The first signs of food poisoning often include sudden nausea, vomiting, diarrhea (potentially watery or bloody), and stomach cramps/pain, usually starting within hours to a few days after eating contaminated food, along with feeling generally unwell, tired, achy, or having chills and a fever. These symptoms signal your body is fighting germs like bacteria or viruses from the food, with dehydration being a major concern, requiring plenty of fluids.
The most common symptoms include diarrhea, stomach pain or cramps, nausea, vomiting, and fever. Severe food poisoning can cause bloody diarrhea, diarrhea that lasts more than 3 days, fever over 102°F, frequent vomiting, and dehydration.
Q: How can I tell if it's food poisoning or a stomach bug? Food poisoning often comes on quickly—usually within a few hours after eating contaminated food. A stomach bug (viral gastroenteritis) usually develops more gradually, with symptoms appearing 1–2 days after exposure to an infected person or surface.
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.

Should I take Imodium for food poisoning?
Adults who have loose stools that aren't bloody and who have no fever may take loperamide (Imodium A-D) to treat diarrhea. They also may take bismuth subsalicylate (Pepto-Bismol, Kaopectate, others) to treat an upset stomach. These are medicines you can get without a prescription. They are not for children.
Salmonella can also cause typhoid fever. It can spread to other parts of the body. Symptoms of a salmonella infection usually include diarrhea, fever, abdominal cramps, chills, headache, nausea, or vomiting. Treatment may not be needed unless dehydration happens or the infection doesn't get better.
“Start with easy-to-digest and soft foods, like scrambled eggs, almond butter on a banana, or peanut butter toast,” says Stuart. Pairing protein-rich foods such as nut butters with bananas or toast can help balance blood sugar and keep you feeling full longer, Stuart explains.
Some high-risk foods include deli meat, raw milk and produce like leafy greens, cucumbers and onions. To reduce your risk of getting foodborne illness, take steps like washing and cooking food thoroughly.
They list “The Big 6” pathogens (Norovirus, Nontyphoidal Salmonella, Salmonella Typhi, E. coli, Shigella, and Hepatitis A) as being highly infectious, able to cause severe disease in small quantities, and each will be featured individually in this series of articles.
coli is more likely to be spread through contact with infected individuals or animals, while Salmonella is more commonly spread through contaminated food and drinking water. E. coli is generally less severe than pathogens such as Listeria or Salmonella.
Remember this general rule of thumb when you have leftovers. ✅ You have 2 hours to get food into the fridge. ✅ It's safe in the fridge for 2 days. ✅ If you're not going to eat it after that, move it to the freezer and eat within 2 months.
A peanut butter and jelly (PB&J) sandwich is the food associated with adding 33 minutes to your healthy life, according to a University of Michigan study using the Health Nutritional Index (HENI), which measures the minutes of healthy life gained or lost per serving. The study found that nutrient-dense foods like fruits, vegetables, nuts, legumes, and seafood add minutes, while processed items like hot dogs subtract them, with PB&J being a standout for its positive impact due to healthy fats and antioxidants.
Can one person get food poisoning and not the other?
Food poisoning can affect one person or a group of people who all ate the same food. It is more common after eating at picnics, school cafeterias, large social functions, or restaurants.
Bacteria like Staph and Bacillus cereus can make you sick quickly, within 1 to 7 hours. These bacteria produce fast-acting toxins in foods (such as meat or dairy for Staph, and starchy foods like rice for B. cereus).
The most significant discovery is that tomato juice is effective in eliminating Salmonella Typhi, its hypervirulent variants and other bacteria that can harm people's digestive and urinary tract health.
Some people with salmonella infection have no symptoms. Most people develop diarrhea, fever and stomach (abdominal) cramps within 8 to 72 hours after exposure. Most healthy people recover within a few days to a week without specific treatment.
