Salmonella food poisoning

Salmonella food poisoning: Introduction

Salmonella food poisoning is the most common reported cause of food borne illness or food poisoning. Salmonella food poisoning, medically known as salmonellosis, is a type of bacterial infection caused by a variety of types of Salmonella bacteria.

Salmonella food poisoning is spread from the feces of people or animals through food or beverages that have been contaminated with feces that contain salmonella bacteria. Common sources of foods contaminated with Salmonella bacteria include undercooked eggs and chicken and poultry. However, many types of foods and beverages can also be contaminated with Salmonella bacteria and cause salmonella food poisoning. These include any raw food that comes from animals, such as seafood, meat, milk and dairy products. Some fruits and vegetables may also be contaminated with Salmonella bacteria and cause Salmonella food poisoning.

Any food can become contaminated with Salmonella bacteria and cause salmonella food poisoning if it is handled by an infected person with unwashed hands or if it comes in contact with contaminated food.

Salmonella bacteria that cause Salmonella food poisoning can also be found in the feces of pets with diarrhea. It is often found in the feces of reptiles, even if they are healthy.

Salmonella food poisoning results in a bacterial infection and irritation and inflammation of the gastrointestinal tract. This leads to symptoms that include abdominal pain, nausea, fever, headache, and diarrhea. Salmonella food poisoning can result serious complications that include dehydration, Reiter's syndrome, and arthritis. For more details about symptoms and complications, see symptoms of Salmonella food poisoning.

Salmonella food poisoning can occur in any age group or population. People most at risk for serious complications due to Salmonella food poisoning include older adults, pregnant women, infants, children, and people who have compromised immune systems. This group includes people with diseases that affect the normal functioning of the immune system, such as HIV/AIDS, diabetes, cancer, and kidney disease. People at risk also include those who take medications that affect the immune system, such as chemotherapy.

Diagnosing Salmonella food poisoning and its root cause begins with taking a thorough personal and family medical history, including symptoms, and completing a physical examination.

A stool sample is generally taken and tested in the laboratory to determine if Salmonella bacteria are present. This is called a stool culture and sensitivity. A blood test may also be done to check if the Salmonella bacteria have spread to the blood.

Diagnosis may also include a complete blood count, which can help to determine if an infectious process, such as Salmonella food poisoning, is present. A chemistry panel is a blood test that can evaluate if Salmonella food poisoning has lead to the complication of dehydration. An urinanalysis can also help to determine dehydration.

A diagnosis of Salmonella food poisoning can be delayed or missed for a variety of reasons. For information on misdiagnosis, refer to misdiagnosis of Salmonella food poisoning.

Salmonella food poisoning can often be prevented by taking simple hygiene and food preparation precautions. Treatment of Salmonella food poisoning involves ensuring good hydration until symptoms pass, generally within three to seven days for healthy adults. Medications include antibiotics. For more information on prevention and treatment, refer to treatment of Salmonella food poisoning. ...more »

Prognosis for Salmonella food poisoning: most persons recover without treatment. (Source: excerpt from Salmonellosis (General): DBMD) ... While most people recover successfully from salmonellosis, a few will experience long-term symptoms such as arthritis. Salmonellosis can be a very serious or even deadly infection in those who are very young, elderly, or have weakened immune systems. (Source: excerpt from Foodborne Diseases, NIAID Fact Sheet: NIAID)

Article Excerpts about Salmonella food poisoning

FDA Bad Bug Book (Excerpt)

Name of the Organism:: Salmonella spp. Salmonella is a rod-shaped, motile bacterium -- nonmotile exceptions S. gallinarum and S. pullorum--, nonsporeforming and Gram-negative. There is a widespread occurrence in animals, especially in poultry and swine. Environmental sources of the organism include water, soil, insects, factory surfaces, kitchen surfaces, animal feces, raw meats, raw poultry, and raw seafoods, to name only a few. (Source: FDA Bad Bug Book)

Salmonellosis (General): DBMD (Excerpt)

Salmonellosis is an infection with a bacteria called Salmonella. Most persons infected with Salmonella develop diarrhea, fever, and abdominal cramps 12 to 72 hours after infection. The illness usually lasts 4 to 7 days, and most persons recover without treatment. However, in some persons the diarrhea may be so severe that the patient needs to be hospitalized. In these patients, the Salmonella infection may spread from the intestines to the blood stream, and then to other body sites and can cause death unless the person is treated promptly with antibiotics. The elderly, infants, and those with impaired immune systems are more likely to have a severe illness. (Source: excerpt from Salmonellosis (General): DBMD)

Definitions of Salmonella food poisoning:

A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that utilizes citrate as a sole carbon source. It is pathogenic for humans, causing enteric fevers, gastroenteritis, and bacteremia. Food poisoning is the most common clinical manifestation. Organisms within this genus are separated on the basis of antigenic characteristics, sugar fermentation patterns, and bacteriophage susceptibility. - (Source - Diseases Database)

A kind of food poisoning caused by eating foods contaminated with Salmonella typhimurium - (Source - WordNet 2.1)

Ophanet, a consortium of European partners, currently defines a condition rare when it affects 1 person per 2,000. They list Salmonella food poisoning as a "rare disease".
