Fatburger Unclaimed

I got extremely sick a few hours after consuming the impossible burger, it turns out that there is a ingredient in it that makes a lot of people sick, but the two other people with me who had the same thing were fine | Symptoms: Diarrhea, Vomiting, Other See Less

I think it was the hamburgers that we ordered. We both got sick within 6 to 7 hours last night. Not wanting to get money back. Just want to make you aware of it.
My Wife and I and Son went here and ordered hamburgers around 12:30... See More PM yesterday.
I had also part of my wife’s hamburger and we both got sick within six hours of eating it. I’ve been throwing up all night. My wife is also throwing up with major diarrhea..
My son ordered an egg on his burger and they had to go to Raleys in the sent her to pick it up and I think our hamburger sat out because the bread was also stale. In addition, My Wife ordered bacon.
We still feel very nauseous and have diarrhea really bad.
