If he's been sick longer than 12 hours he should really budge to the emergency room, he could be getting dehydrated if he can't hang on to anything down.
Take him to the ER at a hospital. They can run tests, and find out what is cause it. Then, they can give him a shot, that will relieve clear up the food posioning.
I had a doomed to failure case of that around three weeks ago, and went to ER. They found out that I be allergic to something in green onions. They give me a shot of something, sent me back home. Two hours following, I was OK. I haven't eat a green onion since then. I also presume I have eat my last green onion, too.
