Which Contaminant Poses the Greatest Foodborne Illness Risk?
Foodborne illness, also known as food poisoning, is a common illness caused by the consumption of contaminated food. It can be caused by a variety of contaminants, including bacteria, viruses, parasites, and toxins.
Which contaminant poses the greatest foodborne illness risk?
The answer to this question depends on a number of factors, including the type of contaminant, the food it is found in, and the way the food is prepared.
Bacteria are the most common cause of foodborne illness. They are single-celled organisms that can grow quickly at favorable temperatures. Some bacteria are harmless, but others can cause serious illness, even death.
The Centers for Disease Control and Prevention (CDC) estimates that norovirus and Salmonella are the top two pathogens that cause hospitalizations from foodborne illness. Salmonella is the top estimated pathogen to cause foodborne illness deaths.
Norovirus is a highly contagious virus that can cause vomiting, diarrhea, and stomach cramps. It is often spread through contact with contaminated food or surfaces.
Salmonella is a bacterium that can be found in a variety of foods, including poultry, eggs, meat, and dairy products. It can cause symptoms such as diarrhea, fever, and abdominal cramps.
Other bacteria that can cause foodborne illness include:
- Campylobacter
- E. coli
- Listeria
- Staphylococcus aureus
- Vibrio
Viruses can also cause foodborne illness. The most common foodborne viruses include:
- Hepatitis A
- Hepatitis E
- Norovirus
- Rotavirus
- Astrovirus
Parasites can also be found in food. The most common foodborne parasites include:
- Giardia
- Cryptosporidium
- Toxoplasma
- Trichinella
Toxins can also contaminate food. The most common foodborne toxins include:
- Botulinum toxin
- Staphylococcal enterotoxin
- Solanine
- Aflatoxin
How to reduce your risk of foodborne illness
There are a number of things you can do to reduce your risk of foodborne illness:
- Wash your hands thoroughly with soap and water for at least 20 seconds before, during, and after handling food.
- Cook food to the proper internal temperature.
- Refrigerate food promptly.
- Do not cross-contaminate food.
- Avoid eating raw or undercooked meat, poultry, and eggs.
- Wash fruits and vegetables thoroughly before eating.
By following these simple steps, you can help protect yourself and your family from foodborne illness.

- How is foodborne illness treated?
Answers to additional questions
- The symptoms of foodborne illness can vary depending on the type of contaminant that caused the illness. Common symptoms include diarrhea, vomiting, nausea, stomach cramps, fever, and headache.
- The time it takes for symptoms of foodborne illness to appear can also vary depending on the type of contaminant. In general, symptoms of foodborne illness caused by bacteria appear within 24 to 48 hours after eating contaminated food. Symptoms of foodborne illness caused by viruses can appear within hours of eating contaminated food, or they may not appear for several days.
- Foodborne illness is often diagnosed based on the patient’s symptoms and a history of exposure to contaminated food. In some cases, laboratory tests may be used to confirm the diagnosis.
- Foodborne illness is often treated with supportive care, such as rest, fluids, and over-the-counter medications to relieve symptoms. In some cases, hospitalization may be necessary.
By understanding the risks of foodborne illness and taking steps to reduce your risk, you can help protect yourself and your family from this serious health problem.
