The symptom I chose was salmonella and you get it when you eat contaminated foods such as eggs,meats,etc.
When you get salmonella poisoning you are at risk and the symptoms can be vomiting,fever,diarrhea,and abdominal cramps.
Salmonella is not very dangerous but it can mess with some people pretty bad.But it is very easy to prevent all you have to do is make sure your food items are cooked and done and make sure raw meats don't touch anything that your using for something else.
The incubation period for the symtom salmonella is 12-72 hours.
