Salmonella is a genus of bacteria that cause illness in humans when transmitted through foods contaminated with faeces. It’s often found on fruits and vegetables, originating in the growing or irrigation media. Illnesses commonly include typhoid fever, paratyphoid fever and food poisoning.

This is why testing for faecal pathogens, which include Salmonella enterica, is a requirement of Australian Standards compliance testing for composts, soil conditioners and mulches (AS4454) and soils for landscaping and garden use (AS4419) for effective management of pathogen risk in products made of composted wastes.

SESL Australia offers comprehensive testing packages for composted products (compost, mulches and soils) to assist with Standards compliance, and employs experienced consultants who can offer advice. Please contact us at or on 1300 30 40 80.
