What Are Potentially Hazardous Foods? Guide to Food Safety in Australia
Key Takeaways on Potentially Hazardous Foods (PHFs)
- PHFs require strict time and temperature control to stop bacteria from multiplying.
- Common PHFs include meat, poultry, seafood, dairy, eggs, cooked rice/pasta, and salads.
- The temperature danger zone is 5°C–60°C, where harmful bacteria grow fastest.
- FSANZ and state laws set strict food safety rules for handling PHFs.
- Mishandling PHFs can cause foodborne illness, legal penalties, or business closure.
- Staff training and certification are required to stay compliant.
Introduction: Why PHFs Matter in Australia
Every year, foodborne illnesses affect thousands of Australians, many caused by improper handling of potentially hazardous foods (PHFs). For food handlers, supervisors, and businesses, understanding what qualifies as a PHF—and how to manage it safely—is essential for compliance, customer safety, and business reputation.
Definition Under Australian Food Safety Standards
Potentially hazardous foods (PHFs) are foods that need strict temperature control to limit the growth of harmful microorganisms or the production of toxins.
According to Food Standards Australia New Zealand (FSANZ), PHFs usually have high moisture, neutral to low acidity, and rich nutrients—perfect conditions for bacteria to thrive if left unmanaged.
Characteristics of PHFs
PHFs typically share three traits:
- High moisture content → supports microbial growth.
- Low to neutral pH → ideal for harmful bacteria.
- Rich nutrients → provide food for pathogens.
Examples of Common PHFs in Australia
- Raw and cooked meat, including poultry
- Seafood (raw, cooked, or ready-to-eat)
- Dairy products (milk, cheese, cream)
- Cooked rice and pasta
- Prepared salads (coleslaw, potato salad)
- Egg-based dishes and desserts
- Foods containing cream or custard
Why PHFs Are Considered Hazardous
The Temperature Danger Zone (5°C–60°C)
When PHFs are left between 5°C and 60°C, bacteria multiply rapidly. This range is known as the temperature danger zone and is the biggest risk factor for foodborne illness.
Pathogen Growth and Foodborne Illnesses
Poor handling can result in contamination with:
- Salmonella
- Listeria monocytogenes
- Clostridium perfringens
- Escherichia coli (E. coli)
These pathogens are linked to serious illness, hospitalisation, or even death.
Legal Obligations and Standards in Australia
FSANZ Requirements
PHFs must be stored, displayed, and transported at safe temperatures. Food businesses must comply with the Australia New Zealand Food Standards Code, which sets strict rules for PHFs.
State-Based Regulations
States and territories enforce these laws through audits and inspections. Breaches may result in:
- Heavy fines
- Closure orders
- Prosecution
Safe Handling Practices for PHFs
Time and Temperature Control
- Keep cold food at ≤5°C
- Keep hot food at ≥60°C
- Cool cooked PHFs from 60°C → 21°C within 2 hours, then to 5°C within 4 hours
Preventing Cross-Contamination
- Use separate cutting boards and utensils
- Clean and sanitise surfaces frequently
- Store raw and cooked food separately
Personal Hygiene and PPE Use
- Wash hands thoroughly and often
- Wear gloves (change between tasks)
- Use clean clothing, aprons, and hairnets
Storage and Transport Guidelines
Cold Storage
- Refrigerators at ≤5°C
- Freezers at ≤-15°C
- FIFO system for stock rotation
- Label and date all stored foods
Hot Holding
- Maintain PHFs at ≥60°C
- Discard if held beyond safe limits
Transporting PHFs
- Use insulated, temperature-controlled containers
- Monitor and record transport temperatures
- Reduce time in the danger zone
Examples of PHFs by Category
Animal-Origin PHFs
- Meat and poultry
- Seafood
- Dairy products
- Eggs
Plant-Based PHFs
- Cooked rice and pasta
- Tofu and soy products
- Vegetable-based salads
Ready-to-Eat PHFs
- Sushi
- Deli meats
- Sandwiches with perishable fillings
- Cream or custard desserts
Risks of Poor PHF Management
Common Mistakes
- Leaving food unrefrigerated
- Reheating incorrectly
- Not labelling or dating food
Case Studies in Australia
- Listeriosis linked to soft cheese
- Salmonella outbreaks from undercooked eggs
Training & Education on PHFs
Food Safety Supervisor Requirements
Every food business must appoint a Food Safety Supervisor (FSS) who holds an accredited qualification.
Online Courses and Workplace Training
Options include:
- Government training programs like DoFoodSafely
- Accredited short courses for food handler certification (SITXFSA005)
Frequently Asked Questions (FAQs)
What are potentially hazardous foods?
Foods that require temperature control to prevent harmful bacteria growth.
Why is cooked rice considered hazardous?
Because its moisture and nutrients make it a perfect breeding ground for bacteria when stored at unsafe temperatures.
How should PHFs be stored in a fridge?
At or below 5°C, sealed in clean, labelled containers.
What is the temperature danger zone?
5°C–60°C, the range where bacteria multiply fastest.
Are eggs considered PHFs?
Yes, particularly raw or lightly cooked eggs.
What are the consequences of poor handling?
Foodborne illness, fines, business closure, or reputational damage.
What are the laws around PHFs in Australia?
They’re governed by the FSANZ Food Standards Code and enforced by state/territory health authorities.
How long can cooked food be left at room temperature?
No longer than 2 hours.
What food safety certificate is required?
A Food Handler Certificate (SITXFSA005) or equivalent.
How do I prevent food poisoning from PHFs?
Control time and temperature, maintain hygiene, and follow storage guidelines.
Conclusion and Key Points
- PHFs need time and temperature control to remain safe.
- Common PHFs include meat, seafood, dairy, eggs, cooked rice, and salads.
- Mishandling PHFs can lead to illness, fines, or closure.
- Training and certification are mandatory for food businesses.
