Most people fully recover from the most common types of food poisoning within 12 to 48 hours. Some types of food poisoning can cause serious complications.
Replace fluids with water, sports drinks, juice with added water or broths. Children or people at risk for serious illness should drink rehydration fluids (Pedialyte, Enfalyte, others). Talk to your doctor before giving rehydration fluids to infants. Ease back into eating.
Symptoms of food poisoning can appear anywhere between four hours and one week after ingesting a contaminated food item, and can persist for as short a time as 24 hours or as long as a week. This variability in both onset and duration of symptoms is another reason food poisoning so often goes unidentified.
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 within 6 hours of consuming an infected dish. Another common difference between the two is the length of illness.
Diarrhea that lasts more than 3 days. High fever (temperature over 102°F) Vomiting so often that you cannot keep liquids down. Signs of dehydration, which include not urinating (peeing) much, a dry mouth and throat, feeling dizzy when standing up.
Over-the-counter medicines. 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. These medicines can be dangerous for infants and children.
Myth: Leftovers are safe to eat if they look and smell okay.
Fact: Most people would not choose to eat spoiled, smelly food. However, if they did, they would not necessarily get sick. This is because there are different types of bacteria – some cause illness in people and others don't.
Eating a spoiled food is often harmless. Sometimes, it can cause mild vomiting or diarrhea. Serious symptoms are rare. Safest plan: Throw out spoiled or moldy foods.

Most people will recover without intervention in a day or two. If you or someone in your care has a particularly severe reaction to food poisoning, you might need medical intervention. The most common reason for this is dehydration, especially in children.
Salmonella can cause salmonellosis and typhoid fever and paratyphoid fever. Botulism is most often caused by Clostridium botulinum. Some other germs that cause foodborne illness include Cryptosporidium, Cyclospora, hepatitis A virus, Shigella, and Yersinia.
Food poisoning doesn't just come on faster than the stomach flu — it also runs its course more quickly. Dr. Ford says viral gastroenteritis generally lingers for two days, although sometimes, it can last longer. In contrast, food poisoning “hopefully is going to be out of your system sooner than that,” Dr.
Food poisoning symptoms can last a few hours to a few days. How long food poisoning lasts depends on which microorganism infected you. After you ingest contaminated food or beverage, it may take hours or days until you develop symptoms. Here are some time frames for common causes of food poisoning.

Symptoms of food poisoning often include upset stomach, diarrhea and vomiting. Symptoms usually start within hours or several days of eating the food. Most people have mild illness and get better without treatment.
Cramps in your stomach and gut, diarrhea, and vomiting may start as early as 1 hour after eating tainted food and as late as 10 days or longer. It depends on what is causing the infection.
There's often no specific medical treatment for viral gastroenteritis. Antibiotics aren't effective against viruses. Treatment first involves self-care measures, such as staying hydrated.
People who may have a stomach virus but are not experiencing vomiting or diarrhea may get better on their own without treatment. It is still advisable to stay hydrated during this time. However, a person should talk with a doctor if they develop any of the following symptoms: severe pain.
