Food poisoning is a common condition that arises from consuming contaminated food. It is usually not life-threatening and often goes away on its own within a few days. However, in severe cases, food poisoning can lead to dehydration and organ damage, requiring immediate medical attention and hospitalisation. Treatment in hospitals for food poisoning focuses on rehydration and addressing the root cause of the poisoning. This may include administering IV fluids, blood and stool tests, and prescribing antibiotics or antiparasitic medications.

Rehydration: IV drips to replenish fluids and electrolytes lost from vomiting and diarrhoea
Food poisoning is usually not life-threatening, but it can cause severe dehydration due to vomiting and diarrhoea. Dehydration can be life-threatening and cause organ damage, so it is important to seek medical attention if symptoms are severe or prolonged.
Rehydration is the most important treatment for food poisoning. In most cases, drinking plenty of fluids and electrolytes is enough to treat dehydration. However, in rare cases, hospitalisation may be necessary to receive intravenous (IV) fluids if the patient is unable to keep fluids down due to persistent vomiting or severe diarrhoea.
IV rehydration therapy involves administering a sterile solution of water and electrolytes directly into the patient's bloodstream through a small tube inserted into a vein, usually in the arm. This method of fluid replacement is fast and effective, ensuring the body's fluid levels are restored quickly. IV fluids are typically combined with essential electrolytes, such as sodium and potassium, to replenish the body's salt balance, which is disrupted by frequent vomiting and diarrhoea.
In addition to IV fluids, hospitals may also administer medications to treat diarrhoea caused by food poisoning. For example, loperamide (Imodium) and bismuth subsalicylate (Pepto-Bismol, Kaopectate) can be used in adults, but these medications are not suitable for infants and children. In cases of bacterial food poisoning, such as Salmonella, antibiotics may also be prescribed.
It is important to note that most cases of food poisoning are mild and will resolve within a few days without medical intervention. However, if symptoms persist or worsen, it is always best to seek medical advice.

Antibiotics: Medication to treat bacterial food poisoning, e.g. Salmonella
Food poisoning is typically caused by consuming contaminated food or water. Most cases of food poisoning are not severe and do not require medical treatment, resolving within one to ten days. However, severe cases of food poisoning caused by bacteria such as Salmonella may require medical attention and treatment with antibiotics.
Salmonella is a common bacterial strain that can contaminate raw or undercooked chicken, turkey, meat, eggs, raw milk, juice, raw fruit, and vegetables. Symptoms of Salmonella food poisoning include diarrhea, nausea, stomach pain, and vomiting. In some instances, Salmonella poisoning can cause doubled and blurred vision, drooping eyelids, slurred speech, difficulty swallowing, and breathing difficulties.
If you suspect you have food poisoning, it is important to stay hydrated by replacing lost fluids and electrolytes. Over-the-counter medications may help relieve symptoms, but antibiotics are typically not recommended as they may prolong diarrhea and make food poisoning worse.
However, in cases of severe bacterial food poisoning, antibiotics may be prescribed. Antibiotics are medications that target and kill bacteria. In the context of food poisoning, they work by eliminating the bacteria responsible for the infection, such as Salmonella. Antibiotics can be effective in treating severe food poisoning caused by bacteria when administered promptly and appropriately.
It is important to note that not all cases of food poisoning are bacterial, and antibiotics are specific to bacterial infections. Other causes of food poisoning include viruses, parasites, and toxins. Therefore, proper diagnosis is crucial before initiating antibiotic treatment. Additionally, some cases of food poisoning may require hospitalization, especially if there are signs of life-threatening dehydration, organ damage, or other severe complications.

Probiotics: Live microbes to aid digestion and reduce diarrhoea
Probiotics are live bacteria that aid in the digestion of food or enzymes. They are similar to the microbes found in our digestive tract and can be found in natural foods such as onions, garlic, cabbages, sauerkraut, and yogurt.
Probiotics are sometimes recommended by doctors as a treatment for food poisoning, as studies suggest they may help shorten a bout of diarrhea. However, it is important to note that most people with a healthy immune system will recover from food poisoning without the need for probiotics. In addition, studies on the effectiveness of probiotics for treating food poisoning have been inconclusive, and most people will recover without them.
If you choose to take probiotics, it is generally safe to do so, although it is always recommended to consult with your doctor first, especially if you have a weakened immune system or are experiencing severe symptoms.
In addition to probiotics, there are several other treatments for food poisoning that focus on reducing diarrhea and preventing dehydration. These include replacing lost fluids and electrolytes, which is the most important treatment, and in some cases, over-the-counter or prescription medications may be recommended to relieve symptoms.

