Introduction
Foodborne illness, also known as food poisoning, remains a major yet preventable public health issue in Australia. Whether at home, in cafés, or in workplaces, unsafe food handling can cause serious illness and even hospitalisation. This guide explains what foodborne illness is, what causes it, how it spreads, and — most importantly — how to prevent food poisoning using safe food handling practices aligned with Australian food safety standards.
What Is Foodborne Illness?
Definition and Overview
Foodborne illness refers to diseases caused by eating contaminated food or drinks. Contamination can occur from bacteria, viruses, parasites, or chemicals.
According to the World Health Organization (WHO) and Food Standards Australia New Zealand (FSANZ), it is a significant public health concern, causing thousands of cases each year.
Anyone can be affected, especially people preparing or consuming food in workplaces such as restaurants, cafés, offices, or schools.
Foodborne Illness vs. Food Poisoning
The terms are often used interchangeably, but food poisoning usually describes short-term illness from contaminated food, while foodborne illness includes a wider range of diseases caused by different pathogens or toxins.
What Causes Foodborne Illness in Australia?
Common Pathogens
- Salmonella – Found in raw eggs, poultry, and unpasteurised milk.
- E. coli – Linked to undercooked meat and contaminated produce.
- Listeria monocytogenes – Can grow in refrigerated food; risky for pregnant women.
- Norovirus – Highly contagious and spread by infected hands.
- Campylobacter – Common in undercooked chicken and unclean water.
Unsafe Food Handling Practices
Risky behaviours that lead to contamination:
- Poor hand hygiene before and after food prep
- Using dirty utensils or chopping boards
- Not separating raw and cooked food
- Failing to sanitise kitchen surfaces
Contaminated Ingredients or Water
- Produce washed with dirty water
- Meat from infected animals
- Using expired or spoiled ingredients
Symptoms of Foodborne Illness
Early Signs
- Nausea
- Vomiting
- Diarrhoea
- Abdominal cramps
- Mild fever
Symptoms can appear within a few hours or up to several days after eating contaminated food.
Severe Reactions
Seek medical help if you experience:
- Dehydration (especially for children or elderly)
- Persistent vomiting or diarrhoea
- High fever above 38.5 °C
- Blood in stool

How Does Foodborne Illness Spread?
Cross-Contamination
Occurs when bacteria transfer from one item or surface to another, for example:
- Using the same knife for raw chicken and salad
- Reusing chopping boards without cleaning
- Touching ready-to-eat food with contaminated hands
Improper Storage and Cooking
Bacteria thrive between 5 °C and 60 °C — the “danger zone.”
Avoid:
- Leaving food unrefrigerated for long periods
- Undercooking poultry or meat
- Storing raw meat above cooked food
Treatment and Recovery
Home Care
Most mild cases clear up on their own.
- Stay hydrated with oral rehydration solutions
- Rest and eat bland foods once symptoms ease
- Avoid dairy, caffeine, and alcohol until fully recovered
When to See a Doctor
Seek medical attention if:
- Symptoms last longer than 48 hours
- You’re pregnant, elderly, or immunocompromised
- You notice blood in vomit or stool
