Wouldn't you think that if someone was unable to tolerate a certain food, that they would get sick every time that they eat it? Not just a one off experience? There are many types of microbe bacteria that can make a person sick, aka food poisoning. I don't understand why so many of you keep denying that fact. And yes, there are bacteria that brings on illness much quicker then 24 hours. A quick Google search will show you this. Please stop perpetuating the lie that food poisoning can not come on quickly and be done quickly. You do realize that they say "average" for a reason. Some people have worse immune systems or metabolisms so they are likely to suffer longer. There is a quick side the average also. I really don't understand why people like you keep saying that over and over when it is obviously not true. Your mentality is exactly why people, especially woman, have their medical issues dismissed. You want to paint everyone with the same brush when we know that everyone's body works differently.
