Chicken Sub Illness Alert - Subway, England

SE1 England, United Kingdom

Went to subway, ate a chicken bacon and cheese sub, the symptoms started later that night (17/02/2016) only mild so I brushed them off, last night was by far my worst night 19/02/2016 to the early hours of 20/02/2016, I had a fever of 39 1/2 reaching 40 at times, I was hallucinating and dizzy and confused, the reason why I know that it was the subway is due to the fact my pregnant friend had milder symptoms of food poisoning and it's the only food we have ate together this week. | Symptoms: Diarrhea, Nausea, Fever, Dizziness
