flight from Dublin, Ireland to Newark New Jersey on Saturday November 16, 2019. It was a breakfast food on a United airlines flight. I was the only thing that I ate that the other 2 travelers did not eat., I was traveling with 2 others they did not eat the eggs with sausage. The severe symptons happened within a couple hours since they served that breakfast early on in the flight. The severe symptons started 30 minutes after I got to my other gate for my connecting flight. I started to feel very sick to my stomach, Then I had diarrhea and I vomited many times. I passed out once in the hall way waiting for the bathroom and then passed out in the bathroom and hit the floor. Now I have bruising on my back,bu**ocks and arm.
