A recent coronial inquest in NSW has brought national attention to a hidden danger lurking in our bushland and backyards: mammalian meat allergy triggered by tick bites. The tragic death of 16-year-old Jeremy Webb from the Central Coast has highlighted why every Australian needs to understand how to recognise and respond to anaphylaxis.
A Unique and Tragic Case Study
Jeremy Webb was an active, adventurous teenager who loved skateboarding, surfing, and karate. During a camping trip, he consumed red meat for his final meal. Hours later, he experienced what experts believe was a combination of either a severe allergic reaction or anaphylaxis and an acute asthmatic episode. Tragically, Jeremy passed away without ever knowing he had mammalian meat allergy.
What makes this case particularly concerning is that the allergy was only diagnosed posthumously. According to evidence presented at the inquest, Jeremy likely had the condition from childhood, based on his asthma history, multiple tick bites, and previous allergy symptoms after eating red meat. Yet the connection was never made during his lifetime.
This condition is caused by tick bites that sensitise people to alpha-gal, a sugar found in mammalian meat. Unlike typical food allergies that cause immediate reactions, mammalian meat allergy can take up to five hours to manifest after eating red meat. As allergy expert Associate Professor Sheryl van Nunen explained to the inquest, when symptoms begin, they progress rapidly.
The condition is becoming increasingly common. There has been a 40 per cent year-on-year increase in mammalian meat allergy diagnoses in Australia since 2020, with NSW and Queensland experiencing the highest rates (ABC News). The Sydney basin, particularly the Northern Beaches, has become a global hotspot for this condition.
Why Detecting Anaphylaxis is Critical
The delayed nature of mammalian meat allergy makes detection particularly challenging. Unlike bee stings or peanut allergies that trigger immediate reactions, symptoms from red meat consumption can appear two to six hours after eating, often waking people from sleep.
Early recognition of anaphylaxis symptoms can mean the difference between life and death. Signs to watch for include:
- Airway symptoms: Throat tightness, difficulty talking or hoarse voice
- Respiratory symptoms: Difficult or noisy breathing, Wheeze or persistent cough
- Gastrointestinal issues: Severe abdominal pain, nausea, vomiting, or diarrhoea
- Cardiovascular changes: Rapid or weak pulse, dizziness, or loss of consciousness
In cases of mammalian meat allergy specifically, severe abdominal discomfort occurring several hours after consuming beef, pork, or lamb should raise immediate concern. The seemingly innocent timing can lead to misdiagnosis or delayed treatment, as people may not connect their symptoms to a meal eaten hours earlier.
First Aid for Anaphylaxis: Knowledge That Saves Lives
When anaphylaxis occurs, every second counts. Knowing how to respond can save a life. The ANZCOR guidelines recommend that first aiders:
- Lay person flat (if conscious) do NOT allow them to stand or walk
- Prevent further exposure to the triggering agent if possible.
- Administer adrenaline (epinephrine)
- Call 000 immediately
- Be prepared to give a second dose – If symptoms don’t improve after 5 minutes, administer a second adrenaline dose if available
- Monitor and reassure – Stay with the person, monitor their breathing and consciousness
- Start CPR if needed – If the person stops breathing, begin cardiopulmonary resuscitation immediately
Even if symptoms seem to improve after adrenaline administration, the person must go to hospital. Biphasic reactions, where symptoms return hours later, occur in up to 20% of anaphylaxis cases.

Jeremy Webb’s mother, Dr Myfanwy Webb, found some comfort knowing that his story would raise awareness and save other lives. She expressed confidence that the inquest would help prevent similar tragedies.
The reality is that anaphylaxis can happen to anyone, anywhere, at any time. Tick-induced mammalian meat allergy is just one of many potential triggers. With just two tick bites being enough to sensitise most people to this condition, and with 60% of Australians living in tick-prevalent areas, this risk is closer than many realise.
Don’t wait until an emergency strikes to wish you knew what to do. Our comprehensive first aid courses provide hands-on training in recognising and responding to anaphylaxis, using adrenaline auto-injectors, performing CPR, and managing a wide range of medical emergencies.
