Big Mac Illness: Nausea, Fever - McDonald's, Santa Catarina

3000 BR-470, 89070-200 Santa Catarina, Brazil

On 02/01/2023 my mother and I had lunch on a Big Mac. My mother already started to feel sick in the afternoon, around 16:30. It turns out that at dawn we both woke up feeling very sick. My mom has diarrhea and I'm very nauseous. Now it's 18:10 on 03/01/2023, and I have a fever while my mom has a headache. We know that the cause is the snack because only my mother and I ate and felt sick. My father who ate lunch elsewhere doesn't have any symptoms, just me and my mom. | Symptoms: Nausea, Diarrhea, Vomiting, Fever, Headache
