Avocado Sandwich Illness - The Plant Café Organic, San Francisco California

173 Airport Access Road, San Francisco, 94128 California, United States

My wife and I ate here this morning (Friday Feb 28, 2020), before a flight. We didn't eat anything else today, so it was reasonably easy to determine the cause of her food poisoning.
I ate a Caesar Chicken Wrap, and was not ill.
My wife ate a Chicken and Avocado Sandwich, and experienced food poisoning.
Food consumed around 10:30am SF time, and symptom started around 3:00pm SF time, on our way back from the airport. Severe stomach pain and diarrhoea by 3:30pm, followed by nausea and vomiting. Vomiting and retching continued after stomach was empty. | Symptoms: Diarrhea, Nausea, Vomiting, Stomach Pain
