- Pregnant women
- Immunocompromised people
Let’s dig deeper about this illness and understand every single factor about it. In this article, we will learn the causes, symptoms, treatment, types, home remedies, tests, and prevention of food poisoning.
What are The Symptoms of Food Poisoning (Foodborne Illness)?
The signs and symptoms of food poisoning may vary depending on several factors. Sometimes the symptoms are very mild and sometimes the disease shows severe symptoms.
Usually, the person affected by swallowing the contaminated food starts to show the signs within a few hours. In some cases, it may take weeks for the symptoms of food poisoning to appear. Let’s understand the signs of food poisoning in varied situations.
1) Most common symptoms of food poisoning that usually occur are:
- Mild fever
- Loss of appetite
- Abdominal cramps
- Muscle aches, etc.
2) Some symptoms of food poisoning that may be life-threatening are:
- Bloody urine
- Severe dehydration symptoms, such as dry mouth, passing little to no urine
- Visual or vocal difficulties
- High fever (>102 degrees F or 38.9 degrees C),
- Diarrhea for more than 3 days
3) The symptoms of some less common food poisoning are:
- Numbness or tingling in arms
- Blurred vision, etc.
The symptoms may vary from person to person depending on the severity. If you find yourself even a little doubtful about anything related to the symptoms, consult your healthcare provider as soon as you can.
What are The Causes of Food Poisoning (Foodborne Illness)?
Mainly food poisoning is caused by consuming contaminated food or drinks. Three types of pathogens that may get attached to the food items to cause food poisoning are bacteria, viruses, and parasites.
Food contamination is possible at any particular step of its overall stages of production. The stages of food preparation include growing, harvesting, processing, storing, shipping, or preparing. But the humans get affected by this contaminated food only after they swallow it.
The pathogens that are responsible for causing food poisoning can be detected in the food items consumed by humans. But the process of cooking is likely to kill these pathogens. Therefore, uncooked or raw food items are usually known to make humans infected with a foodborne disease called food poisoning.
The food items which commonly carry these germs are:
- Food items that are not properly sealed.
- Fresh produce
- Processed and ready-to-eat meat such as deli meat or hot dogs.
- Raw or uncooked meat, eggs, and poultry.
- Baked goods, sandwiches, cut fruit, salads, sliced meat, etc.
- Fruit juices and dairy products that are kept without pasteurization (a method used to kill harmful microbes).
- Fish and shellfish.
Responsible Pathogens or Types of Food Poisoning
Let’s understand with the help of a table, pathogens that may be responsible for food poisoning and the different factors related to it (1).
Tests For Food Poisoning
Usually, food poisoning with mild symptoms goes up on its own. But if you find some critical symptoms which you find difficult to get cured on your own, it is the time you should seek medical attention.
Consult your health care provider when you see the following symptoms of food poisoning:
- Frequent vomiting
- Inability to keep liquids
- Blood in stools or vomit
- Diarrhea that resists more than 3 days
- Severe pain in the abdomen or cramps
- More than 100.4°F body temperature.
- Certain neurological symptoms include tingling in the arms, muscle weakness, and blurry vision.
- Signs of dehydration include lightheadedness, dizziness, severe weakness, difficulty in passing urine, dry mouth, excessive thirst, etc.
After the appearance of these are the symptoms, you should immediately check with your doctor.
Your health care provider will do the following tests to check the severity of complications:
|Tests||What It Helps to Determine|
|Imaging test (MRI and CT Scan)||It is not particularly used to determine food poisoning. But often used to rule out other probable causes of symptoms.|
|Stool or blood test||It helps to determine deadly toxins such as botulism.|
|Blood Test||This test helps to detect Listeria monocytogenes and the hepatitis A virus.|
|Stool cultures||This test helps to determine if the infection is related to bacteria, which bacteria is responsible for it, and which antibiotics will kill it.|
What is The Treatment of Food Poisoning?
Usually, food poisoning does not require any critical treatment. It gets resolved on its own at home. The treatment completely depends on the type of pathogen you get affected with. Some illnesses of food poisoning resolve in just a few days, whereas, some take a little longer time.
Here are some ways to treat food poisoning. Let’s understand them.
Focus on Hydration
It’s very important in food poisoning that you should focus on keeping your body hydrated. Increase the intake of fluids such as regular water, coconut water, fruit juices, etc. Also, you can consume drinks that are rich in electrolytes. Avoid caffeine-rich products.
Take Proper Rest
Giving proper rest to your body is also important during such conditions. It helps to relieve your illness soon.
Over-The-Counter (OTC) Medications May Help
Diarrhea, nausea, etc. are very common during food poisoning. OTC medications such as loperamide and Pepto-Bismol can help you manage diarrhea and suppress nausea.
You should ask your healthcare provider for these over-the-counter medications to treat the symptoms that come with this food-borne illness; because your body uses diarrhea and vomiting to rid the system of the toxin.
Using these OTC medications may also mask the severity of the disease and cause you to delay seeking expert treatment.
To treat the food poisoning caused by some specific pathogens, you may need some prescription medicine. Your doctor will check or do some tests to detect the pathogen and prescribe medicines accordingly. Prescription medicines are helpful for people who are at higher risk of food poisoning such as pregnant women, immunocompromised persons, older people, etc.
Receiving Antitoxin Is Required For Certain Conditions
Some infections of food poisoning are considered emergencies and require medical treatment. Doctors administer suitable antitoxin depending on the medical condition and particular age range.
Food poisoning with C. botulinum is considered a medical emergency and you should seek medical care as soon as you can. Your doctor will administer an antitoxin. Babies with this infection will receive a special antitoxin called BabyBIG (botulism immune globulin).
Requires IV (Intravenous) Fluid
If your particular case of food poisoning is becoming critical, there is a requirement to get hospitalized. The healthcare provider will administer IV fluid to hydrate your body. The time duration of hospitalization depends on the severity.
People with severe cases of C. botulinum food poisoning may even require mechanical ventilation.
Prevention of Food Poisoning (or Foodborne Illness)
Standard advice to avoid food poisoning includes the following four key components (2):
|Cook||Cooking the food at the right temperature kills the harmful bacteria present in them. One can use a cooking thermometer to check the adequate temperature to cook any particular food.|
|Separate||To prevent cross-contamination of bacteria, keep the food items separately. Especially ready-to-eat foods should be kept separate from raw food items.|
|Clean||Properly clean utensils, worktops, cutting boards, and other items used to cook. Also, wash hands frequently with soap or hand-wash, mainly after handling raw meat or eggs and before eating or touching your mouth.|
|Refrigerate (Chill)||Keeping the food in chilled places such as the refrigerator slows down the growth of harmful bacteria in them.|
Diagnosis of Food Poisoning
Your doctor may be able to diagnose the type of food poisoning according to your symptoms.
In severe cases, your doctor may recommend stool tests, blood tests, and tests on food that you have consumed, to determine the cause of the food poisoning. The doctor may also use a urine test to determine whether you are suffering from dehydration due to food poisoning.
