I am currently vomiting after having sushi?

Gastroenteritis?: You may be starting to get gastroenteritis. How long ago did you eat the sushi? Remember, sushi contains bacteria which we hope are eradicated by proper preparation of the food. But that's not always the case. Or, bacteria can be on the hands of those serving the food. You may get diarrhea. If your symptoms become violent, see a doctor right away.
