Norovirus or rotavirus: severe gastro or flu-like symptoms usually begin 24 to 48 hours after exposure and last 1 or 2 days (norovirus) or up to 6 days (rotavirus). E. coli: gastro symptoms usually appear in 3 to 4 days and last about 1 week.
The symptoms of food poisoning usually begin within one to two days of eating contaminated food, although they may start at any point between a few hours and several weeks later. The main symptoms include: feeling sick (nausea) vomiting.
Staph food poisoning is characterized by a sudden start of nausea, vomiting, and stomach cramps. Most people also have diarrhea. Symptoms usually develop within 30 minutes to 8 hours after eating or drinking an item containing Staph toxin, and last no longer than 1 day. Severe illness is rare.
Typically (but not always) food poisoning starts more dramatically with sudden onset of severe symptoms. But viral gastroenteritis can also cause quite severe abdominal pain, and it can make people just as miserable, Saini says.
Most people develop viral gastroenteritis symptoms within 24 to 72 hours of exposure to a virus, while food poisoning symptoms can appear anytime within a few hours to weeks following exposure to a foodborne or waterborne pathogen.
However, the key distinction is time: The symptoms of a stomach bug will take 12 to 48 hours to develop, while the symptoms of food poisoning typically develop much faster, usually with 6 hours of consuming an infected dish. Another common difference between the two is the length of illness.
You may recover in a few days … or not
Most of the time, food poisoning will pass within 12 hours to 48 hours in healthy people. That's how long it takes for a healthy body to purge most foodborne infections. But your length of illness can vary based on several factors.

Clostridium perfringens. Clostridium perfringens is yet another bacteria found in raw meat and poultry that leads to a million more cases of food poisoning every year. It produces a toxin inside your intestines that causes cramps and diarrhea. So there's no vomiting or fever with this infection.
In some cases, adults can take over-the-counter medicines such as loperamide link (Imodium) and bismuth subsalicylate link (Pepto-Bismol, Kaopectate) to treat diarrhea caused by food poisoning.
Symptoms of food poisoning
While different types of pathogenic bacteria can cause different symptoms, food poisoning generally presents itself with symptoms such as nausea, vomiting, diarrhea, abdominal cramping, and fever.
Vomiting usually happens earlier on in the disease, diarrhea usually lasts for a few days, but can be longer depending on the organism that is causing the symptoms.

Symptoms of E. coli O157 infection include severe diarrhea (often bloody) and abdominal cramps. Most people infected with E. coli O157 do not have a fever or vomiting.
