We ate a homemade paella with chorizo, prawns and scallops. My partner purchased prawns and scallops from there. He made a paella which we both ate at around 3pm. He had severe sickness and diarrhoea at 6.30pm.
18.30 - 3 hours after eating scallops, I ate the same meal and have no symptoms.  | Symptoms: Diarrhea, Nausea, Vomiting
