Simple things like washing hands before cooking or eating, and teaching children to do the same, are a great way to start.
One of the most important food safety tips is to always scrub boards and utensils well with hot soapy water between using them with raw food and cooked food.
Don't leave cooked foods at room temperature for any longer than necessary. When you cook ahead of time ensure you keep the food hot until you are ready to eat or, once the steam stops rising, cover and refrigerate for later use. Large portions of food take longer to cool so divide into smaller batches so they cools quickly. Reheat foods thoroughly so they are steaming or boiling and only ever reheat left over food once.
Don't thaw frozen food on the benchtop, allow more time and thaw in the fridge. Or, thaw in the microwave and cook immediately.
