Top Foodborne Illness Outbreaks and How To Prevent Them
The Top Most Recent Foodborne Illness Outbreaks in the US
Before we look at the latest foodborne illness outbreaks let's do a brief backgrounder to give us a clearer understanding of the incidents.
Causes of Foodborne Illness Outbreaks
Foodborne illnesses are caused by bacteria, viruses, parasites, and toxins. Here are some of the more familiar culprits.
- Salmonella - Salmonella lives in the intestines. Symptoms include abdominal cramps, fever, and, most dangerously, diarrhea. Fortunately, when treated, most people recover within 4 to 7 days.
- Cyclospora - Cyclospora is a parasite that infects the bowels. A cyclospora infection is due to eating contaminated raw fruits and vegetables. Symptoms include diarrhea, stomach cramps, and tiredness. Untreated cyclospora may last for a few days to a month.
- Listeria - Listeria is a bacteria that causes a disease with symptoms that include fever, headache, tiredness, and general aches and pains. Treatment is through antibiotics
- E. Coli - A name for a group of bacteria that reside in the intestines. E. Colie causes urinary tract infections, respiratory illness, and diarrhea.

Now that we've looked at the causes of foodborne illnesses and actual outbreaks that have happened let's look at prevention.
How To Prevent a Foodborne Illness Outbreak
The U.S Food and Drug Administration (FDA) monitors the situation on the national level. The FDA is reactive to outbreaks in order to control infection and prevent further damage. It is proactive in evaluating how future outbreaks can be prevented.
The FDA has a group called the CORE Network. According to the CORE Network site-
With CORE, FDA brought together expertise in medicine, public health, and science to coordinate its efforts to find, stop, and prevent foodborne illness outbreaks. In CORE, full-time teams work on various aspects of investigations from beginning to end. They hit the ground running on new outbreaks, which speeds the response, ensures continuity, and standardizes processes.
Ways to Prevent Foodborne Illness
Whether you are a restaurant, a catering service, or an individual here are the ways to prevent foodborne illness outbreaks.
- Make sure food is completely cooked. Bacteria like Salmonella cannot survive cooking. This is true as well for toxin-causing algae in shellfish. When in doubt of hygienic preparation keep away from raw or lightly cooked food.
- Don't wash meat by dunking it in water. Dunking the meat in water can spread germs from parts of the meat to other parts, maybe even to other foods or kitchen surfaces, increasing the chance for infection. Wash meat under flowing water
- Be conscious of food contact. A contaminated piece of meat and vegetable can infect other foods by simple contact. They can also transfer germs to other food if you use the same utensil for infected food with other food.
- Make it a habit to wash knives and other utensils when using them on different foods. Always wipe down kitchen surfaces to keep them clean from infections.
- Wash fruits and vegetables. Even if you are going to eat fruits and vegetables raw washing the rind or skin will remove any contaminants.
- Store fish at the proper temperature. Failing to refrigerate fish for prolonged periods will encourage the spread of histamine produced by bacteria.
- Consume pasteurized foods. Pasteurization is a method of heating food that kills germs. It is advisable to patronize pasteurized foods - this is usually applicable to dairy products like milk and cheese.
- Do not eat damaged eggs or eggs with dirty shells. Eggs are a source of Salmonella which can be particularly risky when eating undercooked or raw eggs.
