Food Poisoning Symptoms\nNov. 24, 2025\n\nFor Everyone\n\n## Key points\n- Symptoms of food poisoning depend on the type of germ you swallowed.\n- The most common symptoms include diarrhea, stomach pain or cramps, nausea, vomiting, and fever.\n- Severe food poisoning can cause bloody diarrhea, diarrhea that lasts more than 3 days, fever over 102°F, frequent vomiting, and dehydration.\n\n![Person holding their stomach in pain, shape of stomach outlined in red](https:\/\/www.cdc.gov\/food-safety\/media\/images\/2024\/06\/GettyImages-1052976746-16x9-1.jpg)\n\n## Symptoms\nYou can get sick with food poisoning after swallowing certain germs, like *Salmonella* or *E. coli*. Your symptoms may vary, depending on the germ you swallowed. Symptoms can range from mild to serious and can last for a few hours or several days. Some germs can make you sick within a few hours after you swallow them. Others may take a few days to make you sick.\n\nThe most common symptoms of food poisoning are:\n\n- Diarrhea\n- Stomach pain or cramps\n- Nausea\n- Vomiting\n- Fever\n\nIf you have diarrhea or vomiting, be sure to drink plenty of fluids to prevent dehydration (not having enough water in your body).\n\n## Complications and when to seek help\n### Seek help\nSee a doctor if you have any symptoms that are severe, including:\n\n- Bloody diarrhea\n- Diarrhea that lasts more than 3 days\n- High fever (temperature over 102°F)\n- Vomiting so often that you cannot keep liquids down\n- Signs of dehydration, which include not urinating (peeing) much, a dry mouth and throat, and\/or feeling dizzy when standing up\n\n### If you are pregnant\nSee your doctor if you are pregnant and have a fever and other flu-like symptoms. Some mild infections can cause problems with pregnancy.\n### Complications\nMost people have mild illnesses, but some infections spread by food are serious or even life-threatening. Some people may need to be hospitalized, and some illnesses lead to other health problems, including:\n\n- [Meningitis](https:\/\/www.cdc.gov\/meningitis\/about\/fungal-meningitis.html)\n- Kidney damage\n- [Hemolytic uremic syndrome](https:\/\/www.cdc.gov\/ecoli\/signs-symptoms\/hus.html) (HUS), which can cause kidney failure\n- [Arthritis](https:\/\/www.cdc.gov\/arthritis\/index.html)\n- Brain and nerve damage\n\nFor some people, these health problems can last for weeks or months after recovering from a foodborne illness. For others, they never go away.\n\n## Symptoms by germ\nSome germs can make you sick within a few hours after you swallow them. Others may take a few days to make you sick. This table provides details about the symptoms caused by different germs, when they usually start, and common sources for those germs.

# Food Poisoning Symptoms Nov. 24, 2025 For Everyone ## Key points - Symptoms of food poisoning depend on the type of germ you swallowed. - 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. ![Person holding their stomach in pain, shape of stomach outlined in red](https://www.cdc.gov/food-safety/media/images/2024/06/GettyImages-1052976746-16x9-1.jpg) ## Symptoms You can get sick with food poisoning after swallowing certain germs, like Salmonella or E. coli. Your symptoms may vary, depending on the germ you swallowed. Symptoms can range from mild to serious and can last for a few hours or several days. Some germs can make you sick within a few hours after you swallow them. Others may take a few days to make you sick. The most common symptoms of food poisoning are: - Diarrhea - Stomach pain or cramps - Nausea - Vomiting - Fever If you have diarrhea or vomiting, be sure to drink plenty of fluids to prevent dehydration (not having enough water in your body). ## Complications and when to seek help ### Seek help See a doctor if you have any symptoms that are severe, including: - Bloody diarrhea - 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, and/or feeling dizzy when standing up ### If you are pregnant See your doctor if you are pregnant and have a fever and other flu-like symptoms. Some mild infections can cause problems with pregnancy. ### Complications Most people have mild illnesses, but some infections spread by food are serious or even life-threatening. Some people may need to be hospitalized, and some illnesses lead to other health problems, including: - [Meningitis](https://www.cdc.gov/meningitis/about/fungal-meningitis.html) - Kidney damage - [Hemolytic uremic syndrome](https://www.cdc.gov/ecoli/signs-symptoms/hus.html) (HUS), which can cause kidney failure - [Arthritis](https://www.cdc.gov/arthritis/index.html) - Brain and nerve damage For some people, these health problems can last for weeks or months after recovering from a foodborne illness. For others, they never go away. ## Symptoms by germ Some germs can make you sick within a few hours after you swallow them. Others may take a few days to make you sick. This table provides details about the symptoms caused by different germs, when they usually start, and common sources for those germs. Search the table for symptoms you are having.
