Deli Prawns Trigger Illness - Prawns from deli, Taree New South Wales

Manning Street, Taree, 2430 New South Wales, Australia

I bought a kilo of prawns from the deli. They started with a V.
I ate some then half an hour later felt crook in the stomach and I had diarrhea a couple of times in the span of 2 hours. I didn’t think anything of it.
At 6:30 I had prawns again on my steak and then about 45 minutes later I vomited for about 5 minutes. I feel extremely nausea and crook. I think those prawns weren’t good. | Symptoms: Nausea, Diarrhea, Vomiting
