Salmonella: A bacteria that can cause diarrhea, stomach cramps and fever

Salmonella are a group of bacteria that infect the gut. 

They live in animal and human intestines and are shed through feces.

Humans become infected most frequently through contaminated water or food. Contamination is possible if raw and cooked foods are stored together.

Symptoms of salmonella infections include diarrhea, 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.

They 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.
