UK Health Radio Podcast
Dr. Dean Mitchell talks with Dr. Thomas Platts-Mills about alpha-gal syndrome, a tick-related allergy to red meat, using a fatal pilot case to show how easily it can be missed and how careful testing can reveal the true cause. The discussion covers delayed reactions, key lab markers, co-factors such as alcohol, and what this all means for people living in tick-heavy areas.

How Tick Bites Turned Steak Into a Deadly Allergy
Episode Overview
- Delayed abdominal pain after eating red meat, especially in people with tick bites, may point to alpha-gal syndrome rather than simple food poisoning.
- Standard post-mortems often miss anaphylaxis, so specific blood tests for IgE to alpha-gal, total IgE and tryptase can be crucial for diagnosis.
- Low alpha-gal IgE levels can still be significant if they form a high proportion of the total IgE, especially in people without other allergies.
- Alcohol, NSAIDs, menstrual cycle and exercise can increase food absorption and make alpha-gal reactions more severe.
- IgE to alpha-gal can decrease over time, and some patients later tolerate red meat again, but this should be approached cautiously with medical guidance.
“"An undesigned post-mortem doesn't routinely identify anaphylaxis."”
Ever wondered what it takes to turn a baffling medical mystery into a clear diagnosis? This conversation between Dr. Dean Mitchell and allergist-immunologist Dr. Thomas Platts-Mills centres on alpha-gal syndrome – a delayed allergy to red meat triggered by tick bites – and the shocking case of a seemingly healthy airline pilot whose steak dinner ended his life. You’ll hear Dr.
Platts-Mills explain how he went from barely knowing what allergy meant in medical school to piecing together this unusual condition through careful lab work and clinical detective work. He links clusters of cases across the southern United States to tick populations, and shows how reactions to the cancer drug cetuximab first hinted that a sugar molecule, alpha-gal, was the culprit.
The episode walks through the pilot’s story in detail, showing how severe abdominal pain after barbecues was misread as food poisoning, and how routine post-mortems “don’t routinely identify anaphylaxis”, leaving families without answers. It’s a stark reminder that serious allergic reactions don’t always look like the classic rapid-onset breathing problems many expect.
For anyone interested in health during sobriety, there’s a striking segment on how alcohol, exercise and common painkillers can intensify alpha-gal reactions by increasing food absorption, and why some people may have hives only while others collapse with life-threatening drops in blood pressure. There’s also practical talk: the role of blood tests for IgE to alpha-gal and total IgE, why even low numbers can matter, and how levels can fall over time so some people cautiously reintroduce red meat.
Along the way, Dr. Platts-Mills mixes serious science with dry humour, including admitting, “I’m a real scientist” who collected 200 seed ticks on himself and later developed hives after lamb chops and red wine. If you’ve ever had unexplained reactions after meat, or live in tick-heavy areas, this episode may leave you asking new questions about your symptoms – and about what’s really on your plate.
