What are causes of E. coli vs. salmonella?

There are several causes of E. coli and salmonella. E. coli can be a healthy or harmful bacteria, depending on the type that you encounter. Salmonella is a harmful group of bacteria that can be found in certain foods and on certain pets.

Causes of E. coli

E. coli can be found in water, food, soil, or on surfaces that have been contaminated with animal or human feces. People can spread E. coli, even if they don’t have symptoms. You can become infected with E. coli by the following:

Eating contaminated food like undercooked hamburgers or raw produce
Drinking unpasteurized milk, juice, or cider
Swallowing contaminated water in a lake, stream, river, spring, pond, swimming pool, hot tub, or water park fountains
Contact with farm animals or pets
Touching contaminated surfaces or objects, then touching your mouth
Not washing your hands after using the bathroom then eating

Causes of salmonella

Salmonella lives in the intestines of animals, like birds. It is usually transmitted by eating foods contaminated with animal feces. Typhoid fever is caused by a certain type of salmonella that only lives in humans and is passed through contaminated water or food. You will typically be infected by salmonella from contaminated:

Beef
Poultry
Seafood

How to diagnose E. coli vs. salmonella

Most often, E. coli and salmonella cases will go unreported because they typically resolve within a week. If you do visit the doctor for food poisoning, they will test a sample of your stool to accurately diagnose the bacteria in your body. Proper diagnosis can prevent secondary transmission that lead to outbreaks.

If you have concerning severe symptoms like those listed above you should contact your doctor immediately. They will be able to run tests and determine what strain of bacteria is present in your stool. This will help local public health departments take the necessary protocol for managing a potential outbreak.

Salmonella and E. coli have very similar symptoms, so your doctor will send your stool off to the lab to determine if salmonella or E. coli is present in your system.

Treatments of E. coli vs. salmonella

In most cases, you will be able to recover from E. coli or salmonella within four to seven days without treatment. Your doctor will determine the best path of treatment for you depending on the severity of your infection, your age, and your overall health. If you have severe diarrhea, you may need rehydration through IV fluids.

Getting plenty of fluids is an important part of your treatment plan. Antibiotics are not recommended to treat E. coli or salmonella infections. Unless your infection has spread to your bloodstream, which is a serious condition and would require immediate treatment of antibiotics.