Preventative measures: Hospitals advise on food safety, preparation, and storage to prevent food poisoning
Food poisoning is a common condition that arises from consuming contaminated food or drinks. It is usually not life-threatening, but it can cause severe discomfort and, in some cases, lead to life-threatening dehydration and organ damage. The symptoms of food poisoning vary depending on the type of contaminant but often include nausea, stomach pain, vomiting, fever, and diarrhoea.
To prevent food poisoning, hospitals advise on food safety, preparation, and storage. Here are some preventative measures to reduce the risk of food poisoning:
Food Safety
- Be cautious of food that has been left out for too long, especially in warm temperatures. Bacteria can grow rapidly in such conditions, increasing the risk of food poisoning. Avoid consuming foods that have been sitting out for more than two hours or in temperatures above 90 degrees for over an hour.
- Stay informed about food recalls. Companies recall foods if they discover they could cause harm. If you own a recalled item, stop consuming it immediately and return it or dispose of it safely.
- When travelling to developing countries, be cautious about consuming local food and water to reduce the risk of traveller's diarrhoea.
Food Preparation
- Ensure that food is cooked thoroughly at high enough temperatures to kill harmful microbes.
- Wash fruits and vegetables before consumption to remove any potential contaminants.
- Avoid cross-contamination by using separate utensils and cutting boards for different types of food, especially raw meat and produce.
Food Storage
- Store perishable items properly and promptly to prevent bacterial growth.
- Keep your refrigerator at the appropriate temperature (below 40 degrees Fahrenheit) to slow the growth of most bacteria.
- Use airtight containers or sealed packaging to protect food from contaminants and moisture.
- Regularly clean and disinfect your refrigerator and kitchen surfaces to eliminate potential sources of contamination.
By following these preventative measures, you can significantly reduce the risk of food poisoning for yourself and others.

Diagnosis: Tests to determine the cause of food poisoning and best treatment
Food poisoning occurs when contaminated food or water is ingested. It is caused by bacteria, viruses, or toxins in the food we eat. Symptoms include vomiting, diarrhoea, nausea, and flu-like symptoms. In most cases, food poisoning does not require medical treatment, but severe cases may require hospitalisation.
Diagnosis:
To determine the cause of food poisoning and the best treatment, a doctor will first take an oral history. They will ask detailed questions about your symptoms and the specific foods you have eaten in the last few days. They will also inquire about your medical history, recent travel, contact with animals, and any antibiotic usage.
After taking your oral history, the doctor will perform a physical examination. They will check your blood pressure and pulse for signs of dehydration, which is a common complication of food poisoning. In some cases, a digital rectal exam may be performed to check for blood in the stool, as this can indicate the presence of an infection with bacteria or parasites.
Tests:
Blood and urine tests may be ordered to further evaluate dehydration, infection, and kidney function. Stool tests are also commonly used to identify the presence of viruses, bacteria, or parasites that may be causing food poisoning. In some cases, more invasive tests such as sigmoidoscopy, colonoscopy, or esophagogastroduodenoscopy (EGD) may be recommended if initial stool tests are inconclusive.
Treatment:
The treatment for food poisoning aims to address symptoms and prevent complications. Rehydration is a key aspect of treatment, as fluid loss due to vomiting and diarrhoea can lead to dehydration. In severe cases, an IV line may be inserted to administer fluids and medications. Antibiotics may be prescribed for certain types of bacterial food poisoning, but they are not typically necessary.
In addition to medical treatment, it is important to rest and allow your body to recover. Most cases of food poisoning resolve within a day or two without any specific treatment. However, if symptoms persist or worsen, further medical evaluation may be warranted.
