The most common cause of foodborne illnesses is contamination of food with bacteria, viruses, or toxins. Bacteria are the most common cause of foodborne illness, with viruses and toxins coming in a close second. The best way to prevent foodborne illness is to practice food safety, including washing hands and food surfaces, cooking food properly, and avoiding cross contamination.

1. What is foodborne illness?
Foodborne illness is any illness that is caused by eating contaminated food. Contamination can occur at any point during food production and handling, including minutes before you eat it.
2. Symptoms of foodborne illness
The symptoms of foodborne illness range from very mild to severe. They can occur anywhere from a few hours to a few days after eating the contaminated food. Symptoms include:
– cramps
– diarrhea
– fever
– headache
– nausea and vomiting.
In severe cases, symptoms can include:
– blood in vomit or stools
– dehydration, which can lead to shock
– severe abdominal pain and cramping
– paralysis
3. Who gets foodborne illness? Everyone is at risk for getting foodborne illness, but some groups are more likely than others to get seriously ill when they do get sick from contaminated food. These groups include:
– infants and young children
– pregnant women
– older adults
– people with weakened immune systems, such as people with cancer or HIV/AIDS, transplant recipients, or people taking certain medications
2. What are the most common causes of foodborne illness?
The most common symptoms of foodborne illnesses are abdominal cramps, diarrhea, fever, headache, and vomiting. The incubation period is the time between consuming contaminated food and when symptoms first appear.
There are many different agents that can cause foodborne illness, including bacteria, viruses, and parasites. These agents can contaminate food at any point during its production, processing, or preparation. The most common causes of foodborne illness are described below.
Bacteria
Bacteria are single-celled organisms that can be found everywhere in the environment, including on our skin and in the air we breathe. Most bacteria are not harmful to humans and some are even essential for our health, such as those that live in our intestines and help us digest food. However, some types of bacteria can cause disease.
The main ways bacteria can contaminate food are through contact with animal feces or contaminated water during production or processing. Poor hygiene during food handling can also lead to bacterial contamination.
Common examples of bacteria that cause foodborne illness include Campylobacter, Listeria monocytogenes, Salmonella enterica serovar Typhi (Typhoid fever), Shigella spp., Staphylococcus aureus (Staph), Streptococcus pyogenes (Strep), and Yersinia enterocolitica.
Viruses
Viruses are tiny infectious particles that can only replicate inside the cells of a living host. They cause a wide range of human illnesses, from the common cold to more serious diseases such as HIV/AIDS and Ebola virus disease.
Most viruses that cause human disease cannot infect animals or plants. However, there are some viruses—such as the Norovirus—that can infect both animals and humans (these are known as “zoonotic” viruses). Zoonotic viruses can be transmitted to humans through contaminated animal products or contact with infected animals.
Common examples of zoonotic viruses that cause foodborne illness include Hepatitis A virus (HAV), Hepatitis E virus (HEV), Norovirus (Norwalk-like virus), Rotavirus A (RVA), and Sapovirus (SaV).
Parasites Intestinal parasites are organisms that live in the digestive tract of humans or animals and depend on their host for survival. They can be transmitted to humans through contaminated water or food, contact with infected animals, or direct contact with an individual who is already infected. Some parasites—such as Giardia lamblia—can also be spread through contact with contaminated surfaces such as doorknobs or changing tables in public restrooms
3. How can you prevent foodborne illness?
The most common cause of foodborne illness is Norovirus. This virus is spread through contaminated food, water, or surfaces. It can also be spread through contact with an infected person, such as touching their food or sharing utensils. The best way to prevent Norovirus is to practice good hygiene, including washing your hands thoroughly with soap and water and avoiding contact with others who are sick. You can also help prevent Norovirus by preparing food properly and cooking it to the proper temperature.
4. What are the symptoms of foodborne illness?
The symptoms of foodborne illness can vary depending on the bacteria or virus causing the infection. They can range from mild to severe, and some can even be life-threatening. The most common symptoms include:
-Nausea
-Vomiting
-Diarrhea
-Abdominal cramps
-Fever
-Body aches
-Chills
5. When should you seek medical attention for foodborne illness?
You should seek medical attention if you have any of the following symptoms:
-High fever (above 101.5°F)
-Prolonged vomiting that prevents keeping liquids down
-Diarrhea that lasts more than 3 days
-Signs of dehydration, such as decreased urination, dry mouth and throat, and feeling dizzy when standing up
-Blood in the stool
-Jaundice (yellowing of the skin and eyes)
6. What are the treatments for foodborne illness?
There are a variety of treatments for foodborne illness, depending on the cause. Some foodborne illnesses, such as botulism, require hospitalization and immediate medical attention. Other illnesses, such as salmonellosis, can be treated at home with rest and fluids.
If you think you have a foodborne illness, it is important to see a doctor or other healthcare provider right away. You may need to be hospitalized if you have a severe case of food poisoning. You may also need to be treated with antibiotics.
7. What is the prognosis for foodborne illness?
The natural history of foodborne illness depends on the specific pathogen causing the infection, as well as the age and overall health of the affected individual. The incubation period is the time from ingestion of the pathogen until illness onset. This period ranges from hours to days, or in some cases, weeks. The incubation period for bacterial foodborne illnesses is generally shorter than that for viral infections.
Most foodborne illnesses are acute and self-limited, meaning that they resolve within days to weeks without intervention. However, some infections can lead to severe complications, including dehydration, life-threatening electrolyte imbalances, and even death. Infections caused by certain bacteria, such as Listeria monocytogenes and Escherichia coli O157:H7 can cause sepsis, a potentially life-threatening condition caused by infection-related inflammation throughout the body. Other bacterial pathogens, such as Shigella species and Campylobacter species can cause bloody diarrhea and occasionally lead to long-term consequences such as irritable bowel syndrome.
8. What are the long-term effects of foodborne illness?
Long-term effects of foodborne illness can include chronic arthritis, brain and nerve damage, and cancer. Some foodborne illnesses can lead to death.
9. What are the complications of foodborne illness?
Foodborne illness can cause a range of serious complications, including:
-Dehydration
-Damage to your kidneys or liver
-Brain damage
-Coma
-Death
Can foodborne illness be prevented?
Most cases of foodborne illness can be prevented by following proper food handling and food safety guidelines. These guidelines include cooking foods to proper temperature, storing food at safe temperatures, not leaving food out at room temperature for more than two hours, practicing good personal hygiene, and washing hands and surfaces often. In addition, it is important to only consume food from reputable sources, such as restaurants that follow proper food safety guidelines.
