Soil may contain Legionella bacteria – follow safe handling practices
Spring is a busy time for gardeners. It is important to pay attention to the safe handling of soil and compost products in gardens and allotments, as soil can contain Legionella bacteria.
Legionella bacteria naturally occur in soil and natural waters in small amounts. Under favourable conditions, especially in moist environments and at temperatures between 20 °C and 45 °C, the bacteria can multiply rapidly. In such cases, they can cause a serious form of pneumonia that can be contracted through the respiratory tract or via wounds.
Factors that increase the risk of developing pneumonia caused by Legionella include advanced age, smoking, lung disease and a weakened immune system. Even otherwise healthy people can become ill, although their risk is lower.
When handling soil or compost products, follow these practices to reduce exposure to Legionella bacteria:
- When opening a bag of soil, turn the bag away from your face.
- Handle soil gently to prevent dust from spreading into the air.
- Moisten the soil or compost with water using low pressure.
- Store the soil bags in the shade and, if possible, in a cool place.
- Wear protective gloves and wash your hands thoroughly after gardening.
- Protect any wounds.
- If necessary, use an FFP2 or FFP3 mask.
- When cleaning soil-covered tools with water, use low water pressure.
If you develop a sudden fever, respiratory symptoms or a cough after gardening, seek medical attention and tell the health care staff about your possible exposure.
