Airport Sandwich Causes Illness - Auf die Hand, Berlin Berlin

Flughafen Tegel, Berlin, 13405 Berlin, Germany

I ate a sandwich 3.7.2019 in the morning and got sich ~6 hours later. Before that I had last eaten the evening before and after that nothing before nausea and vomiting started. I drank only botled water and botled orange juice, so see no other possible reason. | Symptoms: Fever, Nausea, Vomiting
