Salmonella infection , symptoms, treatment and prevention

Salmonellosis is a common bacterial disease that affects the intestinal tract. Salmonella bacteria usually live in the intestines of animals and humans and are eliminated in the intestines. People are often affected by water or contaminated food.

Salmonella infection - symptoms.

  • When you need to see a doctor.

What causes salmonella infection?

  • Infected food.
  • Unpasteurized dairy products.
  • Fruits and Vegetables
  • Improper handling of food on affected surfaces.
  • Pets and other infected animals.

Risk Factors.

  • International travel
  • Stomach or intestinal upset.
  • Immune problems.


  • Dehydration
  • bacteria
  • Reactive arthritis.

Prevention methods.

  • Wash your hands
  • Keep things separate.
  • Avoid eating fresh eggs.
  • Cook and store food properly.

Salmonella infection - symptoms.

Some people with salmonella infection have no symptoms. Most people develop diarrhea, fever and abdominal pain within 8 to 72 hours of exposure. Most healthy people recover within a few days to a week without any specific treatment.

In some cases, diarrhea can lead to severe dehydration and requires immediate medical attention. Fatal complications can occur even if the infection spreads beyond the intestines. The risk of salmonella infection is higher when traveling to countries where drinking water is clean and wastewater is not disposed of properly.

Salmonella infection is usually caused by eating raw or uncooked meat, poultry and eggs or egg products, or without pasteurized milk. The incubation period - the time between exposure to the disease - can range from 6 hours to 6 days. People with salmonella infection often think they have food poisoning.

Possible signs and symptoms of salmonella infection include.

  • Diarrhea
  • Abdominal pain (stomach),
  • Fever
  • Nausea
  • Vomiting
  • Colds

Signs and symptoms of salmonella infection usually last from a few days to a week. Diarrhea can last up to 10 days, but it can take months for the bowels to return to normal bowel movements.

Many types of salmonella bacteria cause typhoid fever, sometimes a deadly disease that is more common in developing countries.

When you need to see a doctor.

Most people do not need to seek medical help for salmonella infection, as it disappears on its own within a few days. However, if the infected person is an infant, young child, adult or a person with a weakened immune system.

Consult a physician if:

  • The symptoms last for more than a few days.
  • They are associated with high fever or bleeding stools.
  • The symptoms are dehydration, urinary symptoms like urination less-than-normal Urine color darker than normal.
  • Symptoms such as dry mouth and tongue
  • Salmonella bacteria live in the intestines of humans, animals and birds. Most people get salmonella by eating or drinking water.

What causes salmonella infection?

Affected foods

Include raw meat, chicken and seafood. Can reach nice meat and poultry during slaughter. Seafood can become contaminated if you cut it with contaminated water.

Raw or boiled eggs. Although the eggshell may seem like an excellent barrier against infection, some infected chickens produce eggs that contain salmonella before they form a shell.

Raw eggs are used in restaurants, like mayonnaise and Dutch sauce.

Unpasteurized dairy products.

Without pasteurized milk and dairy products - sometimes also called raw milk - can be contaminated with salmonella. The pasteurization process kills harmful bacteria, including salmonella.

Some freshly produced fruits and vegetables, especially imported varieties, can be watered in the field or washed with salmonella in contaminated water during processing. Contamination in the kitchen can also occur when raw meat and chicken juices come in contact with uncooked foods such as salads.

Foods that are not handled properly.

Many foods become contaminated when they are prepared by people who do not wash their hands properly after using the toilet or changing diapers or handling contaminated food.

Infected surfaces: Can also become infected when people touch a contaminated object and then put their fingers in their mouth.

Infected and other infected pets and pets, especially birds and reptiles, can carry salmonella bacteria on their wings, on their fur or on their skin, or in their mills. Some pet foods can be contaminated with salmonella and can infect animals.

Risk factors.

That may increase the risk of salmonella infection include:

  • Activities that may keep you in close contact with salmonella bacteria
  • Health issues that can usually weaken your resistance to infection.
  • International travel: Salmonella infections, including those that cause typhoid fever, are more common in developing countries with poor health.
  • Ownership, care or killing of animals. Some animals, especially birds and reptiles, may be carriers of salmonella. Salmonella can also be found in animal pens, ponds, cages and debris.
  • Stomach or intestinal diseases: There are many natural sources of protection against salmonella infection in the body.
  • For example, strong stomach acid can kill many types of salmonella bacteria. But some medical problems or medications can shorten these natural defenses.

Examples include:

  • Antacids. Salmonella bacteria can survive longer than a decrease in stomach acid.
  • Inflammatory bowel disease. This condition damages the intestinal mucosa, making it easier to install salmonella bacteria.
  • Last use of antibiotics. This can reduce the number of "good" bacteria in your gut, which can affect your ability to fight salmonella infections.
  • Immune problems: Some medical or medication problems increase the risk of getting salmonella by weakening your immune system.
  • It interferes with your body's ability to fight infections and diseases.

Examples include:

  • Harvester Cell Disease
  • Malaria
  • Anti-rejection drugs taken after organ transplantation
  • Corticosteroids


Salmonella infections are not usually fatal. However, in some people - especially infants and young children, adults, transplant recipients, pregnant women and people with weakened immune systems - complications can be dangerous.


If you cannot drink enough to replace the fluid lost due to diarrhea, you may be dehydrated. Warning symptoms include:

  • Urinating less than usual or dark urine
  • Dry mouth and tongue
  • Clogged eyes
  • Lack of tears When you cry
  • Being more tired than usual
  • Nervous fatigue or confusion


If salmonella infection penetrates the bloodstream (bacteria), it can affect tissues throughout the body, including:

  • Urinary tract (urinary tract infection)
  • brain and spinal cord (meningitis)
  • heart or valve (endocarditis)
  • bone or bone marrow (Osteomyelitis)
  • Vascular lining, especially if you have a vascular dysfunction, such as coronary artery bypass surgery

Reactive arthritis:

People with salmonella have a higher risk of developing reactive arthritis due to salmonella infection. Reactive arthritis, also known as Reiter's syndrome, is usually caused by:

  • eye irritation
  • urinary pain
  • joint pain.

Methods of prevention.

Contraceptives are especially important when preparing food or caring for children, the elderly and people with weakened immune systems.

Hand washing: Washing your hands thoroughly can help prevent the spread of salmonella in your mouth or any food you prepare. Rinse hands with soap and water for 20 seconds:

  • Use the bathroom.
  • Change diapers.
  • Treat raw meat or poultry.
  • Clean your pet's feces.
  • Touch pets or other animals and their habitats, especially reptiles or birds.

Keep things separate to prevent contamination:

  • Keep raw meat, poultry and seafood away from other foods in your refrigerator.
  • If possible, keep two choppers in the kitchen - one for raw meat and the other for fruits and vegetables.
  • Never place uncooked food on an unwashed dish that has previously contained raw meat.
  • Rinse well with water
  • Avoid eating raw eggs: In a homemade cake batter, ice cream, mayonnaise, Dutch sauce and egg liqueur containing raw eggs.
  • If you want to eat raw eggs, make sure they are pasteurized.
  • Cook and store food properly Make sure you cook food well and refrigerate or freeze it immediately.
