Te Whatu Ora is urging green fingered kiwis to guard
against Legionnaires’ disease during the spring and summer
gardening season.
Legionnaires’ disease or
Legionellosis is an uncommon but dangerous
‘gardener’s’ pneumonia. There are various types, but
one of the main strains is often caused by bacteria found in
compost and potting mixes.
Medical Officer of Health
Dr David Sinclair from the National Public Health Service
says case numbers in New Zealand often spike in September,
October and November during spring gardening
season.
“Legionnaires’ disease can be fatal, but
it’s also very easy for gardeners to protect themselves
against it” said Dr Sinclair.
“By following a few
simple precautions you can reduce your risk when handling
compost and potting mix. Most importantly dig out a
well-fitting facemask to wear, put on gloves, damp down soil
and wash your hands when you’re done.”
Public health
services across New Zealand have already started seeing an
uptick in spring time Legionnaires’ disease
notifications.
In the Auckland region case numbers for
all types of Legionnaires’ disease in 2022 are the highest
they’ve been in five years, while nationally there have
been more than 140 cases in the year to
date.
Typically, around 60% of Legionnaires’ disease
cases each year are the Longbeachae type, which is linked to
the bacteria found in compost and potting mix.
Te
Whatu Ora is keen to reduce the risk of further cases this
year particularly given the serious health outcomes
Legionnaires’ disease can cause.
“The disease is
uncommon but it can be really severe, so it’s important to
take it seriously” added Dr Sinclair.
“The risk is
higher for older people, as well as those who smoke, have
lung conditions or a weakened immune system. As it can’t
be spread from person to person it’s quite simple to keep
yourself safe.
“Gardeners just need to remember to
gear up when they get out there this Labour weekend and
beyond.”
