What should you know about penicillium allergy foods to avoid?

Penicillium is a group of moulds. Exposure may occur through the environment, spoiled food, or food production, but a reaction to mould in the air is not the same as a reaction after eating a food. Symptoms can include sneezing, congestion, wheezing, hives, vomiting, lip swelling or an itchy throat. Food Allergy and environmental allergy require different questions during assessment.

Do not assume that all cheese, fermented products or foods with a surface mould are unsafe. The relevant trigger depends on the individual product, exposure route and symptoms. Throw away visibly spoiled food as a general food-safety measure, not as a substitute for diagnosis.

Write down the suspected food or environment, how it was encountered, how quickly symptoms began, and whether symptoms affected breathing, skin, digestion or alertness. Bring ingredient labels or photographs when possible. A clinician can decide whether Allergy Testing is useful and whether a supervised food assessment is safe.

Until you have advice, avoid only the suspected trigger if exposure clearly causes symptoms; do not adopt a broad elimination diet without guidance. Ask a pharmacist or doctor before using antihistamines or other treatment, especially for a child or during pregnancy.

Seek emergency help for breathing difficulty, throat or tongue swelling, widespread hives with dizziness, repeated vomiting with weakness, collapse, or rapidly worsening symptoms after an exposure. These can be signs of Anaphylaxis and need immediate treatment; use a prescribed adrenaline injector according to your action plan.

Ask whether the reaction suggests food or environmental allergy, what exposure should be avoided, whether testing is appropriate, and what your emergency plan should contain.
