Pet food manufacturers face increasing expectations regarding product quality, nutritional accuracy, ingredient verification, and microbiological safety.

Whether producing:

Dry pet food Wet pet food Raw pet food Freeze-dried products Treats Supplements

testing plays an important role in supporting product quality and manufacturing consistency.

The right testing program helps manufacturers answer critical questions:

  • Does the product meet nutritional targets?
  • Are microbiological controls working?
  • Are ingredients consistent?
  • Are pathogens absent where required?
  • Does the product perform as intended?

PBR Laboratories provides pet food testing services throughout Alberta, Western Canada, and Canada.

Why Is Pet Food Testing Important?

Pet food testing supports:

◆ Product Quality
◆ Nutritional Verification
◆ Ingredient Quality Programs
◆ Supplier Verification
◆ Food Safety Programs
◆ Product Development
◆ Customer Confidence
◆ Manufacturing Consistency

Common Pet Food Testing Categories

Most pet food testing programs include a combination of:

Food Microbiology Testing
Food Pathogen Testing
Nutritional Analysis
Ingredient Analysis
Moisture Content Testing
Water Activity (aw) Testing
Shelf-Life Testing
Environmental Monitoring

Pet Food Microbiology Testing

Microbiology testing helps evaluate overall product quality and manufacturing controls.

Common tests include:

Aerobic Plate Count (APC)

Provides information regarding overall microbial populations.

Total Coliforms

Used as sanitation indicators.

Escherichia coli (E. coli)

Provides hygiene-related information.

Enterobacteriaceae

Evaluates process control and sanitation performance.

Yeast & Mold

Supports shelf-life and product stability evaluations.

Pet Food Pathogen Testing

Depending on product type and risk profile, testing may include:

Salmonella spp.
Listeria monocytogenes
Escherichia coli (E. coli) O157:H7
Non-O157 STEC
Bacillus cereus
Clostridium perfringens

Pathogen testing is commonly incorporated into verification programs, investigations, and supplier qualification activities. See also: Food Pathogen Testing Requirements in Canada.

Nutritional Analysis for Pet Food

Nutritional analysis helps manufacturers verify formulation targets and product consistency.

Common parameters include:

Protein
Fat
Moisture
Ash
Fibre
Carbohydrates

Testing supports:

◆ Formulation Verification
◆ Product Development
◆ Label Development
◆ Quality Assurance Programs

Ingredient Analysis

Ingredient testing may be used to verify:

◆ Incoming Ingredient Quality
◆ Supplier Consistency
◆ Formulation Targets
◆ Manufacturing Specifications

Testing is commonly performed on:

Meat ingredients
Poultry ingredients
Grains
Supplements
Functional ingredients

Water Activity (aw) Testing

Water Activity (aw) is one of the most important shelf-life parameters.

Water activity influences:

◆ Microbial Growth
◆ Product Stability
◆ Packaging Requirements
◆ Shelf Life
◆ Product Quality

Moisture Content Testing

Moisture content helps evaluate:

◆ Product Consistency
◆ Manufacturing Performance
◆ Stability
◆ Shelf-Life Performance
◆ Ingredient Quality

Shelf-Life Testing

Shelf-life studies help determine:

◆ Product Stability
◆ Best Before Dates
◆ Packaging Performance
◆ Product Quality Trends
◆ Storage Performance

Testing may include:

Microbiology
Water Activity (aw)
Moisture Content
Organoleptic Evaluation

Environmental Monitoring

Environmental monitoring programs help identify contamination risks before products are affected.

Programs commonly include:

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

Sampling may include:

Equipment
Drains
Floors
Food contact surfaces
Processing environments

What Decisions Does Pet Food Testing Support?

Product Release
Supplier Approval
Nutritional Verification
Food Safety Programs
Shelf-Life Validation
Product Development
Corrective Actions
Continuous Improvement Programs

Common Testing Mistakes

Testing Only Finished Products

Ingredient and environmental monitoring data are equally valuable.

Ignoring Nutritional Verification

Nutritional consistency should be routinely evaluated.

Not Trending Results

Trend analysis often provides the most useful information.

Treating All Products The Same

Different product categories may require different testing strategies.

Failing To Review Shelf-Life Data

Product stability should be routinely assessed.

Frequently Asked Questions

Food microbiology testing, pathogen testing, nutritional analysis, ingredient testing, water activity testing, moisture content testing, shelf-life testing, and environmental monitoring.

It helps verify formulation targets, product consistency, and quality objectives.

Salmonella spp., Listeria monocytogenes, Escherichia coli (E. coli) O157:H7, and others depending on product risk.

Water Activity (aw) influences microbial growth, stability, and shelf life.

Yes. Shelf-life studies help determine product stability and support best before dates.

Environmental monitoring helps identify contamination risks before products are affected.
