Yes, My Boyfriend , My Daughter And I Were All

Yes, my boyfriend , my daughter and I were all sitting here eating, and after words my daughter and I were cleaning up when out of the blue he says "I'm not feeling so well and he laid down. After about 10 min of laying there he said he felt like he was going to get sick so I hurried, getting the trash can over to him just at the right time. He has been sitting on the edge of our bed for the past 30 minutes throwing up and falling asleep while sitting up, because he says he can't lay down or he will get sick even more. He also has the cold sweats really bad to where his shirt is really wet and I have been wiping him down with a towel which has become pretty damp. I have checked him a couple of times or a fever, and when I do he is very cold to the touch. I was thinking that maybe the food we ordered caused him to get food poisoning. The reason I thought I thought it was food poisoning was for one because of the symptoms and for two because I noticed when eating my meal, the ribs we ordered weren't completely done. What do you think this may be the cause of and should I take him to the local emergency room?
