How to prevent food poisoning right when you know it happened

Hi folks might be a stupid question I’ve ate an insane amount of street food down here in México and recently I went to a night market for Christmas and ate tacos. I ate there before and it was good so I went again and I had 3 pastor tacos and they felt off. Later that night my stomach went to hell basically and the next morning I was bed ridden for 5 days with severe food poisoning. I’m better now but is there a way to prevent it once I know it happened? Like if I threw up right after eating the tacos would this not have happened? Let me know, cheers.
