What did sickness did i get?

me and my dad went for a meal. i got a BBQ chicken pizza. i had it and straight away need to poop. then again. and again. i did my stuff and then had a nutty sickness in my throat. we went home and i felt cold (it was during the heat wave) and a sore tummy. i went to sleep for about 2 hours. then suddenly work up, went to the bath room and threw up. what happened to me? the chicken was pale white on the outside (i didn't check the inside). thanks :)
