We ordered it on night of 5th January and had chow mein, walnuthoneyshrimp and beef Shanghai. All 4 of us ate the chow mein. My daughter started vomiting at around midnight and I started having cramping and diarrhoea shortly after. My daughters vomiting continued into the night and she also had diarrhoea around 3am. I had several bouts of diarrhoea during the night and then the vomiting started at around 3:30am. My son started vomiting at 8am and again at 8:30am. He too then had bouts of diarrhoea from 9:30am to around 4pm. My husband got his symptoms on the night of the 7th. He started vomiting at midnight and had diarrhoea immediately after. This continued on into the night and stopped around 5am.
