Food poisoning, typically caused by viruses, bacteria, or parasites, is spread through foods or drinks. Symptoms are often intense but do not last long, and in most cases, treatment is not needed. In some instances, though, food poisoning can have serious complications.
Some foods purchased from the grocery store may already be contaminated, with these foods posing the highest risk:
When safety protocols involving storage, cleaning, and preparation of these foods are not followed, food poisoning is a serious concern:
If you are experiencing these unpleasant symptoms, food poisoning may be to blame:
Symptoms may range from mild to severe, lasting just a few hours or up to several days. If symptoms persist, contact your Charleston GI specialist.
While uncommon, certain types of food poisoning, like botulism, may impact your nervous system. If you are experiencing these symptoms, seek medical attention immediately:
Most symptoms last a short time and subside without any medical treatment. But if symptoms like these persist, call your gastroenterologist as soon as possible:
Note for expectant mothers: See your doctor if you have a fever and other flu-like symptoms. Some mild infections can cause problems with pregnancy.
Your GI specialist will likely diagnose you based on symptoms, with no tests required. To rule out other conditions or to check for complications, your gastroenterologist may perform a physical exam, stool test, or blood test.
For most patients, the only treatment required involves replacing lost fluids. Over-the-counter medication may also be taken to ease symptoms. If food poisoning is caused by bacteria or parasites, your GI doctor may prescribe an antibiotic as well. Recent research has shown that probiotics, similar to the ones living in a healthy digestive tract, may also be helpful, especially for patients with diarrhea.
The proper storage, cooking, cleaning, and handling of foods can help prevent food poisoning. Here are some tips to keep in mind:

What types of microbes cause food poisoning?
Bacteria
Bacteria are microscopic organisms that enter the body through contaminated food or water, causing infection or disease. Salmonella and Escherichia coli (E. coli) are common types of bacteria that cause food poisoning. Because bacteria grow rapidly when food temperatures are between 40 and 140 degrees, keeping food properly refrigerated or cooking it properly can help prevent food poisoning.
Parasites
Parasites live inside other organisms and enter your body through food or water. Parasitic infections are rare in developed countries.
Travelers’ diarrhea
People visiting developing countries may develop travelers’ diarrhea.
Viruses
Viruses invade normal cells, causing infections that spread from one person to the next. Common viruses that cause food poisoning include norovirus and hepatitis A. Contaminated water can spread viruses to food, which may cause food poisoning upon consumption. Viruses can also spread when an infected person prepares food.
Which foods are more likely to contain harmful chemicals that cause food poisoning?
Harmful chemicals can also cause food poisoning and may be present in certain foods, like these:
How does food become contaminated?
Contamination can occur at any point from farm to table, with these poor practices putting people at risk:
Are there any other uncommon ways to get it?
Bacteria that can potentially cause food poisoning may be found in swimming pools, lakes, and other bodies of water. Plus, some bacteria, like E. coli, may be spread by exposure to infected animals.
Are food poisoning and foodborne illness the same thing?
Food poisoning is a type of foodborne illness, referring specifically to illnesses caused by a toxin in food. Foodborne illness is a broader term that incorporates all illnesses that result from any contaminated food.
