Salmonellosis: symptoms

Salmonellysis: symptoms and how to take it. Advice to avoid "contagion", care and risks in case of pregnancy and salmonellosis in children.

We have told you that the most common zoonoses are those transmitted by pets such as dogs and cats (dog zoonoses and cat zoonoses), however there are some diseases that see vectors less welcomed in the home but which can occur with a certain frequency. This is the case ofsalmonellosis.

Salmonella: how to take it

Theresalmonellosisit is carried by animals such as birds, small mammals and even reptiles such as turtles and snakes. The bacterium ofsalmonellait is spread in various ways, including through the faeces of infected animals which can therefore contaminate an environment.

Faecal contamination would seem a factor to be underestimated: we live in the twenty-first century and we Westerners practice excellent hygiene!

However, despite this premise, we periodically see food scandals and no one seems to be immune. Following a check in 2013, bacteria of fecal origin were found in ikea cakes. If a supply chain as careful as that of a large industry cantripping over certain mistakes, there is to stay in the bell!

Birds and small mammals that deposit their manure in an agricultural field can contaminate fruit and vegetables which, if not carefully washed, can cause infection in humans by ingestion.

THEsymptoms of salmonellosisthey are disparate even if mostmarkedinvolve the digestive system.

Theeggsthey are often pointed out as "guilty" ofinfectionof thesalmonella. In fact, we told you that animal manure contains pathogens capable of transmitting thesalmonellosis to humans.

Eggs are laid in environments that can be in close contact with animal feces. Hens, like other poultry (chickens, peacocks, ostriches, geeseā€¦) can be a possible salmonella reservoir. That's why this pathogen can be found on eggshells and end up on your kitchen counter or utensil surfaces. Again, we hope that the manufacturing company follows all the protocols necessary to avoid the transmission of salmonella.


Theinfectionwith the salmonella bacterium it can be avoided by using common sense and implementing good hygiene practices. Of course, if you are eating in a restaurant and they serve you food contaminated with salmonella, you sadly have no means to "protect yourself". We can only hope that in kitchens and militant industries in the agro-food sector they comply with all the standards required by the HACCP protocol. In our daily life, we can protect ourselves fromsalmonellosisso:

  • If you have pets at home (birds, small mammals or reptiles), submit them to a veterinary examination and, if necessary, submit the animal to specific treatment.
  • Also in the case of pets (birds, rabbits, hamsters ...), carefully clean the cages, shelters or terrariums.
  • Always wash your hands and practice good personal hygiene, especially after a walk in the woods, in the park or in places frequented by wild animals.
  • Avoid consuming food if you have dirty hands.
  • Alas, I know it's tough, but you should avoid raw foods.
  • If you go on a trip, make sure of the hygienic conditions of the place visited and, if necessary, try to consume only packaged food and drink bottled or boiled water.

Salmonellosis: symptoms

Typically, the course of thediseaselasts from 4 to 7 days and iearly symptomsthey appear about 12 - 72 hours after the consumption of contaminated food or accidental ingestion of the pathogen (if you eat healthy food with contaminated hands!).

Although thecareit does not provide for the use of particular drugs, in case of suspected salmonellosis it is advisable to consult your doctor.

Between vulnerable subjects the pregnant women, in this context the people most at risk are:

  • infants and children who have not yet developed a good immune defense.
  • Senior citizens.
  • Patients with transplanted organs.
  • Those suffering from immunosuppressive diseases such as HIV, leukemia and some cancers.
  • Patients undergoing special drug therapies or chemotherapy.
  • Pregnant women.

THEsymptomsof salmonella infection are:

  • Temperature
  • Abdominal pain
  • Gastroenteritis
  • Diarrhea

Salmonellosis in pregnancy

Theresalmonellosis in pregnancyit can pose a risk not to the woman but to the fetus. Infection, in fact, can cause fever and reduced oxygen supply to the placenta with consequent metabolic alterations that can interfere with the optimal development of the fetus.

If you are pregnant, if you suspect the risk of salmonellosis, consult your doctor immediately. There is no need to be alarmed as cases of premature birth induced by salmonellosis or abortion are quite rare, however it is better to be cautious.

The pregnant woman, to reduce the risk of contracting the salmonella bacterium, in addition to avoiding the infection as explained above, should also:

  • Avoid raw or undercooked eggs
  • Do not consume products derived from raw eggs such as mayonnaise or tiramisu
  • Avoid raw or undercooked meat, especially poultry (chicken, turkey, game ...)
  • Do not consume fresh or seasoned sausages (salami, sausages ...)
  • Avoid seafood

Among the other zoonoses dangerous for pregnant women there is toxoplasmosis, but even in this case a good prevention can eliminate any risk.
