Pregnancy Concerns: Fast Food - Burger King, Matfield England

Blue Boys Roundabout, Matfield, TN12 7HE England, United Kingdom

Via the drive thru i ordered Halloumi Burger (no bacon), small fries and chocolate milkshake at about 14:00 on 7th October 2020.
Everything tasted OK, chips were cold but I had driven for 10mins after ordering.
Felt ill about 16:30 and then severe cramping in abdominal area, followed by vomiting and diarrhoea until 02:00. As I am pregnant I was very concerned it might be listeria poisoning. | Symptoms: Nausea, Diarrhea, Vomiting, Stomach Pain, Cramps
