EPA Alert: potting mix can pose risk to human health
The Environmental Protection Authority (EPA) is alerting consumers to the risks of using pot mix after the tragic
passing of a Christchurch gardener from Legionnaires’ disease (legionellosis).
Ms Lizzie Wilson, spokesperson for the EPA Safer Homes Programme says: “Potting mix is a common gardening supply which
is also sold as potting soil or potting compost.
“This tragic incident highlights the importance of using safety gear when using gardening products around the home,
which in the case of potting mix should extend to wearing gloves and face protection.
“We recommend people read and follow the product’s instructions and labels carefully, which may advise of further safety
measures to minimise the risk to yourself or your family,” says Ms Wilson.
“While the EPA does not have a regulatory role in potting mix, through our Safer Homes Programme we take action to
promote, maintain and enhance consumer safety when using risky substances around the home.”
“We also encourage retailers and manufacturers to review their existing labelling and signage and look for other ways to
reinforce their safety messaging to the public.”
General gardening product safety information is available on the EPA’s website
and a Safer and Healthier Gardening guide produced by the Ministry of Health is available through the HealthEd Portal
EPA tips: take care while you garden
Before you get to work in the garden, check the back of all the products you plan to use to see what you can do to keep
yourself and others safe.
• If you're working on plants that are for eating, check the label to see how long you need to wait before the
plant or vegetable will be safe to eat. Write this down somewhere so you don’t forget.
• Wear gloves, and check the label to see if you need other protection like a face mask or safety glasses.
• Keep products away from your eyes and face, and off your skin.
• Choose a calm day. Wind can blow products into your eyes and face, or onto other people.
• Be very careful if you are working near streams or other water. Many garden products should not be used near
water. Never pour leftover products down stormwater drains.
• Ask your local your garden centre for advice and always read labels before you buy and use. Do not buy or use
products that don’t have labels.
You should remember:
• to seek advice to select the safest and most effective product for the job. You can make your home and garden
safer by choosing products that are as gentle as possible. The staff at the store where you buy your products may be
able to help with this.
• that ‘natural’, ‘organic’, and ‘environmentally friendly’ products can still be hazardous.
• that you should always keep gardening products in their original packages or containers.
