Raw pet food manufacturers face unique food safety and quality challenges.

Unlike fully cooked products, raw pet foods may contain ingredients that require careful microbiological monitoring and verification.

Testing programs are often designed to help answer important questions:

  • Are food safety controls working?
  • Are pathogens present?
  • Is product quality consistent?
  • Do results meet customer requirements?
  • Are environmental controls effective?

A risk-based testing program helps manufacturers verify product quality, support food safety programs, and make informed release decisions.

PBR Laboratories provides raw pet food testing, food pathogen testing, food microbiology testing, environmental monitoring, and ingredient testing services throughout Alberta, Western Canada, and Canada.

WHY IS RAW PET FOOD TESTING IMPORTANT?

Raw pet food products often contain:

Raw Meat Ingredients
Poultry Ingredients
Organ Meats
Animal By-Products
Raw Food Components

These ingredients may require additional microbiological verification compared to fully cooked products.

Testing helps support:

Food Safety Programs
Supplier Verification
Product Quality Programs
Manufacturing Verification
Customer Requirements
Product Release Decisions

WHAT TESTING IS COMMONLY PERFORMED?

Testing requirements vary by product and program objectives.

Common testing categories include:

Food Pathogen Testing
Food Microbiology Testing
Environmental Monitoring
Ingredient Testing
Shelf-Life Testing

SPECIFIC PATHOGENS & INDICATORS

SALMONELLA SPP. TESTING

Salmonella spp. is one of the most commonly requested tests for raw pet food products.

Testing may be performed on:

  • Finished Products
  • Raw Ingredients
  • Environmental Samples
  • Supplier Verification Samples
Typical Reporting Format: Detected or Not Detected
LISTERIA MONOCYTOGENES TESTING

Listeria monocytogenes testing may be incorporated into:

  • Product Verification Programs
  • Environmental Monitoring Programs
  • Investigative Testing
  • Risk-Based Monitoring Activities
Typical Reporting Format: Detected or Not Detected
ESCHERICHIA COLI (E. COLI) O157:H7 TESTING

Escherichia coli (E. coli) O157:H7 may be included in testing programs involving:

  • Raw Meat Ingredients
  • Finished Raw Pet Food Products
  • Supplier Verification Programs
  • Product Verification Activities
Typical Reporting Format: Detected or Not Detected
GENERIC ESCHERICHIA COLI (E. COLI)

Generic Escherichia coli (E. coli) is commonly used as an indicator organism.

Results may help evaluate:

  • Hygiene Conditions
  • Process Controls
  • Ingredient Quality
  • Manufacturing Consistency
Results are typically reported as: Colony Forming Units per Gram (CFU/g)
TOTAL COLIFORMS

Total Coliform testing may help evaluate:

  • Sanitation Effectiveness
  • Process Controls
  • Supplier Quality
  • Manufacturing Conditions
Results are commonly reported as: Colony Forming Units per Gram (CFU/g)
AEROBIC PLATE COUNT (APC)

Aerobic Plate Count (APC) provides information regarding:

  • Overall Microbial Populations
  • Product Consistency
  • Ingredient Quality
  • Production Trends
Results are commonly reported as: Colony Forming Units per Gram (CFU/g)
ENTEROBACTERIACEAE TESTING

Enterobacteriaceae testing is frequently used to evaluate:

  • Environmental Hygiene
  • Process Control
  • Ingredient Quality
  • Sanitation Performance

The test often complements Total Coliform and Generic Escherichia coli (E. coli) testing.

ENVIRONMENTAL MONITORING FOR RAW PET FOOD FACILITIES

Environmental monitoring helps manufacturers identify contamination risks within the production environment.

Programs may include:

Listeria spp.
Listeria monocytogenes
Salmonella spp.
Total Coliforms
Enterobacteriaceae
Aerobic Plate Count (APC)

Common sampling locations include:

Equipment
Floors
Drains
Food Contact Surfaces
Processing Areas

INGREDIENT TESTING

Ingredient testing may help evaluate:

Incoming Raw Materials
Supplier Performance
Risk Management Programs
Product Consistency

Common ingredient testing may include:

  • Pathogen Testing
  • Indicator Organism Testing
  • Quality Verification Testing

WHAT RESULTS SHOULD MANUFACTURERS TREND?

One of the most valuable activities is trend analysis.

Results commonly reviewed include:

Salmonella spp.
Listeria monocytogenes
Generic Escherichia coli (E. coli)
Total Coliforms
Enterobacteriaceae
Aerobic Plate Count (APC)
Environmental Monitoring Results

Trend analysis often provides more useful information than individual test results.

WHAT SHOULD HAPPEN AFTER A POSITIVE RESULT?

Step 1 – Review Product Information
Step 2 – Review Ingredient Sources
Step 3 – Review Environmental Monitoring Results
Step 4 – Conduct Root Cause Investigations
Step 5 – Implement Corrective Actions
Step 6 – Verify Effectiveness Through Follow-Up Testing

Testing should support decision-making and continuous improvement.

COMMON TESTING MISTAKES

Testing Only Finished Products

Environmental monitoring and ingredient testing are also important.

Ignoring Trend Analysis

Historical results often provide valuable insight.

Using The Same Program For Every Product

Testing should be risk-based.

Failing To Investigate Positive Results

Positive findings should trigger evaluation and action.

Not Reviewing Supplier Performance

Ingredient quality significantly influences final product quality.

WHAT DECISIONS DOES RAW PET FOOD TESTING SUPPORT?

Product Release Decisions
Supplier Verification
Food Safety Programs
Environmental Monitoring Programs
Corrective Action Programs
Continuous Improvement Initiatives
Product Quality Programs

WHY RAW PET FOOD TESTING MATTERS

Raw pet food testing helps manufacturers:

  • Verify food safety controls
  • Evaluate microbiological risks
  • Monitor environmental conditions
  • Assess ingredient quality
  • Support product consistency
  • Improve decision-making

The goal is not simply generating laboratory results.

The goal is using data to support food safety, quality, and operational performance.

FAQ

What pathogens are commonly tested in raw pet food?
