What is Samonellosis?
are bacteria which cause an infection called salmonellosis
in the stomach and intestines. About 2,000 types of Salmonella
have been identified. However, only a small number of those
types account for cases in Utah. Typhoid fever is the most
serious type of Salmonella infection.
can get salmonellosis, but it occurs more often in infants
and young children.
are Salmonella bacteria spread?
bacteria are spread by eating or drinking infected food
or water. It can also be spread by direct contact with an
infected person or animal. Person-to-person spread often
occurs in day-care centers and nursing homes where personal
hygiene may be poor due to age or disabilities.
are the symptoms of Salmonellosis?
infected with Salmonella commonly have headache,
stomach pain, diarrhea, nausea, vomiting and almost always
fever. Infections may enter the blood stream and be very
serious in the very young or very old. Not all people infected
with Salmonella will become sick. However, these
people may excrete the bacteria and become a source of infection
soon after infection do symptoms appear?
usually appear within 6-72 hours after infection.
are Salmonella bacteria found?
bacteria are commonly found in food products such as eggs,
egg products, meats, meat products, poultry, unpasteurized
milk, other unpasteurized dairy products, fruits, vegetables,
and cheese. Most domestic animals including chickens, cattle,
pigs, ducks, dogs, and cats have been found to carry the
bacteria. Recently, Utah as well as the rest of the U.S.
has seen an increase in Salmonella infection
as the result of increased ownerships of exotic animal species
such as reptiles.
long can an infected person carry Salmonella?
period of time a person may spread the infection can be
several days to months. People who are given antibiotics
may carry the bacteria for a longer time than others.
infectious people need to be excluded from work or school?
with diarrhea (especially children in day-care and people
who handle food) should not go to day-care, school or work.
Most infected people may return when diarrhea stops if they
carefully wash their hands after using the toilet. Food
handlers should not handle food until they have submitted
two negative stool cultures.
is the treatment for Salmonellosis?
people recover on their own. However, small children, the
elderly, and others with severe diarrhea should see a doctor.
is Salmonellosis diagnosed?
is diagnosed by laboratory examination of a stool sample.
The laboratory work usually takes several days to complete
and will indicate the type of Salmonella bacteria
can Salmonellosis be prevented?
