Salmonella bacteria can cause food poisoning. Here’s what you should know if you think you’ve been infected.

What are the symptoms and how long do they last?

Symptoms include diarrhoea, stomach cramps and sometimes vomiting and fever.

On average, it takes from 12 to 72 hours for the symptoms to develop after swallowing an infectious dose of salmonella.

Symptoms usually last for four to seven days and most people recover without treatment.

But if you become seriously ill, you may need hospital care because the dehydration caused by the illness can be life-threatening.

Who gets salmonella?

Anyone can get salmonella, but young children, the elderly and people who have immune systems that are not working properly (including people with cancer, AIDS or alcoholism) have a greater risk of becoming severely ill.

How do you get infected with salmonella?

You usually get salmonella by eating contaminated food. Salmonella bacteria live in the gut of many farm animals and can affect meat, eggs, poultry and milk. Other foods like green vegetables, fruit and shellfish can become contaminated through contact with manure in the soil or sewage in the water.

Contamination is also possible if raw and cooked foods are stored together. Most tortoises and terrapins and other pet reptiles can also carry salmonella. Dogs, cats and rodents can occasionally become infected.

It is impossible to tell from its appearance whether food is contaminated with salmonella. It will look, smell and taste normal.

Salmonella can be spread from person to person by poor hygiene, by failing to wash your hands properly after going to the toilet, or after handling contaminated food.

How can you avoid getting infected with salmonella?

Wash your hands thoroughly with soap and warm water:

before preparing and eating food
after handling raw food
after going to the toilet or changing a baby’s nappy
after contact with pets and other animals, especially reptiles and amphibians
after working in the garden

Also:

keep cooked food away from raw food
store raw foods below cooked or ready-to-eat foods in the fridge to prevent contamination
wash raw fruits and vegetables thoroughly before eating
cook food thoroughly, especially meat, so that it is piping hot
keep all kitchen surfaces and equipment including knives, chopping boards and dish cloths clean
do not drink untreated water from lakes, rivers or streams
do not keep reptiles or amphibians in households where there is a child under 5 year of age, or someone with a weakened immune system

If someone has salmonella, wash all dirty clothes, bedding and towels in the washing machine on the hottest cycle possible.

Clean toilet seats, toilet bowls, flush handles, taps and wash hand basins after use with detergent and hot water, followed by a household disinfectant.

How do you treat salmonella?

It is important to drink plenty of fluids as diarrhoea or vomiting can lead to dehydration and you can lose important sugars and minerals from your body. Your doctor may recommend a rehydration solution, available from your pharmacist.

Sometimes severe cases are treated with antibiotics. If you are given antibiotics, it is essential that you complete the course as prescribed.

Do you need to stay off work or school?

Yes. While you are ill and have symptoms, you are infectious. Children and adults should stay away from nursery, school or work for 48 hours after the symptoms have stopped.

You should tell your employer you have had salmonella if you work with vulnerable groups such as the elderly, the young or those in poor health, or if you handle food.
