But what causes these illnesses and how can they be prevented? Prepare to find out as we dive deep and explore What Causes Foodborne Illness in this informative article.


Every year, approximately 1 in 6 Americans contract a foodborne illness. These illnesses can range from minor stomach aches to severe cases that require hospitalization. The most common symptoms include nausea, vomiting, diarrhea, and fever. In severe cases, they can even lead to death. But what is it that causes foodborne illnesses, and how can we prevent them? In this article, we will explore these questions and discuss everything you need to know about What Causes Foodborne Illness.

1. Bacteria:

🦠 Bacteria are one of the most common causes of foodborne illness. Some of the most well-known bacteria include Salmonella, E. coli, and Listeria. These bacteria can be found in a variety of foods, including raw meat, eggs, and dairy products. When these foods are not cooked or stored properly, the bacteria can grow and multiply, leading to illness.

2. Viruses:

🦠 Just like bacteria, viruses can also cause foodborne illnesses. The most common virus that causes food poisoning is norovirus. This virus can be found in contaminated food or water and can spread quickly, especially in group settings like cruise ships or schools.

3. Parasites:

🦠 Parasites are another type of microorganism that can cause foodborne illness. Examples of parasites that can contaminate food include tapeworms and toxoplasma. These parasites can be found in undercooked or raw meat, which is why it’s important to cook meat to the proper temperature.

4. Chemical contamination:

🦠 While less common than bacterial or viral contamination, chemicals can also make their way into food and cause illness. Chemicals like pesticides and cleaning products can contaminate food if they come into contact with it during the growing or processing stages.

5. Allergens:

🦠 For people with certain food allergies, even a tiny amount of the allergen can cause a severe reaction. Cross-contamination, where allergens from one food come into contact with another food, can also be a risk. Some common allergens include peanuts, tree nuts, shellfish, and dairy products.

6. Toxins:

🦠 Some foods can naturally contain toxins that are harmful to humans. For example, certain types of mushrooms are poisonous and can cause illness or even death if consumed. Another well-known toxin is histamine, which can be found in improperly stored tuna and can cause an allergic-like reaction.
