What are the causes of salmonellosis?
Consuming contaminated food and water is one of the most common reasons for this infection in humans. Moreover, if you are a frequent traveler and often eat your meals outside, you are at a higher risk of getting this infection. The reason is the lack of hygiene and poor sanitation practices in various parts of the world.
The following are the possible cause of salmonella infection:
- Food you eat
As it is a foodborne condition, the foods that commonly lead to food poisoning include the following –
- Raw and undercooked meat, seafood, and poultry – During meat and poultry processing, excreta (feces) may stick to the raw meat. Similarly, seafood can get contaminated by disease-causing microorganisms if collected from a polluted water body.
- Uncooked eggs – Although the outer covering (shell) of eggs gives sufficient protection from external contamination, infected birds can produce eggs with salmonella before shell formation.
- Vegetables and fruits – Fresh fruits and vegetables, especially the ready-to-cook, imported, or packaged produce, might contain salmonella due to contamination during processing. Using the same chopping board for cutting meat and vegetables can lead to contamination of the raw produce, especially salads.
- Improper hand hygiene
If you do not practice proper hand hygiene, for example – not washing hands after going to the washroom, changing sanitary napkins or diapers, or playing with or touching your pets, you can end up contaminating your food.
What are the risk factors associated with salmonellosis?
Following are the risk factors for this infection –
- Children, especially those below five years, are at an increased risk of contracting salmonella infection.
- Traveling to places with poor sanitation increases the risk of getting salmonella infection.
- The use of antacid lowers your stomach acidity allowing the Salmonella bacteria to thrive in your system.
- Frequent use of antibiotics may impair the ability of your body to fight off the infection.
- If you are suffering from an autoimmune disorder, such as AIDS and sickle cell disease, you are at a higher risk.
What are the possible complications of salmonellosis?
Food poisoning due to salmonella infection is not a life-threatening condition. However, in people with any comorbidity or suppressed immunity, pregnant women, elderly, infants, and young kids, and transplant patients, among others, any health complications can be fatal. The complications include:
1. Severe dehydration
If you have diarrhea and your fluid intake is low, you can get dehydrated. It can further deteriorate your condition, followed by dry mouth, decreased urine output, and sunken eyes.
2. Bacteremia
If salmonella infection gets into your bloodstream, it can lead to severe tissue damage throughout your body. It includes the following –
- Meningitis (inflammation of the tissues around your spinal cord and brain)
- Osteomyelitis (inflammation of the bone due to infection)
- Endocarditis (an infection in the inner lining of your heart)
3. Reactive arthritis
If you have had salmonellosis, you are more likely to be at a higher risk of acquiring reactive arthritis or Reiter’s syndrome. The signs and symptoms of reactive arthritis include –
- Irritation of the eye
- Pain the joints
- Painful urination
How can simple hygiene help prevent salmonellosis?
You can minimize the risks of contracting salmonella infection by following some simple hygiene tips. It includes –
Keep your hands clean
- Your hands can play the role of a germ-carrier to your mouth or the food you are handling .
- It is essential to wash your hand with soap and water after using the toilet, changing period products, changing a diaper, cleaning pet feces, playing with pets, cleaning the washroom, and handling raw foods.
Keep your food preparation slab and products clean.

- Wash everything, starting from your hands, kitchen countertops, chopping boards, utensils, and knives, and choppers after processing raw meat. It will help you prevent cross-contamination.
- Do not forget to wash fresh produce like fruits and vegetables properly before eating or cooking.
- Refrain from using unpasteurized dairy products.
Prepare and store your food at the right temperatures.
- Avoid eating undercooked or raw eggs. When preparing recipes that do not need cooking like mayonnaise, hollandaise sauce, flan, or ice cream, make sure to use pasteurized eggs.
- Cooking your food at appropriate heat kills bacteria and many other microbes. So, whenever cooking meat, make sure that there is no pink (raw) portion in the middle of it.
Be careful when swimming.
Make sure not to swallow pool or pond water while swimming.
