Another pedantic post pertinent to poop - you can get sick with amoebiasis, or amoebic dysentery a few days after eating the Bad Food, but the incubation period is usually 2-4 weeks.

Coulda been Clostridium perfringens at 6 - 12 hours, Staph poisoning at 1 - 6 hours or Bacillus cereus (8 - 12 hours but the vomiting part can happen at 2 - 4 hours). That last one is found in starchy foods like rice, pasta and potatoes and gets to sick-making levels when the food is left at room temperatures.
