| Legionella longbeachae McKinney et al. 1982 |
Legionella longbeachae is one species of the family Legionellaceae. It is found predominantly in soil and potting compost. Human infection from L. longbeachae is particularly common in Western Australia,[1],[2] yet cases have been documented in other countries including the USA.[3]
Like other Legionella species, person-to-person transmission has not been documented. However, unlike other species the primary transmission mode is inhalation of dust from contaminated compost or soil that contains the organism causing legionellosis.[4]
[edit] Compost
Compost must be handled with care, damp down with water to reduce dust before handling, use a face mask covering nose and mouth to reduce the risk of inhaling the dust, especially for those at high risk from infection.
It is noteworthy that compost packaging in Australia has a L. longbeachae warning label.
