Melaleuca has always taken seriously its responsibility to safeguard its products against contamination from bacteria such as Salmonella. Salmonella is not to be taken lightly. Salmonella is an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. It can cause flu like symptoms in healthy people. In rare circumstances, infection with Salmonella can result in the organism getting into the bloodstream and producing more severe illnesses such as arterial infections ( i.e., infected aneurysms ), endocarditis and arthritis.
