Fever and Food Poisoning: Is There a Connection?

Does Food Poisoning Cause Fever

One of the common questions among individuals who suspect they have food poisoning is whether it typically causes a fever. While not all cases of food poisoning involve a fever, it is a possible symptom and one that can indicate a more severe infection.

The presence of fever in food poisoning depends on the type of bacteria or virus causing the infection. Some strains of bacteria, such as Salmonella and Campylobacter, commonly cause fever as part of their symptoms. In contrast, others, like Staphylococcus aureus, typically do not cause a fever. Likewise, viruses such as Norovirus may or may not produce a fever, depending on the individual case.

In addition to the specific type of pathogen, other factors can influence whether fever occurs in food poisoning. The severity of the infection and the affected individual’s overall health can both affect the immune response and likelihood of fever.

If you suspect you have food poisoning and are experiencing a fever, it is crucial to seek medical attention promptly. A healthcare provider can help determine the underlying cause of the fever and provide appropriate treatment to manage the infection and any related symptoms.

Other Common Symptoms of Food Poisoning

In addition to fever, there are several other symptoms that commonly occur in cases of food poisoning. It is important to be aware of these symptoms, as they can help identify the cause and severity of the illness.


One of the most commonly reported symptoms of food poisoning is diarrhea. This is often accompanied by cramping and abdominal pain. Diarrhea can indicate that the body is trying to rid itself of toxins or irritants from contaminated food.


Vomiting is another common symptom of food poisoning, although it is not always present. When it does occur, it is often severe and can lead to dehydration. It is important to stay hydrated when experiencing vomiting, as it can lead to further complications if left untreated.

Abdominal Pain and Cramping

Abdominal pain and cramping are often reported in cases of food poisoning, as the toxins or irritants can cause inflammation in the digestive system. This can be a sign of a more severe illness if the pain is severe and persistent.


Nausea is another common symptom of food poisoning, often occurring alongside vomiting. It can also be a sign of dehydration, as the body tries to rid itself of harmful substances.

It is important to seek medical attention if these symptoms are severe or persistent, as they can indicate a more serious illness. It is also important to stay hydrated and rest while recovering from food poisoning.

Seeking Treatment for Food Poisoning

If you experience symptoms of food poisoning, it is crucial to seek medical attention if:

  • Your symptoms are severe and do not improve after a few days
  • You have a high fever (over 101.5°F)
  • You experience bloody stools
  • You are dehydrated and unable to keep fluids down

Your doctor may recommend medications to treat symptoms such as diarrhea, nausea, and vomiting. In severe cases, hospitalization may be necessary to receive intravenous fluids and antibiotics.

To prevent dehydration, it is essential to drink plenty of fluids and electrolyte solutions. Resting and abstaining from solid food for a few hours will give your digestive system a chance to rest and recover. Afterward, slowly introduce bland, easy-to-digest foods like toast, rice, or bananas. Avoid spicy, fried, or fatty foods that can aggravate your symptoms.

AntibioticsPrescribed by a doctor to treat severe cases and prevent bacterial infections from spreading
Anti-vomiting medicationOver-the-counter medication to reduce nausea and vomiting
ProbioticsHelp to restore and maintain the balance of good bacteria in the gut, which can be disrupted by food poisoning

If you suspect that the food that caused your food poisoning came from a restaurant or food service establishment, report it to your local health department to prevent it from happening to others.

Remember, prevention is always better than cure. Wash your hands thoroughly before preparing or eating food, cook food to the appropriate temperature, and avoid consuming undercooked or raw meat, fish, and eggs.

Recovery and Self-Care Tips for Food Poisoning

If you’ve contracted food poisoning, it’s important to take the necessary steps to recover properly. Follow these self-care tips to ease your symptoms and speed up your recovery:

Stay Hydrated

One of the most important things you can do when recovering from food poisoning is to stay hydrated. Vomiting and diarrhea can cause dehydration, so it’s important to drink plenty of fluids. Stick to clear liquids, such as water and broth, and avoid drinks that contain caffeine or alcohol, which can worsen dehydration.

Follow a Bland Diet

While you’re recovering from food poisoning, it’s best to stick to a bland diet of easily digestible foods. Avoid spicy, fatty, or fried foods, which can aggravate your digestive system. Stick to simple foods like rice, plain toast, and bananas until your symptoms improve.

Get Plenty of Rest

Your body needs time to recover from food poisoning, so it’s important to get plenty of rest. Take time off from work or school and limit your activities until you start to feel better. Resting can help give your body the energy it needs to fight off the infection.

Consider Probiotics

Probiotics are beneficial bacteria that can help improve your digestive health. They’re available in supplement form or in certain foods, such as yogurt and kefir. Talk to your healthcare provider to determine if probiotics are right for you.

By following these self-care tips and allowing your body to rest and recover, you can overcome the symptoms of food poisoning and get back to your normal routine. As always, if your symptoms persist or worsen, seek medical attention.

Preventing Food Poisoning

Food poisoning can be prevented by following some simple guidelines for food handling, cooking, and storage. By taking proper precautions, you can reduce the risk of contamination and keep your food safe to eat.

Wash Your Hands

One of the easiest ways to prevent food poisoning is to wash your hands thoroughly before handling food. This helps to remove harmful bacteria that can cause illness. Use warm water and soap and scrub your hands for at least 20 seconds. Dry your hands with a clean towel or air dry them.

Clean and Sanitize Kitchen Surfaces and Utensils

Make sure all kitchen surfaces and utensils are thoroughly cleaned and sanitized before and after use. Use hot, soapy water to clean cutting boards, knives, and other utensils, and then rinse them with hot water. Sanitize them by using a solution of 1 tablespoon of unscented chlorine bleach per gallon of water.

Cook Food to the Appropriate Temperature

Cooking food to the appropriate temperature is critical to killing harmful bacteria that can cause food poisoning. Always use a food thermometer to check the internal temperature of the food. The following are recommended cooking temperatures for some common foods:

Ground beef, pork, lamb, veal160°F (71°C)
Poultry (chicken, turkey, duck, goose)165°F (73.9°C)
Fish and shellfish145°F (62.8°C)
Eggs and egg dishes160°F (71°C)

Refrigerate Leftovers Promptly

Refrigerate leftovers promptly to prevent the growth of harmful bacteria. Store leftovers in shallow containers and refrigerate them within 2 hours of cooking. Make sure your refrigerator is set to 40°F (4°C) or lower and use perishable leftovers within 3-4 days.


Being aware of the symptoms of food poisoning, including fever, is crucial in preventing the spread of this illness. Symptoms such as diarrhea and vomiting are common, but if you experience a fever along with them, you should seek medical attention. Remember to stay hydrated and follow a bland diet while recovering, and take preventative measures such as proper food handling and cooking techniques to avoid getting sick in the first place. Stay healthy and safe!
