Needs Food Pathogen Testing?

Food pathogen testing is commonly used by:

Ready-to-Eat Food Manufacturers
Meat Processors
Poultry Processors
Dairy Manufacturers
Seafood Processors
Ingredient Suppliers
Raw Pet Food Manufacturers
Co-Packers
Food Importers
Food Exporters

What Happens When Pathogens Are Detected?

Detection of a pathogen may result in:

✘ Product holds
✘ Corrective actions
✘ Expanded sampling
✘ Environmental investigations
✘ Root cause analysis
✘ Customer notifications
✘ Regulatory reporting
✘ Product recalls

The response depends on: product type, intended use, customer requirements, regulatory expectations, and food safety program requirements.

PBR helps clients understand what results mean and what actions may be appropriate.

Frequently Asked Questions

Food pathogen testing identifies microorganisms capable of causing foodborne illness and food safety concerns.

Routine microbiology evaluates quality indicators and spoilage organisms. Pathogen testing targets organisms associated with illness and food safety risks.

Common pathogen tests include Salmonella, Listeria monocytogenes, E. coli O157:H7, STEC, Bacillus cereus, Clostridium perfringens, Campylobacter, and Staphylococcus aureus.

A positive result indicates the target organism was detected and further evaluation may be required.

Testing may be performed during routine production, product release programs, environmental monitoring, investigations, and customer verification programs.

Food products, ingredients, environmental samples, ready-to-eat foods, meat products, poultry products, seafood products, dairy products, and raw pet food.

The response depends on the product, organism detected, regulatory requirements, and customer specifications.

Testing frequency depends on product risk, food safety plans, customer requirements, and regulatory expectations.
