With 10 cases of Legionnaires disease in Christchurch over the past week, gardeners are being warned to take precautions. Compost and potting mix are the primary contributors to contracting the disease.
Medical Officer of Health Alistair Humphrey joins Lisa Owen on The Long Lunch to explain how they are investigating the outbreak through afflicted patients.
Dr Humphrey explains that Canterbury has many keen gardeners, hence the high rate of the potentially-fatal disease.
"Cut the bag open," he advises gardeners when handling potting mix. "Don’t rip the bag open."
Masks and gloves are also recommended when dealing with compost and potting mix, he explains.
Canterbury has the country's highest rates of Legionnaires while New Zealand has the highest reported cases of the disease in the world.
