Protecting your health after flooding
Floods present many potential health hazards. Emergency workers and other support staff should ensure that members of the public are aware of the potential risks when they return to their homes after a flooding event.
A range of material is available to provide to people who have been affected by floods. When people are planning to return to their homes after the flood waters have subsided, and the risks from floods waters have reduced to a level that is considered safe, there may still be many potential health hazards.
General health information:
• Skin contact with floodwater and mud from floodwater can cause illness and skin infections. If you are injured or suffer a cut during your clean up; clean the wound and contact your doctor immediately.
• Flooding can cause sewage to overflow inside your home. Contact with sewage can make people sick, so contaminated areas must be cleaned and disinfected. And it is best to keep children and pets away until the area is cleaned up.
• People’s private water supplies may also be contaminated from floodwater, debris and chemicals. If your water supply tastes, looks or smells unusual, do not use it for drinking, preparing food, and do not give it to animals. Use bottled water. Boiling water will not make it safe to drink.
• Mosquitoes can also breed rapidly in stagnant waters. So drain any water from containers such as plant pots, tyres, buckets, and roof gutters to control mosquitos around your home.
Prolonged power outages
• Food safety is important during power outages. Once cold or frozen food is no longer cold to touch, it can be kept and eaten for up to four hours and then it must be thrown away.
• Eat hot food within four hours of it being hot or throw it away. If you don’t know how long your food has been unfrozen or not cold to the touch, throw it away.
• If available, put bagged ice under food packages and trays stored in freezers and fridges if power failure lasts more than 1 hour.
• Only open fridge and freezer doors when absolutely necessary, this will keep the food and air temperature colder for longer.
Managing your medications
• Some medicines need to refrigerated between +2°C and +8°C or their effectiveness can deteriorate. These can include vaccines, insulin, thyroxine tablets, immune therapies, some eye drops, some hormone products and some antibiotic mixtures for children.
• If the power has been off for a prolonged period and you are concerned about the quality of your medicines, you should discard them unless it is essential to your immediate health (e.g. insulin).
• Some medicines, such as insulin, which are normally refrigerated can be kept at room temperature (below 25°C) for a specified number of days while you are using them. See the Consumer Medicines Information for the product.
• If you are concerned about a particular medicine, contact your pharmacist or doctor or contact Health Direct on 1800 022 222 for guidance.
If you need to check your property for storm damage and make repairs, remember your own safety.
