Raw & Freeze-Dried Pet Food: Microbial Safety

# Raw & Freeze-Dried Pet Food Safety

The FDA issued an advisory on Darwin's cat food in late October. At least 10 pet food recalls in 2026, most involving raw and freeze-dried products.

Why raw and freeze-dried carry risk

1. Raw meat ingredients naturally carry bacteria

2. Freeze-drying removes water but does not sterilize

3. Pet owners handle the product directly

Common pathogens

• Salmonella (raw chicken)
• E. coli (raw beef)
• Listeria (grows even at refrigeration temps)
• Mold (if packaging is damaged)

How co-packers control safety

1. Ingredient control

• Certified suppliers only
• Incoming microbial testing on every batch
• Cold chain maintained at 0-4°C
• Separate handling for different meats

2. Production environment

• Raw and cooked zones separated
• Air filtration
• Surface sanitation records
• Strict personnel hygiene

3. Process control

• Test before and after freeze-drying
• Water activity below 0.6
• Controlled packaging environment
• Metal detection

4. Finished product testing

Every batch must test: Salmonella, E. coli, total plate count, water activity.

What brands should do

1. Audit the factory — don't just look at photos

2. Label with raw food handling warnings

3. Keep every batch test report

4. Don't use words like "sterile" or "guaranteed safe"

MOQ and cost

• Freeze-dried raw: 300-500kg per SKU
• Testing: $140-$420 per batch
• 15-30% more expensive than regular freeze-dried

Common pitfalls

1. Choosing the cheapest factory

2. Not auditing in person

3. Missing warning labels

4. Skipping batch testing

If you want to launch raw or freeze-dried products, the most important thing is a co-packer with strict microbial QC. Mixiaoqi pet food OEM/ODM tests every batch for Salmonella and E. coli and can start with 300kg sampling.
