Introduction
Food allergies are more than just an inconvenience—they can be life-threatening. In Australia, where food culture is diverse and workplaces often include shared kitchens and team meals, understanding how to manage and respond to food allergies is essential. This guide provides practical, medically accurate, and workplace-relevant information to help Australians navigate food allergy risks with confidence.
What Are Food Allergies?
Food Allergy vs Food Intolerance
Food allergies involve the immune system. When someone with a food allergy eats a trigger food, their immune system mistakes it for something harmful and responds by releasing chemicals like histamine. This can result in symptoms ranging from mild to life-threatening (anaphylaxis).
By contrast, a food intolerance doesn’t involve the immune system. It usually affects the digestive system and may cause symptoms like bloating, diarrhoea, or discomfort. For example, lactose intolerance results from an inability to digest lactose, not from an immune reaction.
Prevalence in Australia
According to Healthdirect, food allergies are on the rise in Australia. While they are more common in children, an increasing number of adults are being diagnosed—especially in workplace environments with shared food spaces like staff rooms and corporate kitchens.
In fact, 1 in 10 infants and about 2% of adults in Australia have a food allergy, making workplace safety and awareness critical.
Common Food Allergens in Australia
Top Food Allergens
Australia recognises nine major food allergens that must be declared on food labels:
- Peanuts
- Tree nuts (e.g. almonds, cashews)
- Milk
- Eggs
- Fish
- Shellfish
- Wheat
- Soy
- Sesame
These allergens are responsible for the majority of serious allergic reactions in Australia. Even tiny traces can trigger symptoms in highly sensitive individuals.
Cross-Reactivity and Hidden Allergens
Cross-reactivity occurs when someone allergic to one food reacts to another with a similar protein structure—like someone allergic to birch pollen reacting to apples. Cross-contact, on the other hand, happens when allergen-containing foods come into contact with allergy-safe food, often in shared kitchens or food prep areas.
Hidden allergens are also a concern. Common sources include:
- Sauces and dressings (e.g. soy, fish sauce)
- Packaged snacks labelled “may contain traces”
- Foods fried in the same oil as allergens
Signs and Symptoms of a Food Allergy
Mild and Moderate Reactions
Mild and moderate symptoms can occur within minutes to hours after exposure and may include:
- Itchy skin or hives
- Redness or rash
- Swelling of lips or face
- Stomach pain, nausea, or diarrhoea
For instance, an employee may experience itchy lips and abdominal cramps after eating a salad containing undisclosed sesame seeds.
Severe Allergic Reactions (Anaphylaxis)
Anaphylaxis is a medical emergency. Symptoms include:
- Difficulty breathing
- Swelling of the tongue or throat
- Dizziness or collapse
- Pale or bluish skin
Without prompt treatment, anaphylaxis can be fatal. Always treat it as an emergency.
Diagnosing a Food Allergy
Medical History and Allergy Testing
Diagnosis typically starts with a GP consultation, who may refer patients to an allergist. Common diagnostic tools include:
- Skin prick tests – a small amount of allergen is introduced to the skin
- Blood tests (IgE tests) – check for allergy-related antibodies
- Elimination diets – removing suspected allergens
- Oral food challenges – monitored consumption of the suspected food
When to See a Specialist
See a specialist if you:
- Experience recurring symptoms after eating certain foods
- Have family members with allergies or asthma
- Work in an environment with potential allergen exposure (e.g. hospitality, education)
In Australia, allergy referrals are usually bulk billed under Medicare.
Emergency Response to Allergic Reactions
Using an EpiPen
An EpiPen (adrenaline autoinjector) is the first line of treatment for anaphylaxis. Here’s how to use it:
- Remove the blue safety cap
- Hold firmly, orange tip down
- Press the orange tip into the outer mid-thigh
- Hold for 3 seconds
- Call 000 immediately
Visit ASCIA’s EpiPen training page for demonstration videos.
First Aid and When to Call 000
If someone shows signs of anaphylaxis:
- Use the EpiPen immediately
- Call 000
- Lay them flat and elevate legs (unless breathing is difficult)
- Do not allow them to stand or walk
Even if symptoms improve, emergency care is still required.
Managing Food Allergies in Daily Life
Reading Food Labels
In Australia, food labelling laws require allergens to be clearly listed. Watch for:
- Bolded allergens in ingredient lists
- “May contain traces of…” (indicates possible cross-contamination)
- Advisory statements like “made in a facility that also processes…”
Cooking and Meal Preparation
To avoid cross-contact:
- Use separate chopping boards and utensils
- Wash hands thoroughly
- Store allergen-free food separately
- Clean shared surfaces before preparing allergy-safe meals
Eating Out Safely
- Inform staff about your allergy clearly
- Ask how meals are prepared and what oils are used
- Avoid buffets or self-serve where cross-contact is likely
Restaurants in Australia are encouraged to follow FSANZ allergen labelling and safety guidelines.
Food Allergies in the Workplace
Employee Safety and Communication
If you have a food allergy:
- Inform HR or your direct supervisor
- Label your food clearly in shared fridges
- Bring your own utensils if needed
- Avoid communal snacks without ingredients listed
Clear communication helps foster an inclusive and safe environment.
Employer Responsibilities
Employers have a duty of care under Australian WHS laws to ensure a safe working environment. This includes:
- Training staff on recognising allergic reactions
- Providing access to first aid and EpiPens
- Displaying emergency contact protocols
- Creating allergy-safe kitchen policies (e.g. no peanut zones)
Living With Food Allergies: Mental Health and Support
Managing Anxiety Around Food
Living with food allergies can trigger fear and social anxiety, especially when eating out, travelling, or attending events. Tips include:
- Carry your EpiPen and action plan
- Plan meals ahead
- Practice assertive communication about your needs
Support Networks and Resources
Support is available via:
- Allergy & Anaphylaxis Australia (allergyfacts.org.au)
- Local allergy support groups
- Psychologists with experience in chronic illness anxiety
- GP referrals for mental health plans (covered by Medicare)
Prevention and Future Outlook
Can Food Allergies Be Outgrown?
Some allergies, like egg or milk, are often outgrown by age 5–10. Others, like peanut or shellfish, are more likely to persist into adulthood. Regular reviews with a specialist are recommended.
Desensitisation and Immunotherapy
Oral Immunotherapy (OIT) and desensitisation therapies are emerging treatments that involve gradually introducing small amounts of allergens under medical supervision.
In Australia, these are available in select clinics and often part of clinical trials.
