How is salmonella spread?

Page last updated 07 July 2020

Salmonella can be passed from person-to-person or animal-to-person. Salmonella is mainly spread when people eat undercooked or uncooked food made from infected animals or animal products, such as meat, poultry, seafood or eggs.2 Infected people and animals shed bacteria in their faeces, which can also cause food to become contaminated. This most commonly occurs with salads, fruits or vegetables that have been improperly washed and are eaten raw.2 Salmonella ‘cross contamination’ occurs when salmonella contaminates food that is ready to eat, for example, when cooked food comes into contact with contaminated raw food, or when food is handled by an infected person.
