What is Food Safety?
Food safety refers to the proper handling, preparation, and storage of food to prevent foodborne illnesses. According to the World Health Organization (WHO), food safety encompasses everything from hygienic food handling to correct cooking temperatures and safe storage conditions. In Australia, organisations like Food Standards Australia New Zealand (FSANZ) and state-based authorities ensure food sold and consumed is safe and fit for human health.
Safe food practices are essential not just for public health, but also for maintaining trust in food businesses and institutions.
The Risks of Poor Food Handling
Improper food handling can lead to serious foodborne illnesses, including salmonella, listeria, and campylobacter infections. Australia has experienced notable outbreaks due to poor handling—for example, the 2018 listeria outbreak linked to rockmelons.
These illnesses can cause severe symptoms and, in vulnerable populations like children, the elderly, or immunocompromised individuals, may lead to hospitalisation or death. Unsafe practices in workplaces—especially in aged care or hospitality—can also lead to fines, reputational damage, and loss of business licences.
Key Principles of Safe Food Handling
Personal Hygiene for Food Handlers
Personal hygiene is a cornerstone of food safety. As outlined by the NSW Food Authority, food handlers must:
- Wash hands thoroughly with soap and warm water before handling food, after using the toilet, touching raw food, or sneezing.
- Wear clean, protective clothing (e.g. aprons, gloves, hairnets).
- Report any illness to supervisors and avoid food prep when sick.
Cleaning and Sanitising Surfaces and Equipment
Cleaning removes dirt and food particles; sanitising kills bacteria. Food prep areas must be cleaned and sanitised regularly using approved sanitisers. Key steps include:
- Wash with detergent and hot water.
- Rinse and air dry or use clean cloths.
- Apply food-grade sanitiser, especially on high-touch surfaces.
Avoiding Cross-Contamination
Cross-contamination occurs when harmful bacteria transfer from raw to ready-to-eat foods. To prevent it:
- Use colour-coded chopping boards and knives.
- Store raw meat separately, ideally on bottom shelves.
- Avoid touching cooked foods with utensils used for raw items.
Safe Food Storage and Temperature Control
The Danger Zone and Temperature Guidelines
The temperature danger zone for food is between 5°C and 60°C, where bacteria multiply rapidly. To stay safe:
- Keep cold foods below 5°C.
- Keep hot foods above 60°C.
- Limit the time food spends in the danger zone to under 2 hours.
Proper Refrigeration and Freezing
- Store food in clean, sealed containers.
- Do not overfill the fridge—allow air to circulate.
- Freeze foods promptly and thaw in the fridge, microwave, or under cold running water—not on the counter.
- General guidelines: raw poultry lasts 1–2 days in the fridge, leftovers up to 3 days, and frozen meat up to 6 months.
Labelling and Use-by Dates
Understanding food dates helps reduce waste and protect health:
- Use-by dates relate to safety. Do not eat food past this date.
- Best-before dates relate to quality. Food is often safe to eat afterward, but quality may decline.
- Implement the FIFO (First In, First Out) system to rotate stock efficiently.
Safe Food Preparation Practices
Preparing Raw Meat, Poultry, and Seafood
- Always wash hands after handling raw meat.
- Use separate utensils for raw and cooked foods.
- Keep cutting boards and knives sanitised.
- Never wash raw poultry, as this can spread bacteria via water droplets.
Washing Fruits and Vegetables Correctly
- Rinse under running water.
- Use a soft brush for items like potatoes or melons.
- Do not use detergents or bleach on produce.
Cooking to Safe Temperatures
Cooking food to the correct internal temperature is critical. According to FSANZ:
- Poultry: 75°C
- Minced meat and sausages: 70°C
- Eggs (runny yolks): 63°C
- Leftovers: Reheat to at least 75°C
Use a food thermometer to check temperatures, especially in commercial kitchens.
Legal Obligations and Food Safety Certification in Australia
Food Safety Standards and Legislation
Australia’s primary regulations include:
- Australia New Zealand Food Standards Code
- State-specific laws (e.g. NSW Food Act 2003, Food Act 2006 QLD)
- Local council inspection requirements
Food businesses must ensure that all staff understand and comply with relevant legislation.
Food Handler Training and Certification
A food handler is anyone involved in food prep, storage, or service. Training is essential to meet legal obligations. Workers can complete accredited training through organisations offering a food safety course like SITXFSA005, ensuring proper knowledge of hygiene and safety principles.
The Role of a Food Safety Supervisor
Required in many businesses, a Food Safety Supervisor (FSS) has extra responsibilities:
- Ensures staff comply with regulations.
- Maintains records and responds to breaches.
- Must complete approved FSS training (e.g. in NSW, Queensland, and Victoria).
Common Food Safety Mistakes to Avoid
Reusing Gloves or Equipment Without Cleaning
Gloves are not a substitute for handwashing. Change gloves between tasks and sanitise equipment after each use to prevent contamination.
Improper Cooling or Reheating of Food
- Cool food rapidly (e.g. in shallow containers).
- Don’t leave food out for more than 2 hours.
- Reheat food thoroughly to 75°C before serving.
Not Checking for Allergens or Labelling Mistakes
- Always check packaging and labels.
- Prevent allergen cross-contact by using separate equipment.
- Clearly identify common allergens (e.g. peanuts, gluten, dairy).
Food Safety in Different Environments
Commercial Kitchens and Cafés
- Conduct regular temperature checks.
- Clean and sanitise surfaces between shifts.
- Keep records of cleaning schedules and staff training.
Aged Care, Childcare and Health Facilities
Vulnerable individuals need stricter standards:
- Use pasteurised products.
- Avoid raw sprouts and undercooked eggs.
- Maintain strict temperature logs.
Home Kitchens and Packed Lunches
- Pack perishable items with ice bricks.
- Store leftovers quickly.
- Label containers with dates and contents.
Promoting a Culture of Food Safety
Food Safety Checklists and SOPs
Tools like iAuditor help maintain daily safety standards. Standard Operating Procedures (SOPs) ensure consistent practices in cleaning, cooking, and storing food.
Continuous Training and Awareness
- Schedule regular refresher training.
- Display hygiene signage.
- Encourage staff to speak up about potential safety breaches.
Frequently Asked Questions (FAQ)
