Food poisoning is caused by vomiting and diarrhea, and often this condition is resolved on its own, while the dehydration or imbalance of electrolytes may develop and your stomach gets upset.

An individual can get clostridium food poisoning due to poor food handling practices in the home, in factories, or in a food outlet, mostly relating to cooking, storage, and refrigeration temperatures.
The symptoms of clostridium food poisoning appear about 12 hours after eating the contaminated (dirty) food and it may include pain, diarrhea, and sometimes nausea and vomiting.

Listeria is an unusual bacterium and it can grow in cold temperatures (such as in the refrigerator). Listeria is found in smoked fish, raw (unpasteurized) cheeses, and ice cream.  An individual with listeria had to face fever, vomiting, and gastrointestinal pain.
