How salmonella bacteria are spread
Salmonella bacteria live in the gut of many farm animals. During rearing, slaughter and processing, the bacteria can be transferred into food products.
Other foods like green vegetables, fruit and shellfish can become contaminated through contact with animal and human faeces. For example, from manure used to improve soil fertility or sewage in water.
Salmonella bacteria can be spread from pets such as cats and dogs to people. They can also be spread from person to person through poor hygiene.
